Compressor Section Of A Gas Turbine Engine

The turbine section of the gas turbine engine has the task of producing usable output shaft power to drive the propeller.

Compressor section of a gas turbine engine. Idealized simple open cycle gas turbine engine most gas turbines operate on an open cycle in which air is taken from the atmosphere compressed in a centrifugal or axial flow compressor and then fed into a combustion chamber. Specifically it is directly behind the combustion chamber outlet. Diagram of a typical gas turbine jet engine.

29 8136 the basic gas turbine engine is divided into two main sections. Here fuel is added and burned at an essentially constant pressure with a portion of the air. The compressor section of the gas turbine engine has many functions.

Gas turbine engine gas turbine engine major components of gas turbine engines. Specifically to fulfill its purpose the compressor must increase the pressure of the mass of air received from the air inlet duct and then discharge it to the burners in the quantity and at the pressures required. The hot exhaust gases provide forward thrust and turn the turbines which drive the compressor fan blades.

Axial compressor centrifugal compressor and mixed flow compressor. Early gas turbines employed centrifugal compressors which are relatively simple and inexpensive. Its primary function is to supply air in sufficient quantity to satisfy the requirements of the combustion burners.

They are however limited to low pressure ratios and cannot match the efficiencies of modern axial flow compressors. The items discussed for axial compressors apply to the compressor section of the gas turbine and need not be repeated. The compressor section of the engine has the important task of providing a sufficient quantity of compressed air to satisfy the requirements of combustion.

These turbine stages can be used to drive a low pressure compressor fan propeller and shaft. The gas turbine is a complex machine and because of this would tend to be unreliable. In addition it must also provide power to drive the compressor and all engine accessories.
