WebIn supersonic flight, the inlet to a turbojet engine must be designed so that the intake to the compressor occurs at subsonic speeds. This is done using a duct and/or doors or baffles in which the total pressure increases according to the thermodynamic relationship (8) WebA turbojet engine is used in Aircraft. These are air-breathing engines which suck in air from the atmosphere for combustion. It has various components like inlet, compressor, …
WebA ramjet is a straightforward air-breathing jet engine with no rotating or moving parts, much like an afterburner. Ramjets employ a continuous combustion process where fuel is … WebIn a turbojet all the air entering the intake passes through the gas generator, which is composed of the compressor, combustion chamber, and turbine. In a turbofan engine, by contrast, only a portion of the incoming air does so. The remainder passes through a fan, or low-pressure compressor, and is ejected directly as a "cold" jet or mixed with ...
WebAs with all engines there are four “stages” in the combustion cycle for both turbojets and turbofans: intake, compression, combustion and exhaust. These stages occur simultaneously and continuously through the engine … Webcombustor (burner).

The turbojet is an airbreathing jet engine which is typically used in aircraft. It consists of a gas turbine with a propelling nozzle. The gas turbine has an air inlet which includes inlet guide vanes, a compressor, a combustion chamber, and a turbine (that drives the compressor). The compressed air from the … See more The first patent for using a gas turbine to power an aircraft was filed in 1921 by Frenchman Maxime Guillaume. His engine was to be an axial-flow turbojet, but was never constructed, as it would have required … See more Air intake An intake, or tube, is needed in front of the compressor to help direct the incoming air smoothly into the rotating compressor blades. Older engines had stationary vanes in front of the moving blades. These vanes also helped to … See more The operation of a turbojet is modelled approximately by the Brayton cycle.
