A secant ogive of sharpness E = 120/100= 1.2 The ogive shape of the Space Shuttle External Tank Ogive on a 9×19mm Parabellum cartridge An ogive ( ) is the roundly tapered end of a two-dimensional or three-dimensional object. Ogive curves and surfaces are used in engineering, architecture and woodworking.

The profile of this shape is also formed by a segment of a circle, but the base of the shape is not on the radius of the circle defined by the ogive radius. The rocket body will not be tangent to the curve of the nose at its base. The ogive radius is not determined by and (as it is for a tangent ogive), but rather is one of the factors to be chosen to define the nose shape. If the chosen ogive radius of a secant ogive is greater than the ogive radius of a tangent ogive with the same and , then the resulting secant ogive appears as a tangent ogive with a portion of the base truncated.

This is a very common ogive for high velocity (supersonic) rifle bullets. The sharpness of this ogive is expressed by the ratio of its radius to the diameter of the cylinder; a value of one half being a hemispherical dome, and larger values being progressively more pointed. Values of 4 to 10 are commonly used in rifles, with 6 being the most common. Another common ogive for bullets is the elliptical ogive.

Ogive was born to Frederick of Luxembourg and his wife Irmtrud of Wetterau. Her probable birth date of 995 makes it likely that she was one of Frederick's eldest children. Ogive married Baldwin IV, Count of Flanders, who sought to strengthen his connection to the royal house by marrying this niece of Queen Cunigunde of Germany. Ogive had a son in 1012, also called Baldwin.

This is a curve very similar to the spitzer ogive, except that the circular arc is replaced by an ellipse defined in such a way that it meets the axis at exactly 90°. This gives a somewhat rounded nose regardless of the sharpness ratio. An elliptical ogive is normally described in terms of the ratio of the length of the ogive to the diameter of the shank. A ratio of one half would be, once again, a hemisphere.

In ballistics or aerodynamics, an ogive is a pointed, curved surface mainly used to form the approximately streamlined nose of a bullet or other projectile, reducing air resistance or the drag of air. In fact the French word ogive can be translated as "nose cone" or "warhead". The traditional or secant ogive is a surface of revolution of the same curve that forms a Gothic arch; that is, a circular arc, of greater radius than the diameter of the cylindrical section ("shank"), is drawn from the edge of the shank until it intercepts the axis. If this arc is drawn so that it meets the shank at zero angle (that is, the distance of the centre of the arc from the axis, plus the radius of the shank, equals the radius of the arc), then it is called a tangent or spitzer ogive.

The last intersection gives us the desired value. The frequency polygon and ogive are used to compare two statistical sets whose number could be different.
|
|
Along the horizontal axis the limits of the class intervals for an ogive are marked. Based on the limit values, points above each are placed with heights equal to either the absolute or relative cumulative frequency. The shape of an ogive is obtained by connecting each of the points to its neighbours with line segments. Sometimes an axis for both the absolute frequency and relative is drawn.

Chicago: Scientific Software, Inc. This means it is technically possible to estimate a simple IRT model using general-purpose statistical software. With rescaling of the ability parameter, it is possible to make the 2PL logistic model closely approximate the cumulative normal ogive. Typically, the 2PL logistic and normal-ogive IRFs differ in probability by no more than 0.01 across the range of the function.

A secant ogive Further thinking on the subject envisions a hardened penetrator using kinetic energy to defeat the target's defenses and subsequently deliver a nuclear explosive to the buried target. The primary difficulty facing the designers of such a penetrator is the tremendous heat applied to the penetrator unit when striking the shielding (surface) at hundreds of meters per second. This has partially been solved by using metals such as tungsten (the metal with the highest melting point), and altering the shape of the projectile (such as an ogive). Altering the shape of the projectile to incorporate an ogive shape has yielded substantial improvement in penetration ability.

An ogive or ogival arch is a pointed, "Gothic" arch, drawn with compasses as outlined above, or with arcs of an ellipse as described. A very narrow, steeply pointed ogive arch is sometimes called a "lancet arch". The most common form is an equilateral arch, where the radius is the same as the width. In the later Flamboyant Gothic style, an "ogee arch", an arch with a pointed head, like S-shaped curves, became prevalent.

Values close to 1 are common in practice. Elliptical ogives are mainly used in pistol bullets. Missiles and aircraft generally have much more complex ogives, such as the von Kármán ogive.

Built in 1886, Trinity is the oldest of Tilden's surviving designs in Canton. Its foundation is stone, with an asphalt roof and sandstone walls. The bell tower, located on the left from the perspective of a viewer across the street, features an entrance in the base and tall ogive windows that extend for the majority of the tower's height. Smaller ogive windows pierce the top section of the tower, which is crowned by a steep pyramidal roof.

