gas-turbine engine — Introduction any internal combustion engine employing a gas as the working fluid used to turn a turbine. The term also is conventionally used to describe a complete internal combustion engine consisting of at least a compressor, a… … Universalium
Gas compressor — A gas compressor is a mechanical device that increases the pressure of a gas by reducing its volume. Compressors are similar to pumps: both increase the pressure on a fluid and both can transport the fluid through a pipe. As gases are… … Wikipedia
Gas turbine — Microturbine redirects here. For turbines in electricity, see Small wind turbine. For turbines driven by the flow of gas, see Turbine. A typical axial flow gas turbine turbojet, the J85, sectioned for display. Flow is left to right, multistage… … Wikipedia
Components of jet engines — Diagram of a typical gas turbine jet engine. Air is compressed by the fan blades as it enters the engine, and it is mixed and burned with fuel in the combustion section. The hot exhaust gases provide forward thrust and turn the turbines which… … Wikipedia
de Laval nozzle — Diagram of a de Laval nozzle, showing approximate flow velocity (v), together with the effect on temperature (t) and pressure (p) A de Laval nozzle (or convergent divergent nozzle, CD nozzle or con di nozzle) is a tube that is pinched in the… … Wikipedia
De Laval nozzle — A de Laval nozzle (or convergent divergent nozzle, CD nozzle or con di nozzle) is a tube that is pinched in the middle, making an hourglass shape. It is used as a means of accelerating the flow of a gas passing through it to a supersonic speed.… … Wikipedia
Centrifugal compressor — Centrifugal compressors, sometimes termed radial compressors, are a sub class of dynamic axisymmetric work absorbing turbomachinery.[1] Centrifugal impeller with a highly polished surface likely to improve performance … Wikipedia
Choked flow — is a compressible flow effect. The parameter that becomes choked or limited is the velocity or the mass flow rate. Choked flow is a fluid dynamic condition associated with the Venturi effect. When a flowing fluid at a given pressure and… … Wikipedia
Airbreathing jet engine — An airbreathing jet engine (or ducted jet engine) is a jet engine propelled by a jet of hot exhaust gases formed from air that is drawn into the engine via an inlet duct. All practical airbreathing jet engines are internal combustion engines that … Wikipedia
