Soloviev D-30 - WikiHQ

The Soloviev D-30 (now the Aviadvigatel PS-30) is a Soviet two-shaft low-bypass turbofan engine, officially referred to as a "bypass turbojet". It is one of the most powerful turbofan engines developed in the Soviet Union. Development of the turbofan spurred numerous growth versions with increased fan diameter and modified component arrangements. Developed in a short period of time (about three years), the D-30 turned out to be one of the most reliable engines in the history of Soviet engine development, and it was recognized with the USSR State Prize.

Design and development

The original version of the Soloviev D-30 was developed specifically to power the Tupolev Tu-134 short-to-medium range jet airliner; however, it also served as a base for the development of a family of advanced engines. Engine development was started in the early 60s. By 1966, the engine was put into serial production.

Similar to the D-30KU, a new engine variant called D-30KP which delivered 12,000 kgf of thrust was developed for military transport aircraft Il-76. The development was completed by the end of the 60s. In 1971, Il-76MD with the propulsion unit on the basis of four D-30KP was demonstrated to the country’s leaders. In 1972, engine passed certification tests and then was presented to the public at the next international air show in Le Bourget (France). By 1974 the engine was put into service to power not only military Il-76 itself, but also numerous modifications: tanker plane Il-78, “aircraft-hospital” Il-76MD Scalpel, early warning and control aircraft A-50, weightlessness simulator Il-76K, airborne test rig Il-76LL for in-flight tests of the aircraft engines and others. D-30KP was identical to its predecessor D-30KU - both are low bypass turbofan engines. The engine differs only by having a higher gas temperature at the turbine inlet and an increased compressor pressure ratio and bypass ratio. Powered by four D-30KP engines, Il-76 is capable of lifting a payload of 40 tons (88,000 lb) over a range of 5,000 km (2,700 nmi; 3,100 mi) at cruise speed up to 900 km/h. D-30KP engines were manufactured in the city of Rybinsk (Yaroslavl region) at Rybinsk Engine Production Plant (now NPO UEC-Saturn). The D-30KP engines production continues till present for military supplies. More than 4700 D-30KP engines have been manufactured in total.

The Chinese Xi'an Y-20 prototype was also powered by four D-30KP-2 engines.

;D-30KU-154:

The successful replacement of the engines on long-haul Il-62 stimulated the leaders of the Ministry of Aviation Industry in the Soviets to re-engine another popular aircraft – the medium-haul passenger airliner Tu-154. Ultimately, Tu-154M powered by D-30KU-154 was the backbone of the civil aviation industry in the Soviets till the end of the 20th century. The D-30KU-154 engine was developed with a maximum thrust of 10,500 kgf specifically to power the Tu-154. Development started in 1979. Pavel Solovyov used the D-30KU core as a starting point. In the course of designing the D-30KU-154 engine, some of the systems were improved, new components were added, and in 1984 the new engine entered serial production. The replacement of Kuznetsov NK-8 engine with the D-30KU-154 engine on Tu-154 allowed the reduction the fuel consumption by 28%! This ultimately defined the profitability of the air transportations industry in the Soviets for another 15 years. During the years of active operation of D-30KU-154, the manufacturer, Perm design bureau, continued working on improving the engine. A vivid example of that is the development of the noise suppression system with noise-absorbing structures from polymer composite materials. There were in total more than 1500 D-30KU-154 engines manufactured by Rybinsk Engine Plant (now NPO UEC-Saturn). Jane's all the World's Aircraft 1993–94
