The R-13 turbojet engine is a direct development of the R-11 engine, which was commonly used in MiG-21 aircraft. The engine was modernized under the supervision of S. Gawryłów. The aim of the modernization was to reduce fuel consumption, increase thrust and, above all, improve overall parameters.

The history of Ivchenko’s aircraft engines began in 1945, at the Ukrainian CCCP in Zaporizhia. At that time, the OKB-478 design office and experimental plant were organized. The task of the OKB-478 office was to develop aircraft engines for airplanes and helicopters as well as other machines and devices for industry. The office was headed…

Information on Bristol Olimpus and General Electric J57 engines penetrated the CCCP. In 1952-1954, the Moscow Aviation Institute made aerodynamic calculations for a turbojet engine with a system of two shafts (propellers, spools). The calculations were carried out to achieve the speed of Ma 2 by the future aircraft. The main difficulty was to create…

Movable aerodynamic blades of the compressor stator was one of the ways to improve the operation of the turbojet engine. General Electric has been considering for almost a year – Which concept to choose? In 1952, it was decided to use movable steering wheels. With this arrangement, it was easier to develop lubrication and sealing…

An important engine in the CCCP was the AL-7 F-1 engine, which in Archip M. Lulka’s team was called TRD-31. The engine was created at the beginning of the 50s, through the development of the AL-5 engine, especially its enlargement. The AL-7 engine was first launched in September 1952. The AL-7 engine was used to…

Aleksander Mikulin, in addition to the large AM-3 engine, also developed the AM-5 engine with a lower power. This task resulted from the collapse of the TR-3 engine program, which had high hopes. The fall of the TR-3 engine program also plunged airframe programs, including the supersonic Su-17 (the first program with such a designation).…

The number of new CCCP turbojet designs in the period 1946-1947 was large. However, they all had a major disadvantage – the extremely short flight time, and therefore a short range. Even for the frontline planes, these parameters were difficult to accept. In the UK and the US, the performance was much better. Therefore, in…

During World War II, the CCCP paid little attention to the development of turbojet engines. The breakthrough came at the end of the war, when the Russians obtained several copies of the German Junkers Jumo-004 and BMW-003 engines, and some of the results of the experiments. Stalin ordered these engines to be copied and to…