The LOX tank is located at the top of the ET and has an ogive shape to reduce aerodynamic drag and aerothermodynamic heating. The ogive nose section is capped by a flat removable cover plate and a nose cone. The nose cone consists of a removable conical assembly that serves as an aerodynamic fairing for the propulsion and electrical system components. The forward most element of the nose cone functions as a cast aluminium lightning rod.

In 1947, studies into wave drag led to the development of perfect shapes to reduce wave drag as much as theoretically possible. For a fuselage the resulting shape was the Sears–Haack body, which suggested a perfect cross- sectional shape for any given internal volume. The von Kármán ogive was a similar shape for bodies with a blunt end, like a missile. Both were based on long narrow shapes with pointed ends, the main difference being that the ogive was pointed on only one end.

In contrast to full-length resizing of bottleneck rifle cartridges, which can rapidly thin out the wall thickness of bottleneck rifle cartridges due to case stretching that occurs each time when fired, partial length re-sizing of the bottleneck case that pushes shoulders back only a few thousandths of an inch will often permit a case to be safely reloaded 5 times or more, even up to 10 times, or more for very light loads. Similarly, by using modified case gauges, it is possible to measure precisely the distance from a bullet ogive to the start of rifling in a particular rifle for a given bottleneck cartridge. Maximum accuracy for a rifle is often found to occur for only one particular fixed distance from the start of rifling in a bore to a datum line on a bullet ogive. Measuring the overall cartridge length does not permit setting such fixed distances accurately, as different bullets from different manufacturers will often have a different ogive shape.

Some firearms, like the FN Five-seven, have a beveled chamber instead of a feed ramp. The feed ramp is a critical part of semi-automatic firearms and automatic firearms. When the pistol is fired and the spent case is ejected, the feed ramp functions to direct a fresh cartridge from the magazine into firing position; that is, the fresh cartridge slides along the feed ramp into battery. The need for the cartridge to slide both forwards and upwards along the feed ramp and into the barrel is the primary design consideration that makes the ogive the preferred shape for all modern automatic pistol rounds (a hollow point bullet is a truncated ogive), as there are many other shapes that are stable in ballistic flight.

Then, he extended this line by one soldo in either direction, and made marks one soldo beyond the base line. He then centered a compass or string on these marks and laid out the circular form of the arches with a radius of 14 soldi.

Several other attempts to reduce wave drag have been introduced over the years. The supercritical airfoil is a type that results in reasonable low speed lift like a normal airfoil, but has a profile considerably closer to that of the von Kármán ogive.

Tallboys were largely hand-made, requiring much labour during each manufacturing stage. The materials used were costly, with precise engineering requirements in casting and machining. To increase penetrative power, a large, specially hardened, steel plug had to be precisely machined and mated to a recess in the nose of the bomb. The ogive had to be perfectly symmetrical to ensure optimum aerodynamic performance.

The illumination of church's interior creates unique paradox. Meanwhile, central area is illuminated only indirectly the side walkway parts of the church are awash with light. This light permeates into central area of the church by ogive arches placed in places where should stand the bearing pillars. The stucco decoration underlines this paradox by creating relation between wall and arch belonging to that particular wall.

The Mark 11 nose was a pointed ogive shape. The MK-11 also known as the MK-91 had variable yields by changing the target rings. A major difference over the MK-8 was that the MK-91 had an electric operated actuator as a safety device that would rotate a spline ring to prevent the projectile from being fired into the target rings. The MK-8 had no safety devices.

The closed form solution for the minimum wave drag of a body of revolution with a fixed length was found by Sears and Haack, and is known as the Sears-Haack Distribution. Similarly, for a fixed volume, the shape for minimum wave drag is the Von Karman Ogive. The Busemann biplane is not, in principle, subject to wave drag when operated at its design speed, but is incapable of generating lift in this condition.

The XM1128 follows (and is based on) production and test articles from the boosted M795-series rounds—specifically the M795E1 and M795E2. The XM1128 consists of a high fragmentation steel body with a streamlined ogive and a drag-reducing base burner. The projectile body is filled with insensitive explosive (IMX-101) and a supplementary charge. On gun launch propellant gases enter the base burner cavity and ignite dual tracer cups in the ignition assembly.

This highest point is typically estimated with IRT software using the Newton-Raphson method. While scoring is much more sophisticated with IRT, for most tests, the (linear) correlation between the theta estimate and a traditional score is very high; often it is .95 or more. A graph of IRT scores against traditional scores shows an ogive shape implying that the IRT estimates separate individuals at the borders of the range more than in the middle.

The opposite is true when comparing the .260 Remington to the 6.5mm Creedmoor: They are nearly-identical but the Creedmoor can take a higher chamber pressure than the .260 Remington, leading the Creedmoor to have more room for a longer bullet (more aerodynamically efficient, higher sectional density than most shorter bullets) in a given magazine length or cartridge overall length than the .260 Remington's maximum projectile length or ogive length, and yet the .

