64.8 Turbine Engine Compressors
64.8.2 Describe the purpose of a compressor in a turbine engine.
A compressor in a turbine engine is used to increase the pressure of the incoming air before it enters the combustion chamber, resulting in more efficient combustion.
The compressor in a turbine engine compresses incoming air to increase its pressure and density before it enters the combustion chamber.
This allows for more fuel to be burned, which generates more energy to power the engine.
64.8.4 Describe the basic principles of operation of centrifugal and axial flow compressors.
A centrifugal compressor works by accelerating the incoming air radially outward, which increases the air's velocity and then converts the velocity into pressure.
An axial flow compressor works by accelerating the incoming air parallel to the axis of rotation, which increases the air's velocity and then converts the velocity into pressure.
64.8.6 Describe the compressor arrangements found on the various types of turbine engine.
There are three main types of compressor arrangements found on turbine engines:
- single-stage centrifugal,
- multi-stage centrifugal, and
- axial flow.
