Axial Compressors

Fluid flow is parallel to axis of rotation

Used in modern aircraft

Have several stages to increase compression pressure ratio

Used in modern gas turbine engines

 

Advantages	Disadvantages
High peak efficiency.	High weight
Small frontal area forgiven airflow	High manufacturing costs
Multistage allows for increase in CPR	High starting power requirements

Centrifugal Compressor

Fluid flow is perpendicular to the axis of rotation

Used in first jet turbine engines

Advantages	Disadvantages
Larger CPR per stage	Cannot be used in stages
Simple and rugged
Shorter in length
