Design and development
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 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.[2][clarification needed] 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.

АЛ-7 — турбореактивный двигатель, разработанный под руководством Архипа Михайловича Люльки и производившийся на заводе № 165 в Москве. На первой ступени компрессора поток воздуха движется со сверхзвуковой скоростью. Прототип двигателя, обозначавшийся ТР-7 и производивший 6500 кгс или 63,7 кН тяги был испытан в 1952 году. Изначально двигатель предназначался для бомбардировщика Ил-54.Другой контент может иметь иную лицензию.