These projectiles consist of two major components, a warhead filled with 16 pounds of Composition B high explosive (M549) or 15 pounds of TNT high explosive (M549A1), and a solid propellant rocket motor. These components are threaded together so that the outer steel shells of both form a streamlined ogive. A supplementary charge is installed in the deep cavity of the nose. A rotating band encircles the assembled projectile near the base.

During World War II, man-portable antitank weapons using shaped charge warheads, more commonly known today as HEAT projectiles, came into widespread use with almost all armies. These warheads have the advantage of not being affected by the projectile's velocity. They penetrate armour by the detonation of an explosive charge fitted in a liner in the shape of a cone or, more precisely, an ogive. The liner is often made of a soft metal, such as copper.

Initially, there were three cartridges. Sub-zones 1 and 2 were only used to provide short range in high angle fire, and were soon replaced by a plastic spoiler slipped over the shell ogive. Normal cartridge gave charges 1–5, each bag being a different colour in accordance with established UK practice, Mk 1 normal cartridge only went to charge 4. Both marks had charge Super, a single charge cartridge, although the charge was reduced in Mk 1.

During the 20th Century, shells became increasingly streamlined. In World War I, ogives were typically two circular radius head (crh) – the curve was a segment of a circle having a radius of twice the shell caliber. After that war, ogive shapes became more complex and elongated. From the 1960s, higher quality steels were introduced by some countries for their HE shells, this enabled thinner shell walls with less weight of metal and hence a greater weight of explosive.

The nave has 7 bays, with side chapels all along the aisles, and the choir extends the nave and ends in a semi- circular apse. The choir and aisles are covered by an ogive vault and the nave by a barrel vault.

The earliest use of the word ogive is found in the 13th century sketchbook of Villard de Honnecourt, from Picardy in northern France. The Oxford English Dictionary considers the French term's origin obscure; it might come from the Late Latin , the feminine perfect passive participle of , meaning the one who has met or encountered the other. However, Merriam-Webster's dictionary says it is from the "Middle English stone comprising an arch, from Middle French diagonal arch".

Baldwin was born into the House of Flanders, the son of Baldwin IV of Flanders and Ogive of Luxembourg. Baldwin married Adela, daughter of King Robert II of France, in 1028 in Amiens; at her instigation he rebelled against his father but in 1030 peace was sworn and the old count continued to rule until his death. The couple had three children: Baldwin VI (1030–1070), Matilda ( 1031–1083), who was married to William the Conqueror, and Robert I ( 1033-1093).

The nave is on three levels with a triforium. The ogive vaults seem to have been begun around 1120, but it is thought the vaulted Romanesque choir was completed before this date. Well understood from 1950s excavations, the Romanesque choir was demolished sometime between 1500 and 1525 to make room for a new one in Flamboyant Gothic, rapidly given stained glass windows which survived the French Revolution and are the most notable feature of the church. The church was made a monument historique on 25 April 1846.

The latter was rebuilt during the 12th century, showing the artistic originality developed by the Plantagenet court. The choir include ogive vaults and the former building was completely redesigned, trying to make the maximum use of space in the old building. Between each window is a caryatid resting on a half-column. These show figures from the Old and New Testaments and may be the first of their kind, before the Plantagenets popularized them throughout their lands in Maine and Anjou - previously column-statues were more common in doorways than interiors.

This was achieved by removing the bottleneck shape of the 7.65×21mm Parabellum case, resulting in a tapered rimless cartridge encasing a bullet that was 9 mm in diameter. In 1902, Luger presented the new round to the British Small Arms Committee, as well as three prototype versions to the U.S. Army for testing at Springfield Arsenal in mid-1903. The Imperial German Navy adopted the cartridge in 1904 and in 1908 the German Army adopted it as well. The ogive of the bullet was slightly redesigned in the 1910s to improve feeding.

From 1209, construction began of a more important castle, rectangular in plan, with a tower in each corner. The guard room, the lower hall with ogive vaults and the cellars are the last elements which constituted the 13th- century castle, the episcopal palace at that time. During the Hundred Years' War, the building was transformed into a fortress; it was taken from the English by Joan of Arc on 14 June 1429. At the end of the 15th century and start of the 16th century, building to the north incorporated a tower with a drawbridge.

The first example of an early Gothic arch in Europe is in Sicily in the Greek fortifications of Gela. The semicircular arch was followed in Europe by the pointed Gothic arch or ogive, whose centreline more closely follows the forces of compression and which is therefore stronger. The semicircular arch can be flattened to make an elliptical arch, as in the Ponte Santa Trinita. Parabolic arches were introduced in construction by the Spanish architect Antoni Gaudí, who admired the structural system of the Gothic style, but for the buttresses, which he termed "architectural crutches".

