The Lyulka AL-7 was a turbojet designed by Arkhip Mikhailovich Lyulka and produced by his Lyulka design bureau. The engine was produced between 1954 and 1970.
The AL-7 had supersonic airflow through the first stage of the compressor. TR-7 prototype developing 6,500 kgf (14,330 lbf, 63.7 kN) of thrust was tested in 1952, and the engine was initially intended for Ilyushin's Il-54 bomber. The afterburning version AL-7F was created in 1953. In April 1956, the Sukhoi S-1 prototype equipped with AL-7F exceeded Mach 2 at 18,000 m (70,900 ft), which led to production of Su-7 'Fitter' and Su-9 'Fishpot' equipped with this engine. Later, the engine was adopted for 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.
