What are the two types of GTE compressors?

The two primary types of gas turbine engine (GTE) compressors are axial and centrifugal. Axial compressors operate by using a series of rotating blades (rotors) followed by stationary blades (stators) oriented in a direction parallel to the axis of the compressor. This design allows for a continuous flow of air along the axis, making axial compressors efficient for high throughput and pressure ratios, which is essential in most gas turbine applications.

Centrifugal compressors, on the other hand, work by converting kinetic energy from the rotating impeller into pressure energy. As air moves through the impeller, it is flung outward by centrifugal force, thereby increasing its pressure. This type of compressor is typically used in smaller gas turbines and is known for its robustness and compact design.

Understanding these two types' operating principles and applications is crucial for gas turbine systems technicians as it directly influences engine design, performance characteristics, and operational efficiencies within gas turbine systems.
