M250 Turboshaft: Helicopter Engine - Rolls-Royce
Two-shaft modular design featuring a two-stage LP turbine, two-stage HP turbine, and a gearbox with 6,000rpm output. Compressed air is routed to the aft end of the engine for combustion, with exhaust gases exiting from the middle of the engine.
How Do Helicopter Engines Work? The Pilot Explains
Helicopter engines can be either piston or gas turbine turboshaft. Air is drawn in, compressed, mixed with fuel, ignited, then the rapid expansion of the gas is harnessed to turn a drive shaft which is fed to the main transmission. The engines use …
The Helicopter Turbine Engine: A primer on these rotorcraft engines
2004年2月29日 · The following is a brief excerpt from the book "Cyclic and Collective" by Shawn Coyle. It is taken from the chapter discussing turbine engines on helicopters. Turbine engines are...
Honeywell T55 - Wikipedia
The Honeywell T55 (formerly Lycoming; company designation LTC-4) is a turboshaft engine used on American helicopters and fixed-wing aircraft (in turboprop form) since the 1950s, and in unlimited hydroplanes since the 1980s. As of 2021, more …
RR300 | Rolls-Royce
Designed as a replacement for piston engines in light helicopters and general aviation aircraft, the engine is optimised for performance in the 240-300 shp power range. The engine has a certified multi-fuel capability and proven turbine engine responsiveness, smoothness and …
Development of the gas turbines and turboshafts especially really picked up in the 1950s era. One of the first was the Turbomeca Artouste which was originally designed as an APU later becoming the Turmo engine. However, the first engine to power a helicopter was the Boeing T50 turboshaft, which flew on the Karam K225 Synchropter in 1951.
Solar T62 - Wikipedia
The Solar T62 Titan is an American gas turbine engine used mainly as a aircraft auxiliary power unit (APU), conventional power generator, turboprop engine for fixed-wing aircraft or turboshaft engine for helicopters. A new turbine version was developed as the Solar T66.
General Electric GE38 - Wikipedia
The General Electric GE38 is a gas turbine developed by GE Aviation for turboprop and turboshaft applications. It powers the Sikorsky CH-53K King Stallion as the T408. [1]
Ideal cycle analyses of the Boeing 502-14 and of the General Electric T64 turboshaft engine are performed. Turboshafts are an adaptation of gas turbine technology in which the principle output is shaft power from the expansion of hot gas through the turbine, rather than thrust from the exhaust of these gases.
New Hill GT50 Turbine Engine - HILL HELICOPTERS
The GT50 is a two-spool turboshaft engine, comprising a single stage centrifugal compressor with a pressure ratio of 7.0:1 at 46,000rpm, driven by a single-stage axial turbine, specifically optimised for high efficiency, low fuel consumption and long-life.
