TURBINE ENGINES






A gas turbine, or a combustion turbine, is a rotary engine that produce energy from a flow of combustion gas.

It has a compressor coupled to a downstream turbine, and a combustion chamber in-between. 
Gas turbine  also called just the turbine component. 
Air is sucked in by the intake portion of the engine and added to compressor which compress this air to a high potential.
The compressed air is subjected to combustion chamber where it is mixed with fuel spray and ignition source. The high potential burning mixture flow is directed througha nozzleover the turbine's blades, spinning the turbine which powers the compressor (turbine & compressor are coupled togather by a shaft) and, for some turbines, drives their mechanical output. when the hot gases exhuasts, it produce a thrust for the engine which pushes the A/C in forward direction.


The following diagram shows how air enters, compresses and after combustion produce thrust from the exhaust gases.
