The SNECMA M53 is an afterburning turbofan engine developed for the Dassault Mirage 2000 fighter by Snecma . The engine is in service with different air forces, including the latest Mirage 2000-5 and 2000-9 multirole fighters.
6-566: The engine was derived from the Atar series by adding a bypass duct aft of the 3rd compressor stage. The first 3 stages were enlarged to give an LP and HP section on the same shaft. It is a single shaft turbofan, or continuous bleed/bypass turbojet. It was originally called the Super Atar 9K50 and was designed for sustained flight at Mach 2.5. Flight testing started in July 1973 using a Caravelle flying test-bed and
12-538: Is in service in 8 different air forces, powering the whole Mirage 2000 family of airplanes, including the latest Mirage 2000-5 and 2000-9 multirole fighters.

Production of the Eland ceased in 1961 when the Napier company was taken over by Rolls-Royce . The Eland
18-627: The Napier Eland turboprop and then later in a big way with the Pratt & Whitney JT9D engine. Modular construction allows sub-assemblies or modules to be changed without the need for full power testing of the engine after replacement. Modules are changed “on condition” by monitoring deteriorating trends in performance and mechanical measurements, such as exhaust gas temperature and oil samples, and by visually assessing blade clearances and high temperature distress on internal parts using borescopes. The engine
24-563: The civil Convair CV-540 . The military and civil operators had perpetual trouble with the engines which were considered complex. Due to their unreliability The Department of Transport reduced the time between overhauls . The CC-106 had its Elands replaced with the Allison T56 turboprop and the CV540 was re-engined with the Pratt & Whitney R-2800 Double Wasp piston engine. Potential production applications which were subsequently cancelled were
30-481: The engine first went supersonic in a Mirage F.1 test bed at the end of 1974. The engine was designed to have better performance than the latest Atar engines but simpler and less costly than the SNECMA TF 306 turbofan. The fan and HP compressor on the same shaft gave an engine with no restrictions on throttle movements, known as 'carefree handling', during flight. The engine has a modular construction, first introduced on
36-585: Was first tested in flight in 1953 in a Vickers Varsity aircraft. Further flight proving was carried out from 1955 using the first production Airspeed Ambassador 2. The Eland was dropped from production when Napier was acquired by Rolls-Royce Limited in 1961. The only production applications for the engine were two variants of the Convair CV-240 family , the Royal Canadian Air Force Canadair CC-109 Cosmopolitan and
