The Soloviev D-30 is a Soviet two-shaft low-bypass turbofan engine, officially referred to as a "bypass turbojet." A supersonic afterburning version, the D-30F6, is used in the Mikoyan-Gurevich MiG-31 interceptor, while the non-afterburning civilian versions, the D-30Kp and D-30KU are used in the Ilyushin Il-62M and Tupolev Tu-154M airliners, and in the Ilyushin Il-76MD, TD heavy cargo aircraft.

Design and development[edit]

In the mid-1970s, the Soviet Union began the search for a high-speed interceptor to supplement and replace its MiG-25. The Mig-25 had two enormously powerful Tumansky R-15 turbojets, allowing Mach 3 speed at high altitudes, but the problem was their weak performance at low altitudes, not even sufficient to cross Mach 1 boundary. More acute problems stemmed from the tendency of the Foxbat's engines to break down at maximum throttle in high-speed situations.[1] A new engine, this time a low-bypass turbofan, was needed to power the new interceptor. The Mikoyan-Gurevich (MiG) design bureau contracted OKB-19 design bureau (now part of Aviadvigatel) to build such an engine, for the aircraft that would become known as the MiG-31.

Aviadvigatel came up with the D30-F6 turbofan. Capable of generating 9,500 kgf (20,900 lbf or 93 kN) dry thrust and 15,500 kgf (34,200 lbf or 152 kN) afterburning thrust, the engine gave MiG's new fighter a top speed exceeding 1,800 mph (2,900 km/h), and a maximum takeoff weight of 101,000 lb (45,800 kg). These powerful engines also allowed the large and complex fighter to attain supersonic speeds at low altitudes under 5,000 feet (1,500 m).

Applications[edit]

The D30-F6 is used on a variety of Russian, Chinese, and other Easter European airliner and military transport designs. The massive Aviadvigatels have only been used in two aircraft designs: the MiG-31 Foxhound, and the experimental Sukhoi Su-47 Berkut (formerly S-37).
