It is air that makes the operation of a gas turbine aircraft engine possible. The air flow compressed in the compressor is mixed with fuel in the combustion chamber. The resulting hot gas accelerates to enormous speed in the turbine and causes it to rotate, the United Engine Corporation (UEC) reported.
The turbine rotates the compressor, drives the engine, and the hot gas at the outlet creates thrust in the nozzle, which propels the aircraft. In order for all this to happen, the air must first be compressed.
The most visible part of a gas turbine aircraft engine is a large fan. It has complex-shaped blades installed – as they rotate, they draw air into the engine. Most of it goes into the outer circuit, and a smaller, but most significant part goes into the inner circuit of the engine.
In the inner circuit, air enters the compressors – first into the low-pressure compressor, then into the high-pressure compressor. It is the compressors that compress the air before it is fed into the combustion chamber.
As it passes through the compressors, the air is highly compressed – its density increases by 10-45 times – and heats up. The air pressure in the compressor before entering the combustion chamber can reach 50 atmospheres. Aircraft engine compressors create such high pressure using a complex system of blades.
