D-30KU-154

Bypass Turbofan Engine

The successful replacement of the engines on long-haul Il-62 stimulated the leaders of the Ministry of Aviation Industry of the USSR to re-engine another popular aircraft – medium-haul passenger airliner Tu-154. As a result, Tu-154M powered by D-30KU-154 was the backbone of the civil aviation in Russia for 15 years at the end of the 20th century.

The development of the D-30KU-154 engine with the maximum thrust of 10 500 kgf for powering Tu-154 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 units were added, and in 1984 the new engine entered serial production. Replacement of NK-8-2 from Samara with the D-30KU-154 engine allowed to reduce the fuel consumption by 28% what defined the profitability of the air transportations for the coming 10-15 years.

For many years the D-30KU-154 engines were used as part of the propulsion units of medium-haul passenger aircraft not only of the domestic airlines, but of the government airliners of some of the countries.

During the years of the D-30KU-154 active operation, the specialists of the Perm design bureau continued their patient work 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).

Medium-Haul Passenger Aircraft Tu-154M

Winged vehicles similar to Tu-154M, seldom come into being. For 15 years, since the 80s of the 20th century, this liner continued to be the most widespread airplane of the domestic civil aviation, and flew to all cities of the Soviet Union. The Tu-154 airplanes flew to more than 80 cities of the world, and were many times demonstrated at prestigious air shows and exhibitions.

Andrey Tupolev’s Design Bureau started to develop the basic model of Tu-154 in 1963. The new liner was supposed to combine the best characteristics of its predecessors: Tu-104 had the highest cruise mode, Il-18 had the longest flying distance, An-10 was notable for its take-off and landing parameters.

The process of constructing the Tu-154 prototype was completed in 1966, when it was equipped with the propulsion unit on the basis of the NK-8-2 engines developed by Nikolai D. Kuznetsov. In 1972, Tu-154 makes its first regular flight from Moscow to Mineralnye Vody, bringing there 160 passengers in less than two hours. The task of reaching the maximum cruise speed as compared with that of the similar aircraft (up to 950 km/hr) – was accomplished.

In 1982, Tu-154M makes its first flight. This was a new version of the airliner equipped with Pavel Solovyov’s engines. The flight tests confirmed economic efficiency of the liner modernization. With regard to the comfort level, Tu154M was as good as its contemporaries, and with regard to environmental noise, Tu-154M fully complied with all the world’s standards in force.

The serial production of passenger airliners Tu-154M was started in 1984. Since that time more than 300 airliners were manufactured, including 100 airliners for exporting.
