avco lycoming t53 tuRbo shaft engine
Development of what became the T 53 turbine engine was commenced by Avco Lycoming in 1951. In 1953 the research and development produced an experimental turbo shaft engine, T 53 of 600shp that in 1956 was selected to power a Bell experimental helicopter that in turn developed into the UH-1 Iroquois "Huey".
In excess of 19,000 T 53 engines of several variants have been built since production commenced accumulating some 50 million flight hours. Most of the engines have powered helicopters such as the Bell Iroquois series, the Bell AH-1 Huey Cobra series, Bell 204 and the Kaman HH-43F.
Several turboprop versions were built, one of which powered the Grumman OV-1 Mohawk aircraft.
Six of the 1,100shp T53-L-11 variants made up the engine family that became the most widely built and used of the series until being finally superceded by the more powerful T53-L-13 engine in 1966.
