The D-18T engine was selected in 1984 to power world mightiest transport planes - An-124 Ruslan and An-225 Mria.

The advantages of the engine:

Three-shaft modular engine became a base model for entire line of XXI century aircraft engines with static thrust up to 30t. Gas dynamic quality and high thermal cycle parameters of the D-18T allow to use it as a heart of gas turbine installations with shaft power of 25 to 30MW.

Engine Modules:
  • Fan fairing
  • Fan wheel
  • Fan shaft with bearing
  • Fan casing
  • Fan stator blades
  • Intermediate pressure compressor
  • Main module
  • Thrust reverser
  • Combustion chamber
  • HP turbine rotor
  • Turbine bearing cases
  • IP turbine rotor
  • Fan turbine
  • Rear bearing assembly
  • Rear mount
  • Exhaust cone
  • Exhaust nozzle
  • D-18T engine is manufactured by the Zaporozhye Motorostroitel Industrial Association in cooperation with ZMDB "Progress".
