D-30F6 military turbofan engine

D-30F6The D-30F6 engine is an augmented, bypass, two-shaft turbofan with a common afterburner and variable supersonic nozzle intended to power the MiG-31 supersonic fighter-interceptor. 

Two engines with separate air intakes provide thrust for the airplane.
OJSC Aviadvigatel developed product.

The engine has a unique altitude-speed performance, providing 3000 km/hour (maximum) speed of the airplane and 1500 km/hour ground speed.
The high performance of the engine allows the MiG-31 airplane to have perfect maneuverability, large range and significant superiority during flight operation.


Reliability of the engine is provided by protection, back-up and diagnostics systems:

  • low pressure rotor maximum speed limitation system and maximum turbine exit temperature limitation system;
  • safety system against turbine overspeed (drive of constant revolutions);
  • anti-icing system for the cowl and blades of inlet guide vanes;
  • anti-surge system.

Electronic-hydraulic system of automatic engine control is duplicated by hydraulic system ensuring safety of flight and back-up function in case of electronic system malfunction.

The design of the engine provides an opportunity of the parametric control of its condition aboard of the airplane.

To evaluate the condition of the air and gasflowpath parts in service, the engine design provides for the inspection of all compressor and turbine blades, and also, nozzle vanes of both high pressure turbine stages.

In case of foreign objects ingestion into the engine, the design allows to replace in service separate damaged blades of the 1-st high pressure compressor stage and the entire module of low pressure compressor


The long-term D-30F6 engine experience on the MiG-31 supersonic airplane has shown high reliability of the engine in various climate conditions and excellent performance retention within life time.
