Tumansky R-13
The Tumanski R-13 is a twin- jet engine, which was manufactured in the USSR in large series.
History
The R-13 was developed between 1963-1966 by Sergei Alekseevich Gavrilov from the Tumanski R-11 and is also a two-shaft turbojet. For this purpose, the engine with a new five -stage high pressure compressor, a new combustion chamber ( which improves the restarting of the engine at high altitude ) and a new afterburner with a combination of star and circular flame stabilizer was fitted. Furthermore, titanium components were more widely used. It is the MiG -21 and Sukhoi Su -15 used in different versions, so in the MiG -21M, MF, SM and SMT and the Sukhoi Su- 15M and TM. The R-13 is being built in China as well as WP -13 and experienced a similar fate as the Tumanski R- 11th Originally both were to be built in China under license, but due to the Sino-Soviet split, the license and the technical support was withdrawn. Under the direction of chief designer Jiang Hepu the Chinese managed the successful reconstruction of both engines, where the term WP -7 and WP -13 was given. In the MiG -21bis, the R- 13 was later replaced by the more powerful Tumanski R -25.
