The Lyulka AL-7 was a
turbojet
The turbojet is an airbreathing jet engine which is typically used in aircraft. It consists of a gas turbine with a propelling nozzle. The gas turbine has an air inlet which includes inlet guide vanes, a compressor, a combustion chamber, an ...

, was tested in 1952, and the engine was initially intended for
Ilyushin's
Il-54 bomber. The afterburning AL-7F version was created in 1953. In April 1956, the
Sukhoi S-1 prototype, equipped with the AL-7F, exceeded
Mach 2 at 18,000 m (70,900 ft), which led to the production of the
Su-7 'Fitter' and
Su-9 'Fishpot', equipped with this engine.
[Green, William and Gordon Swanborough. ''The Great Book of Fighters.'' St. Paul, Minnesota: MBI Publishing, 2001. .] Later, the engine was adopted for the
Tu-128 'Fiddler' in 1960, and for the
AS-3 'Kangaroo' cruise missile. The
Beriev Be-10 jet
flying boat used a non-afterburning AL-7PB with
stainless steel compressor blades.
Variants
;AL-7:Non-afterburning military turbojet.
;Al-7F: Afterburning versions of the AL-7F, typically, the AL-7F1-100 used in the
Sukhoi T-49.
