the definition of
The gas turbine, also called combustion turbines, is a rotary engine that extracts energy from a flow of combustion gas.



Overview
It has an upper stream compressor, coupled with a thread on the bottom of the turbine and combustion chamber, in-between.
Energy is added to the gas flow in the combustion chamber, where the air is mixed with fuel and vosplamen. Combustion increases the temperature, speed and volume of the gas flow. This is directed through a nozzle over the blades of the turbine, the rotation of the turbine and compressor power.
Energy is extracted in the form of shaft power, compressed air and thrust, in any combination, and used to power aircraft, trains, ships, generators, and even tanks.

Principle of operation
Gas turbines are described thermodynamically by the Brayton cycle in which air is compressed izèntropičeski, combustion occurs at constant pressure, and expansion in the turbine is izèntropičeski back to the starting pressure.
In practice, friction and turbulence cause:
Izèntropičeskim-compression) numbers with a ratio of the total pressure, the compressor outlet temperature is more than perfect.
b not izèntropičeskoe extension), although the temperature of the turbine, the compressor is not in motion changes, the attitude is more pressure, resulting in a reduced extension that provides useful work.
the) pressure loss in combustion chamber-reduces the expansion available to provide useful work ....