Erik Satie in the late 1880s The Ogives are four pieces for piano composed by Erik Satie in the late 1880s. They were published in 1889, and were the first compositions by Satie he did not publish in his father's music publishing house. An example of French Gothic orgival arches, the type that inspired Satie's Ogives Satie was said to have been inspired by the form of the windows of the Notre Dame Cathedral in Paris when composing the Ogives. An ogive is the curve that forms the outline of a pointed gothic arch.

The palace is located in the city of Piacenza, in Northern Italy, on the banks of the River Po. In 1281, the ghibellin Alberto Scoto, wanted to build the palace and sent for four architects from Piacenza: Pietro da Cagnano, Negro De Negri, Gherardo Bellman and Pietro da Borghetto. Following the first project, the palace should have been quadrangular, but work was stopped due to an epidemic plague. Only the north side of the palace was finished. The result is an excellent example of civil ogive architecture in lombard Gothic style.

The only external difference between the two versions was the nose cone, which was an ogive for the SARH seeker, and shorter (by 30 cm) and more rounded for the IR version. The R-23 had a probability of kill of 0.8-0.9, though it could not hit a target pulling more than 5g. The launching aircraft was also limited to 4g when it wished to fire the missile. The infrared R-23T had a minimum launch range of 4 km against a target that was head-on, but only 1.3 km against a target when it had a view of its rear.

The gavit, the distinctive Armenian style of narthex, appeared in the tenth and eleventh centuries.Medieval Armenian architecture: constructions of race and nation Christina Maranci – 2001 "Unlike Strzygowski, who stressed the importance of race and nation in the formation of architecture, ... Another structure at Ani also provided Baltrusaitis with an ogive — the narthex or gavit' located at the south side of the church." The first were located in the south of the Armenia in the region of Syunik. The type of construction changed during the twelfth and fourteenth centuries, as found in the monasteries of Saghmosavank of Haritchavank, or Hovhannavank Monastery.

Among the prominent architectural elements of this Gothic Revival house are elaborate bargeboards at the ends of its tall gables; the roof is steeply pitched, and the house's shape is broken by a small "side" gable that includes a shutter-covered ogive window over the main entrance. Piercing the walls are two doors, both of which possess small but elaborate hand-carven trim and brackets. In 1987, the Robinson-Pavey House was listed on the National Register of Historic Places, qualifying because of its distinctive architecture; at the time of designation it was one of just two Gothic Revival houses in the city.

At the same time, Zion differs from the typical Carpenter Gothic church in its use of angled gable- shaped windows instead of the ogive traditional in Gothic Revival buildings. Worshippers enter the building though double doors in the base of the tower, above which are placed one large window and one small. A belfry with louvering occupies the highest level of the tower, above which stands a cross-tipped steeple. The roof rises steeply to front and rear gables, with a small section of the roof and much of the front gable being obscured by the tower.

Its floor plan is reminiscent of many other Anglican churches, with the typical tower atop the narthex and the rectangular nave. In a similar manner, the building is constructed in the shape of a cross, due to the construction of transepts connected to the chancel. Even the tower is reminiscent of traditional Anglican churches, due to the presence of a belfry with a steep pyramid-shaped roof and louvred openings. The main body of the church features ogive windows and a gabled facade, while small cloverleaf-shaped windows are placed in the tower above the entrance and below the main windows.

|
The interior's single nave is surmounted by cross vaults, supported by Gothic buttresses. The side walls feature a triforium with pointed-arch stained glass windows. The apse is separated from the nave by a wall reaching to the vaulted ceiling and perforated with openings, namely one enormous ogive or pointed arch in the center framing the high altar, flanked by two smaller pointed arches as entrances to the ambulatory at the apse. The upper reaches of the wall bear a large central rose window (1705, dedicated to the Archangel St. Michael) flanked by two smaller ones.

In addition to the 40 mm SCORPION, a 25 mm SCORPION was also developed. Designed similarly to the 40 mm model, the 25 mm SCORPION munition consisted of two sections, the electronic control module and the actuator module. The electronic control module was a potted cylindrical container that houses the power, driver, IMU, processor, and connector boards as well as a removable ogive that provided the user with access to communication and data. The projectile also included the command guidance and the inertial sensor suite (ISS), the latter of which held the oscillator board, the processor board, and the sensor suite.

Cast bullets require a longer bearing surface than jacketed bullets to maintain an equivalent alignment with the bore of the firearm; because the softer cast bullet can be more readily deformed. The most successful cast bullet designs have a round or flattened nose rather than a long, unsupported ogive. Bullet designs with a forward diameter designed to be supported on the rifling lands work best in barrels rifled with wide lands and narrow grooves like the 2-groove M1903-A3 rifles. Forward bearing surfaces of full groove diameter provide more effective alignment in barrels with wide grooves and narrow lands, provided the chamber throat is long enough to accept such bullets.

