A French engine for supersonic combat aircraft, derived from a German World War II design.
The basis for creating the ATAR engine was the German BMW 003 engine. Its designer, Hermann Ostrich, was employed by the French, and under his leadership, development work on larger and more powerful engines based on the BMW 003 design began at the former Dornier factory in Rickenbach, in the French occupation zone of Germany. The design office was given the name ATAR (an abbreviation of Atelier Technique Aeronautique Rickenbach).
The preliminary design of the ATAR 101 engine was completed in October 1945, and the first ATAR 101 was started in March 1948. ATAR 101 engines were used in the Dassault Super Mystere fighter-bomber aircraft. Subsequently, the ATAR 08 and 09 versions were developed, which were similar in size to the 101 but were significantly redesigned — a nine-stage compressor replaced the seven-stage one, a two-stage turbine was used, and the afterburner was improved. As a result, thrust was significantly increased.
The presented 09C version, used in the Mirage III fighter and Mirage V ground-attack aircraft, was introduced in 1959. The engine is started using compressed air generated by a starter located in the cone in front of the air intake.
