Snecma M53

The SNECMA M53 is a turbofan engine of the French manufacturer SNECMA. It serves the Dassault Mirage 2000 as a drive.

History

The design of the M53 is based on the findings that had been obtained with the SNECMA Atar. It is a Einwellentriebwerk with a 3-speed fan, a 5-stage axial compressor, an annular combustion chamber, a two-stage axial turbine and an afterburner. Among the most important design objectives included easy maintenance and easy operation. The engine is modular and has an electronic monitoring.

First Preliminary took place 1967-1968. They led to the development decision. The engine initially was named Super Atar. In February 1970, the first ran to the test. The second prototype was completed in August. In October, a thrust of 51 kN was achieved. The experiments with the afterburner started in November 1970. During the first loss runs in May 1971 were 54.9 kN dry and achieved in a 50h run with afterburner 81.39 kN. In December 1971, initial simulations were carried out in the framework of the expected mission profile. The flight tests in a Sud Aviation Caravelle began on 18 July 1973. For experiments in the supersonic range was from December 1974, a Dassault Mirage F1 converted. The official performance records 50h was performed in July 1977 at 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 Dassault Mirage 2000 and the. The thrust was 83.4 kN at an air flow rate of 84 kg / s and a rotational speed of 10200 min -1.

For the series production of the Mirage 2000, the speed of the turbine could be increased somewhat. This version was given the designation M53 - fifth It supplied a Nachbrennerschub of 88.21 kN at a speed of 10500 min -1 and was manufactured between 1980 and 1985. This was followed by continued increases in performance execution M53 -7, which was later called M53 -P2, and their serial production began in 1984. She was scheduled for the Mirage 2000N and equipped with a modern FADEC. Also in the Mirage 2000-5 Mirage 2000-9 and this version was used.

The production was discontinued after 639 engines built in 2005. SNECMA is responsible for the supply of parts to 2030 and developed individual components on.
