The SNECMA M53 is a turbofan engine from the French manufacturer SNECMA . It serves as the drive for the Dassault Mirage 2000 .
history
The design of the M53 is based on the knowledge gained with the SNECMA Atar . It is a single-shaft engine with a 3-stage fan, a 5-stage axial compressor, an annular combustion chamber , a two-stage axial turbine and an afterburner . The main design goals included ease of maintenance and operation. The engine is modular and has electronic monitoring.
The first preliminary considerations took place between 1967 and 1968. They led to the development decision. The engine was initially called Super Atar . In February 1970 the first was put to the test. The second prototype was completed in August. A thrust of 51 kN was achieved in October. The tests with the afterburner began in November 1970. In the first acceptance runs in May 1971, 54.9 kN were achieved dry and in a 50-hour run with the afterburner 81.39 kN were achieved. In December 1971, the first simulations were carried out as part of the expected mission profile. The flight tests in a Sud Aviation Caravelle began on July 18, 1973. For tests in the supersonic range, a converted Dassault Mirage F1 was used from December 1974 . The official proof of performance over 50 hours was provided in July 1977 with 88.5 kN. A total of 20 prototype engines were produced.
The first production version was the M53-2, which was intended for the Mirage F1-M53 and the prototypes of the Dassault Mirage 4000 and the Dassault Mirage 2000 . The thrust was 83.4 kN with an air throughput of 84 kg / s and a speed of 10200 min-1.
For the serial production of the Mirage 2000, the speed of the turbine could be increased somewhat. This version was given the designation M53-5. It produced an afterburner thrust of 88.21 kN at a speed of 10500 min-1 and was manufactured between 1980 and 1985. This was followed by the M53-7, which was later called the M53-P2, with further increased performance, and series production began in 1984. It was intended for the Mirage 2000N and equipped with a modern FADEC . This version was also used in the Mirage 2000-5 and Mirage 2000-9.
Production was stopped in 2005 after 639 engines were built. SNECMA will remain responsible for parts supply until 2030 and will continue to develop individual components.
