Contents

Development

Development of the NK-4 began on September 27, 1955 [1] at the Kuznetsov Design Bureau. Factory tests were passed on April 17, 1956 [1] and state tests were passed in 1957. [1] At the time, the NK-4 was considered an economical and technologically advanced engine. [1]

A modified version of the NK-4 that improved in terms of service life and efficiency, [1] the NK-4A, passed factory tests in October 1957. [1] State tests of the NK-4A were passed in June 1959. [1]

The Ilyushin Il-18 is a large turboprop airliner that first flew in 1957 and became one of the best known and most durable Soviet aircraft of its era. The Il-18 was one of the world's principal airliners for several decades and was widely exported. Due to the aircraft's airframe durability, many examples achieved over 45,000 flight hours and the type remains operational in both military and civilian capacities. The Il-18's successor was the long range Il-62 jet airliner.

The Tupolev Tu-85 was a Soviet prototype strategic bomber based on the Tu-4, an unlicensed, reverse engineered copy of the Boeing B-29 Superfortress. It was the ultimate development of the B-29 family, being over 50% heavier than its progenitor and had nearly double the range. Only two prototypes were built before the program was cancelled in favor of the turboprop powered Tupolev Tu-95 bomber which could cover the same range at a far higher speed.

The Kuznetsov NK-12 is a Soviet turboprop engine of the 1950s, designed by the Kuznetsov design bureau. The NK-12 drives two large four-bladed contra-rotating propellers, 5.6 m (18 ft) diameter (NK-12MA), and 6.2 m (20 ft) diameter (NK-12MV). It is the most powerful turboprop engine to enter service.

The Tupolev Tu-95LAL was an experimental aircraft that was a modified Tupolev Tu-95 Soviet bomber aircraft, which flew from 1961 to 1965, analogous to the United States' earlier Convair NB-36H. It was intended to see whether a nuclear reactor could be used to power an aircraft, primarily testing airborne operation of a reactor and shielding for components and crew. The reactor did not actually power the aircraft.

The Ilyushin Il-16 was a Soviet lightweight armored ground-attack aircraft developed at the end of World War II by the Ilyushin Design Bureau. It was in essence a scaled-down version of the Ilyushin Il-10, but was fitted with a newly developed Mikulin AM-43 engine with the expectation that it would be faster and more maneuverable than its predecessor. However, the engine's defects proved to be impossible to rectify and further development were canceled in mid-1946.

The Ivchenko AI-20 is a Soviet turboprop engine developed by the Ivchenko design bureau in the 1950s. It has been built in large numbers, serving as the powerplant for both the Antonov An-12 transport and the Ilyushin Il-18 airliner.

The Ilyushin DB-4 or TsKB-56 was a Soviet twin-engined bomber aircraft of the early 1940s. It was a development of the Ilyushin DB-3 and was intended as a replacement for the earlier aircraft, but only two prototypes were built; engine problems and the need to concentrate production on existing types following the German invasion of the Soviet Union in June 1941 meant that no more examples were built.
