Axial-flow compressors have the following advantages:

-High peak efficiency.

-Small frontal area forgiven airflow.

-Straight-through flow, allowing high ram efficiency.

-Increased pressure rise due to increased number of stages with negligible losses.

They have the following disadvantages:

- Good efficiency over narrow rotational speed range.

-Difficulty of manufacture and high cost.

-Relatively high weight.

-High starting power requirements (this has been partially overcome by split compressors).
