D-36, Series 4A
The D-36, Series 4A, engine is designed to be installed in
the An-74TK-300 passenger airplane.
High quality and reliability of this engine are ensured
by the perfect design of the base D-36, Series ЗА, engine
and high degree of mastering of the series production
process.
Ease of the engine maintenance and possibility to perform
its profound 'on-wing' diagnostics permit reliable
on-condition operation of this engine.
Main advantages:
- low specific fuel consumption;
- high degree of reliability;
- long service life;
- low level of noise and harmful matter emission;
- ease of maintainability and high level of repairability ensured by the engine modular design;
- engine mount design permitting to install the engine at an underwing pylon;
- availability of thrust reverser;
- all-weather and all-climate design of the base An-74 airplane makes it possible to operate the An-74 TK-300 model in various climatic conditions, and availability of the emergency power condition permit the airplane to take off from high-altitude airfields (H=4000 m).
