D-36, Series 4A
The engine is used for transport and convertible passenger/cargo aircraft. The D-36, Series 4À, engine is a bypass turbofan engine featuring a thrust reverser and noise suppression. The takeoff thrust is 6,500 kgf.
The multi-purpose engine mount makes it possible to use the engine in numerous types of aircraft without changing the engine design by installing the engine under or above the wing, in the aircraft fuselage or on its both sides. |

Main advantages of the engine:
- low specific fuel consumption;
- high degree of reliabilitye;
- 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).