An aircraft that can accelerate past this speed sees a significant drag decrease, and can fly supersonically with improved fuel economy. However, due to the way lift is generated supersonically, the lift-to-drag ratio of the aircraft as a whole drops, leading to lower range, offsetting or overturning this advantage. The key to having low supersonic drag is to properly shape the overall aircraft to be long and thin, and close to a "perfect" shape, the von Karman ogive or Sears-Haack body. This has led to almost every supersonic cruising aircraft looking very similar to every other, with a very long and slender fuselage and large delta wings, cf.

The present building, a Gothic Revival structure, is a rusticated stone building designed by Peters, Burns, and Pretzinger. Its general appearance was intended to resemble that of the most prominent Lutheran churches in Europe, so the architects included stained glass portraits of certain of the Twelve Apostles and Four Evangelists, traditional details such as label stops with figureheads, and a painted ceiling with visible structural elements. Among the most prominent aspects of the overall design are a central tower tall, tall but thin ogive windows, and the use of stone with multicolored veins for the exterior walls. It is the only extant downtown church in the Gothic Revival style.

There are some types of all-steel subcaliber slugs supported by a plastic sabot (the projectile would damage the barrel without a sabot). Examples include Russian "Tandem" wadcutter-type slug (the name is historical, as early versions consisted of two spherical steel balls) and ogive "UDAR" ("Strike") slug and French spool- like "Balle Blondeau" (Blondeau slug) and "Balle fleche Sauvestre" (Sauvestre flechette) with steel sabot inside expanding copper body and plastic rear empennage. Made of non-deforming steel, these slugs are well-suited to shooting in brush, but may produce overpenetration. They also may be used for disabling vehicles by firing in the engine compartment or for defeating hard body armor.

Its buttressed limestone walls set it apart from all other churches in the city, as no other limestone churches were built in Hillsboro in the nineteenth century. Lit by six ogive-arch windows, the interior features oaken pews installed at the time of construction, a lofty vaulted ceiling, and wainscoting made of marble. In 1988, St. Mary's Church and its rectory were together listed on the National Register of Historic Places, qualifying because of their distinctive historic architecture. The combined property is one of more than thirty current and former Episcopal churches on the Register in Ohio, and one of twenty-six Register-listed properties in Highland County.

The prayer hall is aligned below the first five of the nine bays that run parallel to the qibla wall. Great Mosque of Algiers (1899) Great Mosque of Algiers in modern times The mihrab, which was originally built as an integral part of the mosque in 1097, was destroyed in bombing in AD 1682 (AH 1093). The reconstructed mihrab is a typical design followed in 18th-century Algiers in the form of indented lobed arches at the end of the central and much wider nave. It is a simple fresco façade with two small spiral columns flanking it on either side with an ogive stucco arch seen in relief.

This appears to be a new form of drag—referred to as wave drag—which peaks at about three times the drag at speeds even slightly below the critical mach. In order to minimize the wave drag, the curvature of the aircraft should be kept to a minimum, which implies much higher fineness ratios. This is why high-speed aircraft have long pointed noses and tails, and cockpit canopies that are flush to the fuselage line. More technically, the best possible performance for a supersonic design is typified by two "perfect shapes", the Sears-Haack body which is pointed at both ends, or the von Kármán ogive, which has a blunt tail.

When a large calibre APDS is fired and while still within the bore, the setback forces shear the forward petals, partly unlocking the sub-projectile from the sabot, but still holding it rigidly within the pot. Gas pressure is used to delay the unlocking of the pins holding the rear part of the sub- projectile by gyroscopic forces. Once outside the barrel, the pins, centering band and forward petals are released or discarded by projectile spin, the aerodynamic drag removes the pot/base unit. As an APDS sub-projectile does not require driving bands and the core is supported at the base and ogive region, a far more aerodynamic projectile shape can be chosen.

A number of new techniques developed during and just after World War II were able to dramatically reduce the magnitude of wave drag, and by the early 1950s the latest fighter aircraft could reach supersonic speeds. These techniques were quickly put to use by aircraft designers. One common solution to the problem of wave drag was to use a swept wing, which had actually been developed before World War II and used on some German wartime designs. Sweeping the wing makes it appear thinner and longer in the direction of the airflow, making a conventional teardrop wing shape closer to that of the von Kármán ogive, while still remaining useful at lower speeds where curvature and thickness are important.

When shooting paper targets, they cut a relatively clean hole in the target, yet provide more case volume and a better ballistic coefficient than a flat front wadcutter. When used for hunting, the heavy bullets provide excellent penetration; they are often used on dangerous game, for which more reliable penetration is required than is possible with expanding hollow point or soft point bullets. Keith-Style SWCOriginally Keith specified a meplat that was 65% of the bullet caliber, but later increased it to a 70% meplat. The other distinguishing characteristics of a "Keith-style" SWC are a double radius ogive, beveled crimp groove, three equal width driving bands, wide square bottomed grease groove, and a plain base with sharp corners.

