Tumanski R-13

from Wikipedia, the free encyclopedia

The Tumanski R-13 is a twin-shaft jet engine that was mass-produced in the USSR .

history

The R-13 was developed between 1963 and 1966 by Sergei Alexejewitsch Gawrilow from the Tumansky R-11 and is also a twin-shaft turbojet. To do this, the engine was equipped with a new five-stage high pressure compressor , a new combustion chamber (which improves the restart of the engine at great heights) and a new afterburner with a combination of star and circular flame stabilizers. Titanium components were also used to a large extent . It is used in different versions of the MiG-21 and Sukhoi Su-15 , such as the MiG-21M, MF, SM and SMT and the Suchoi Su-15M and TM. The R-13 is also built in China as the WP-13 and experienced a similar fate as the Tumanski R-11. Originally both were to be built under license in China, but due to the Soviet-Chinese split, the license and technical support have been withdrawn. Under the direction of chief designer Jiang Hepu, the Chinese succeeded in reproducing both engines, which were given the designation WP-7 and WP-13. In the MiG-21bis, the R-13 was later replaced by the more powerful Tumanski R-25 .
