Summary

edit
Description In response to an Air Force request in 1952 for a 500- to 700-horsepower turboprop engine, Lycoming produced two designs, both of which could be converted to turboshafts to power helicopters by removing the propeller gearbox. Lycoming was awarded a contract to develop a free-turbine turboshaft engine, designated LTC1 (military designation T53-L1). It was military qualified in 1958 and the first production engine was delivered in 1959. The front drive, concentric-shaft design became a widely accepted U.S. standard for turboshaft engines. The T53 gave Lycoming its start and played a key role in the expansion of the Army%u2019s airmobile role during the Vietnam War. The T53 was used on the Bell UH-1 Iroquois (Huey) and AH-1 HueyCobra helicopters and the Grumman OV-1 Mowhawk airplane.
