D-36 Series 4a Turbofan Engine

The D-36, Series 4A, engine is designed to be installed in the An-74TK-300 airplane.
High quality and reliability of this engine are ensured by the perfection of design of the base D-36, Series 3A, engine and high degree of mastering of the series production process.
Ease of the engine maintenance and possibility to perform its profound ‘on-the-wing’ diagnostics permit reliable on condition operation of this engine.

  Basic merits of the engine:
- 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 repair ability 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-74TK-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)
