Progress D-436
The Ivchenko Progress D -436 is a three-shaft turbofan engine with high bypass ratio by the Ukrainian producer Ivchenko (English Ivchenko Progress).
The development of this as a replacement for the D -36 and for the use of Tu -334, Be-200, An-148 and Yak- 42D -100 provided the engine was started at the beginning of the 1990s.

The first aircraft Tu- 334 lifted with this engine off on 8 February 2000, after which a short time later, the approval by the Russian air traffic control authority.
The engine has a one-stage fan, which is driven by a three-stage turbine, and a booster stage. Of the six-stage low-pressure compressor is driven by a single stage low pressure turbine. The seven-stage high-pressure compressor is driven by a single stage high pressure turbine. Additional facilities include a combustor with 18 fuel injectors, a reverse thrust system and partly electrically and partly hydro -working control system and an electronic monitoring and diagnosis system to the engine.
