D-36, series 4A

The D-36, Series 4A, engine is designed to be installed in the civil, cargo and passenger airplanes.
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.

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).
