Lyulka AL-7

from Wikipedia, the free encyclopedia

The Lyulka AL-7 is an air jet engine that was developed in the USSR by Archip Michailowitsch Lyulka and manufactured in large series as the successor to the not fully developed Lyulka AL-5 .

The prototype was tested in 1952 and was originally planned for the Ilyushin Il-54 bomber. The afterburner version AL-7F was developed in 1953. In 1957 the engine was installed in the Sukhoi Su-9 , with which the aircraft reached Mach 2 at an altitude of 18,000 meters. The engine was adapted for the Tu-128P in 1960. It is a single shaft engine with a nine-stage axial compressor and a two-stage turbine.
