The engine was further developed with greater power and used in the later twin- engined Dassault-Breguet Atlantique long-range reconnaissance aircraft; also in the Canadair CL-44 and Transall C-160 transport aircraft. A single stage HP turbine drives the nine-stage HP compressor. A three-stage LP turbine drives the six-stage LP compressor and, through a reduction gearbox, the propeller. The combustor is cannular.

This was done by replacing the multiple individual chambers with a single annular casing with individual flame tubes or cans known as cannular. The pressure ratio was increased and variable inlet guide vanes fitted to prevent low-RPM problems (rotating stall/blade flutter) with the higher design pressure ratio. A 2-stage turbine was required. A low boost (10% at take-off) afterburner was fitted.

Two bearings gave a further advantage: previous engines had also needed a coupling in the shaft to allow for any misalignment between the static parts of the three bearings. With two bearings, the shaft simply followed the straight line between them. So the introduction of the large diameter tube allowed the removal of a bearing, a coupling, the engine's support structure for that bearing together with its lubrication system and cooling air supply. A cannular combustor was used with seven flame tubes.

Gas-flow diagram of Olympus Mk 101 The first engine, its development designation being BOl.1 (Bristol Olympus 1), had six LP compressor stages and eight HP stages, each driven by a single-stage turbine. The combustion system was novel in that ten connected flame tubes were housed within a cannular system: a hybrid of separate flame cans and a true annular system. Separate combustion cans would have exceeded the diameter beyond the design limit, and a true annular system was considered too advanced.Baxter 1990, p.

It also powered the Antonov An-22 Antei (with NK-12MA), the world's largest aircraft at the time, and several types of amphibious assault craft, such as the A-90 Orlyonok "Ekranoplan". The engine has a 14-stage axial-flow compressor, producing pressure ratios between 9:1 and 13:1 depending on altitude, with variable inlet guide vanes and blow-off valves for engine operability. The combustion system used is a cannular-type: each flame tube is centrally mounted on a downstream injector that ends in an annular secondary region. The contra- rotating propellers and compressor are driven by the five-stage axial turbine.

The original version of the Soloviev D-30 or Solowjow D-30 was developed to power the Tupolev Tu-134 short-to-medium range jet airliner, and had specifications similar to those of Western analogues such as Pratt & Whitney JT8D. D-30 is a two spool, low bypass turbofan gas turbine engine specifically designed for short-haul passenger aircraft Tu-134, however, it also served as a base for the development of a family of advanced engines. Engine development was started in the early 60's. Nevertheless, by 1966, the engine was put into serial production. The D-30 engine has a two stage compression spool, a cannular combustion chamber and a 4-stage turbine. D-30 was the first engine in the Soviet engine-building industry to use cooled turbine blades.