A follow-up meeting started planning for a number of committees to study development of the concept, but worried that this would lead to lengthy delays, Burls decided to allow Cossor a free hand to develop the guidance system while (the now Major) Sedgfield would handle rocket development at the AA Command's workshops at Park Royal. Development began in February 1944. The Brakemine missile developed as a simple cylindrical airframe with an ogive nosecone, small elliptical wings mounted near the centre of gravity, and four small fins at the rear. The missile was powered by eight solid rockets taken from the existing Unrotated Projectile anti-aircraft rocket (also used on the RP-3); later models used six rockets.

For these reasons, in 1926, the ordnance corps, after extensive testing of 7.5×55mm Swiss GP11 projectiles provided by the Swiss developed the .30 M1 Ball cartridge loaded with a new improved military rifle (IMR) 1185 propellant and bullet with a 9° boat-tail and an ogive of 7 calibers nose cone that had a higher ballistic coefficient of roughly 0.494 (G1 BC), that achieved a muzzle velocity of and muzzle energy of . This bullet further reduced air resistance in flight, resulting in less rapid downrange deceleration, less lateral drift caused by crosswinds, and significantly greater supersonic and maximum effective range from machine guns and rifles alike.FM 23-10 Basic Field Manual: U.S. Rifle Caliber .

Case capacity is 167.5 grains. Factory loads drive a 266 grain bullet at 3350 feet per second from a 30" barrel. The factory loads are loaded with a Tellurium Copper alloy solid very-low-drag bullet, These projectiles are manufactured by Xtreme Machining and of a patent pending design. The secant ogive projectile measures 1.808" long, including a 6 degree boat tail of 0.285". The patent refers to a "dual diameter" aspect of the projectile, where the main cylindrical portion of the bullet measures 0.331", 0.001" greater than the lands of the rifling. About 1.440" from the tip, the diameter increases to 0.338", creating a 0.15" "driving band". This both reduces driving force required for the high muzzle velocity as well as improves accuracy.

Also, unlike Foster slugs that have thin fins on the outside of the slug, much like those on the Brenneke, the wad slug is shaped with an ogive or bullet shape, with a smooth outer surface. The wad slug is loaded using a standard shotshell wad, which acts like a sabot. The diameter of the wad slug is slightly less than the nominal bore diameter, being around 0.690 inch (17.5 mm) for a 12-gauge wad slug, and a wad slug is generally cast solely from pure lead, necessary for increasing safety if the slug is ever fired through a choked shotgun. Common 12 gauge slug masses are oz, 1 oz, and 1 oz, the same as common birdshot payloads.

Thunderbird at RAF Museum Cosford EE's design quickly developed into a fairly simple cylindrical fuselage with an ogive nose cone, four cropped-delta wings just behind the middle point of the fuselage, and four smaller control surfaces at the rear, in-line with the mid-mounted wings. The fuselage had a slight boat-tail narrowing at the extreme rear under the control surfaces. The sustainer was to be a liquid fuel rocket developed for the missile, and was launched by four large "Gosling" solid fuel rocket boosters lying between the control surfaces and wings. The boosters featured a single oversized fin of their own, and are particularly easy to spot due to a small flat surface at the end of every fin.

The tower interiors show more evidently the complex history of the building: on the first floor - indeed, next to the loophole windows of the military period - is an ogive window of the 15th century. The scraps of fresco remaining on the walls and the niches cut into them are evidence that in the Lombard period this room was used as the burial place of the abbesses. Among those frescoes still legible can be made out the figure of a nun which has in the inscription the typically Lombard name of Aliberga, and a cross with the Alpha and Omega on the horizontal arms. Among the materials reused for the construction of this floor is a piece of Roman marble with a relief carving of a crested helmet.

Before-and-after detonation of a K11A1 continuous rod warhead intended for Bloodhound Mk.2 The main missile is a long cylinder of magnesium frames and aluminium alloy skin with a prominent ogive nose cone at the front and some boat-tailing at the rear. Small aluminium-covered wooden cropped-delta wings are mounted midpoint, providing pitch and roll control by pivoting in unison or independently with additional steering provided by differential fuel feed to each of the ram jets. Two smaller rectangular fixed surfaces were mounted in-line with the main wings, almost at the rear of the missile. The boost engines are held together as a single assembly by a metal ring at the rear of the missile.

