A combustor is a component or area of a gas turbine, ramjet, or scramjet engine where combustion takes place. It is also known as a burner, burner can, combustion chamber or flame holder. In a gas turbine engine, the combustor or combustion chamber is fed high-pressure air by the compression system. The combustor then heats this air at constant ...
The combustion chamber in gas turbines and jet engines (including ramjets and scramjets) is called the combustor. The combustor is fed with high pressure air by the compression system, adds fuel and burns the mix and feeds the hot, high pressure exhaust into the turbine components of the engine or out the exhaust nozzle.
A free-piston gas generator is a free-piston engine whose exhaust is used to power a gas turbine. It combines the functions of compressor and combustion chamber in one unit. These machines were quite widely used in the period 1930–1960 but then fell out of favour. [1]
The propelling nozzle converts a gas turbine or gas generator into a jet engine. Power available in the gas turbine exhaust is converted into a high speed propelling jet by the nozzle. The power is defined by typical gauge pressure and temperature values for a turbojet of 20 psi (140 kPa) and 1,000 °F (538 °C). [18]
The Westinghouse Aviation Gas Turbine Division (AGT) was established by Westinghouse Electric Corporation in 1945 to continue the development and production of its gas turbine engines for aircraft propulsion under contract to the US Navy Bureau of Aeronautics. The AGT Division was headquartered in Kansas City, Missouri, where it remained in ...
The Packard XJ41 met those requirements with a combination of a mixed flow compressor, a lightweight annular combustion chamber and hollow turbine blades for both rotor and stator. The engine's most outstanding design characteristic was the use of an air inlet that operated at supersonic speed that produced more thrust per pound of weight than ...
Initially, the first engines developed (GT-300 and 302) did not have a regenerator, but adding regeneration to recapture heat from the exhaust gases was found to reduce fuel consumption by 1 ⁄ 2 for the second-generation GT-304, so subsequent generations of GM Whirlfire gas turbine engines incorporated a regenerator.
