Lyulka AL-21
The Lyulka AL-21 is an air jet engine that was developed in the USSR by Archip Mikhailovich Lyulka from the early 1960s as the successor to the AL-7 and manufactured in large-scale production from 1967. Up to 1991, 5011 copies were built in Plant No. 45 in Moscow .
The standard version AL-21F-3 is a single-shaft jet engine with a 14-stage axial compressor with guide vanes that were adjustable in the 1st to 4th and 10th to 14th stages. The turbine blades of the first two stages of the three-stage turbine were cooled by diverted air from the compressor. The combustion chamber was a tubular ring combustion chamber with 12 nozzles.