The various elements of Gothic architecture emerged in a number of 11th and 12th century building projects, particularly in the Île de France area, but were first combined to form what we would now recognise as a distinctively Gothic style at the 12th century abbey church of Saint-Denis in Saint-Denis, near Paris. Verticality is emphasized in Gothic architecture, which features almost skeletal stone structures with great expanses of glass, pared-down wall surfaces supported by external flying buttresses, pointed arches using the ogive shape, ribbed stone vaults, clustered columns, pinnacles and sharply pointed spires. Windows contain stained glass, showing stories from the Bible and from lives of saints. Such advances in design allowed cathedrals to rise taller than ever.

Although data are not available for many shapes in the transonic region, the table clearly suggests that either the Von Kármán shape, or power series shape with , would be preferable to the popular conical or ogive shapes, for this purpose. General Dynamics F-16 with a nose cone very close to the Von Kármán shape This observation goes against the often-repeated conventional wisdom that a conical nose is optimum for 'Mach- breaking'. Fighter aircraft are probably good examples of nose shapes optimized for the transonic region, although their nose shapes are often distorted by other considerations of avionics and inlets. For example, an F-16 Fighting Falcon nose appears to be a very close match to a Von Kármán shape.

It is only by measuring from a fixed diameter point on a bullet ogive to the start of a bore's rifling that a proper spacing can be determined to maximize accuracy. A modified case gauge can provide the means by which to achieve an improvement in accuracy with precision handloads. Such head space gauges and modified case gauges can, respectively, permit greatly increasing the number of times a rifle bottleneck case can be reloaded safely, as well as to improve greatly the accuracy of such handloads. Unlike the situation with using expensive factory ammunition, handloaded match ammunition can be made that is vastly more accurate, and, through reloading, that can be much more affordable than anything that can be purchased, being customized for a particular rifle.

Their location in not excessively deep and eutrophic waters favour an increase in biomass and the number of species thanks to the support and the protection offered by the solid substrates together with their vertical gradient given by their sticking up from the bottom and the enormous food availability in the form of already sedimented suspended organic material.Molin E., Fiorin R., Riccato F., Artico G., Campaci P., Comunità macrobentonica di tre substrati rocciosi del Golfo di Venezia (Nord Adriatico), Biologia Marina Mediterranea 16 (1), 2009: 278-279 Oases with extreme biologic richness with an increase in the number of species and also a considerable biomass per surface unit are thus formed. These areas are also extremely favourable for egg deposition, ogive-shaped capsules, larvae or reproductive forms which need a solid anchorage.

By increasing the wing chord and the leading edge droop, the wing cuff improved handling during approach and landing, while the wing-to-body fairing reduced the interference drag between the wing and the fuselage. Since the engines were new for this aircraft, a new engine pylon had to be designed. The lines of the cockpit have not changed but the fuselage was lengthened. In addition, the blend between the fuselage and the empennage was all new. While it appears as if area ruling was the intention of the blending, the blend design was really driven by attaching the original Learjet Model 35 empennage onto the larger Learjet Model 60 fuselage. The final aerodynamic improvements to the Model 60 included the creation of the distinctive "ogive" winglet trailing edge.

Guzmanes Tower,the Algaba The monumental face of La Algaba shows two main buildings, the Church of Santa Maria de las Nieves style Gothic-Mudejar and contains cross vaults and Tower of Guzman, with a height of 27 meters, was conceived as a defensive building beyond the 15th century. Three floors linked by stairs covered with vaults, the most interesting part from the stylistic point of view the set of windows: Reduced arc, ogive, lobed or multi-lobed. The auction castellated crown this well-preserved monument located in the traditional center of the core. The chapel of the Immaculate, in the neighborhood of the Aral, which was completely restored in 1929 and retains interesting sculptures like the Virgen de la Concepción, eighteenth century, and San Jose, which belongs to the school of Martinez Montanes.

Muggia provides many evident traces of its Venetian traditions and origin, as showed by the dialect, the gastronomic traditions, the gothic-venetian style of some houses, the devious "calli", the loggias, the ogive arches, the ancient coats of arms on the façades but mostly the main square, a true Venetian "campiello". Memories of its early ages include an important pre-historic "castelliere" on Mt. Castellier (S. Barbara) and Roman (Archaeological Park of Castrum Muglae) and medieval remains in Muggia Vecchia (Old Muggia), once one of the guarding castles that in the 10th century were built to defend the Istrian border against the invasion of the Hungars. The Castle of Muggia, destroyed in 1353 by the Triestines, retains several remains of the previous period such as the ruins of the walls.

It has been suggested this was either because it was now based on an otherwise unmodified A-4, or because the A-4 program had "national priority" by this time, and placing the development under the A-4 name guaranteed funding. A-4b used swept wings in order to extend the range of the V2 enough to allow attacks on UK cities in the Midlands or to reach London from areas deeper within Germany. The A-9 was originally similar, but later featured long ogive delta shaped wings instead of the more conventional swept ones. This design was adapted as a crewed upper stage for the A-9/A-10 intercontinental missile, which would glide from a point over the Atlantic with just enough range to bomb New York before the pilot bailed out.

