The Lycoming T53, (company designation LTC-1) is a turboshaft engine used on helicopters and (as a turboprop) fixed-wing aircraft since the 1950s. It was designed at the Lycoming Turbine Engine Division in Stratford, Connecticut, by a team headed by Anselm Franz, who was the chief designer of the Junkers Jumo 004 during World War II.
It is used to power newer Sikorsky S-92/H-92 helicopters. The CT7-8A1 produces 2,520 shp. CT7-8A5; CT7-8A7: Developed by GE as an uprated, more efficient and more reliable version of the CT7-8A1 engine for the Royal Canadian Air Force's Sikorsky CH-148 Cyclone helicopters. It is the most modern version of the CT7/T700 engine family.
These studies culminated in the testing of the first prototype engine, designated YT63-A-3, in April 1959. [1] In 1960, the US Army settled for a rotary wing platform. The YT63-A-3 first flew in a variant of the Bell 47 helicopter in 1961. A modified version of the engine (YT63-A-5) with the exhaust pointing upwards (to avoid grass fires) soon ...
Turboshaft engine with a maximum and normal power rating of 2,200 and 1,850 shp (1,640 and 1,380 kW) and a pressure ratio of 6:1; high-speed version of the T55-L-3 [21] allowed for use on the Chinook instead of the geared YT55-L-3 engine due to August 1958 engine contract modification, with the reduction gearing now provided in the helicopter ...
The General Electric T64 is a free-turbine turboshaft engine that was originally developed for use on helicopters, but which was later used on fixed-wing aircraft as well. General Electric introduced the engine in 1964. The original engine design included technical innovations such as corrosion resistant and high-temperature coatings. [1]
The Bell 412 is a utility helicopter of the Huey family manufactured by Bell Helicopter. It is a development of the Bell 212 , with the major difference being the composite four-blade main rotor. It is a twin-turbine helicopter that has been popular on the civilian and military markets, and major users include Canada, Italy, and Japan.
The first gas turbine engine considered for an armoured fighting vehicle, the GT 101 which was based on the BMW 003 turbojet, was tested in a Panther tank in mid-1944. [4] [page needed] The first turboshaft engine for rotorcraft was built by the French engine firm Turbomeca, led by its founder Joseph Szydlowski. In 1948, they built the first ...
The Boeing T50 (company designation Model 502) was a small turboshaft engine produced by Boeing. It was the first turboshaft engine to ever power a helicopter: a modified Kaman K-225 in 1951. [1] Based on Boeing's earlier Model 500 gas generator, the T50's main application was in the QH-50 DASH helicopter drone of the 1950s.
