The Soloviev D-30 (now the Aviadvigatel PS-30) is a Soviet two-shaft low-bypass turbofan engine, officially referred to as a "bypass turbojet".

Design and development[edit]

The original version of the Soloviev D-30 was developed to power the Tupolev Tu-134 short-to-medium range jet airliner, and had specifications similar to those of the original Pratt & Whitney JT8D.

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.[citation needed] 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.

The Soloviev design bureau came up with the D-30F6 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 3,000 km/h (1,900 mph),[citation needed] and a maximum takeoff weight of 45,800 kg (101,000 lb). These powerful engines also allowed the large and complex fighter to attain supersonic speeds at low altitudes under 1,500 m (4,900 ft).

More powerful civilian versions of the D-30 were also developed with an increased bypass ratio: this is comparable to Pratt & Whitney's development of the JT8D-200 series, but with even an greater increase in thrust. This development process gave rise to the D-30KP, which powers the Ilyushin Il-76 heavy cargo aircraft, and the D-30KU used in the Ilyushin Il-62M and Tupolev Tu-154M jet airliners.

The D-30 is used on a variety of Russian, Chinese, and other Eastern European airliner and military transport designs, such as the Xian Y-20, added to China's military fleet in July 2016. The D-30 engines have only been used in two fighter aircraft designs: the MiG-31 Foxhound, and the experimental Sukhoi Su-47 Berkut (formerly S-37).