Detonation of this shaped charge turns it into a highly focused stream moving forward at extreme speeds. Like medium and high velocity solid shot armour piercing projectiles, these warheads also cause spalling on the interior of the vehicle's armour plate.(solid shot AP projectiles also strike other items inside the vehicle and transfer very large amounts of kinetic energy to the object(s) struck) A problem with shaped charge warheads is that if the ogive shaped liner is deep, the warhead will have more penetration but will form a smaller hole; smaller holes are associated with less damage inside the armoured vehicle than larger ones. Research on shaped charge warheads has shown a hole that is the size of a large coin on the outside of a tank turret will have the diameter of a pencil lead on the turret's inner face.

Romanesque rotunda and palatium complex built by the Polish king Bolesław I Chrobry in the 11th century Aerial view of Przemyśl castle The location of Przemyśl castle and the earlier settlement lay on an important river crossing on a trade route running from the Black Sea to the Baltic Sea and through the Carpathian passes, and was a site of a fortified grod belonging to the Lendians (Lendizi), who were a West Slavic tribe descended from the White Croats. In 1018, the Polish king Bolesław I Chrobry recaptured Przemyśl and built a stone Romanesque rotunda and palatium complex. Later, Casimir III the Great was responsible for the building of a Gothic castle in 1340, of which only a gate in Ogive style survives to this day. The buildings were damaged by the invading Vlachs in 1498, and rebuilt once again for Piotr Kmita Sobieński.

Under the Aragonese dominion, more precisely of Alfonso V of Aragon (1442 - 1458), the hall was rebuilt by Guillem Sagrera who enlarged it the spaces and the dimensions. The hall is called the Hall of the Barons because around 1487 Ferdinand I of Naples invited some of the barons who had conspired against him to this place, with the excuse of celebrating his nephew's wedding. In reality this was nothing but a trap; the barons that were present were arrested and immediately put to death. Tower of the Beverello Located at the corner of the Tower of Beverello, between the northern side and the eastern side, facing the sea, the large room (26 m x 28 m) is covered by an octagonal vault resting on large angular ébrasement and equipped with sixteen ogive forming a star pattern with a bright oculus in the center.

To handle the aerodynamic heating issues, the fins were made of steel rather than aluminum, and featured cut-away sections to keep the rear portions of the surfaces out of the Mach cones, a feature they referred to as "mach tips". Work on Mk.4 was curtailed after 1956 as the RAE decided that the rapid closing speeds of two Mach 2+ aircraft would be so quick that the missile would have no chance to be launched while still within the range of its seeker. In August 1956, the Fleet Air Arm took over development of the Blue Jay line with Blue Jay Mk.5, replacing the IR seeker with a semi-active radar homing (SARH) system intended to be used with the De Havilland Sea Vixen's AI.18 radar with a special continual wave illuminator mode. This was otherwise identical to Mk.4, differing only by replacing its seeker section with a longer ogive nose cone holding the radar receiver antenna.

If, on the other hand, the ogive is shallow, it will have less penetration, but cause a larger hole on the inside which will result in a massive spalling.A rule of thumb for infantry antitank weapons is that if a HEAT warhead has to use more than two-thirds of its official penetration capability, it will have less effect on the interior of the vehicle. In 1954, during the siege of Dien Bien Phu, France had dismantled and flown in a number of M-24 Chaffee light tanks. Their thickest armor was only 25.4 mm. The Viet Minh's main infantry antitank weapon was the old World War Two U.S. 2.36-inch bazooka, captured from Nationalist Chinese forces and supplied by Communist China. During the siege the French launched counterattacks using the M-24 in support of their infantry. One Chaffee took seven hits from 2.36-inch bazookas and still continued to fight, demonstrating that portable rocket launchers were hardly a flawless tank-killer.John Keegan, "Dien Bien Phu", page 110, Ballantine Books, 1974 Other examples became evident during the Vietnam War.

Built of brick on a stone foundation and featuring additional elements of stone, the First Unitarian Church is a Gothic Revival building. Pilasters divide the facade into three bay, with the doorway in the center, and the side is divided into five. The left bay of the facade, from the perspective of a viewer on the street, is occupied by the base of a square tower nearly twice the height of the rest of the building; while shorter windows in the tower and facade sit below similar second-story windows, and the side windows occupy the height of both stories, tall third- story windows are set near the top of the tower, and the pilasters on all four corners of the tower, similar to those on the rest of the building, are crowned with pointed pinnacles. The building's general shape is that of a front-gable rectangle, with small-size crenellations atop the edges, and the Gothic Revival style is typified by the ogive windows and doorways in the facade and side.
