The D-30F6 engine features a two-shaft configuration with exhaust mixing from both ducts. The engine consists of seven modules. It has a low-pressure five-stage compressor, a high-pressure ten-stage compressor and a cannular combustion chamber. The low- and high-pressure turbines are two-staged. The nozzle vanes and highpressure turbine rotor blades are cooled. The afterburner houses the exhaust mixer and has four ring flame stabilisers. The multivane supersonic nozzle is cooled.
The engine design enables onboard parameter monitoring. Reliability of the engine is ensured by the protection, backup, and early malfunction detection systems. The electro-hydraulic engine control system is backed up with the hydraulic system activated if the electronic one has failed to ensure flight safety and effective mission accomplishment. The engine has unique altitude and airspeed performance, providing maximum airspeed of 3,000 km/h at altitude and 1,500 km/h near ground. The D-30F6 engine is designed to power the MiG-31E fighter/interceptor.
