turbine engine
- Definição1
- A form of internal combustion engine that consists principally of a turbine-driven air compressor and a combustion chamber. Fuel is sprayed into the compressed air and ignited inside the combustion chamber. Heat from the burning fuel expands the air which is forced through the turbine to spin it and drive the compressor.

- Nota Adicional1
- The turbine engine has the following advantages over a reciprocating engine: less vibration, increased aircraft performance, reliability, and ease of operation.
- Contexto
- Unlike a piston engine, the combustion in a turbine engine is continuous. An igniter plug serves only to ignite the fuel/air mixture when starting the engine. Once the fuel/air mixture is ignited, it will continue to burn as long as the fuel/air mixture continues to be present. If there is an interruption of fuel, air, or both, combustion ceases. This is known as a "flame-out," and the engine has to be restarted or re-lit. Some helicopters are equipped with auto-relight, which automatically activates the igniters to start combustion if the engine flames out.
