Which Type of Rotary Compressor is used in Airplanes?

By Raj Vimal|Updated : July 18th, 2022

Combustion is an important part of an Aircraft’s engine to generate power. A high quantity of high-pressure air is required to mix up with fuel for combustion. Compressors must increase the pressure of air and provide the required air to the combustion section in In engine for ignition. Generally, Axial flow compressors are used in Airplanes.

Types of Compressors:

There are two types of compressors popular for being used in aircraft. The first one is Centrifugal flow compressors, and the second one is Axial Flow compressors. In Axial flow compressors, there are two mandatory elements that help the compressor to work well is Rotor and Stator. 

Work Function of Axial Flow Compressors

A Rotor pushes the air inlet where the Stator converts those air into a high velocity that helps the engine. The main reason to use an Axial Flow compressor is it has a high flow rate and pressure ratio. That increases the fuel efficiency and generates high thrust in the engine to power the aircraft.

Work Function of Centrifugal Flow Compressors

Centrifugal flow compressors used in modern Aircraft are considered stable but not much efficient compared to Axial Flow Compressors. It produces a high-pressure ratio of about 5:1, which is less than 6:1 produced by other compressors.


Which Type of Rotary Compressor is used in Airplanes?

Axial Flow compressors are used in modern aeroplanes to generate more thrust and increased fuel efficiency. As it is known to all that Airplane fuel is expensive, and a slight change in efficiency can save a lot of money. Usually, centrifugal flow compressors are a great option, but it lacks due to their inefficient feature of the compressors

Which Type of Compressor is used in Airplanes?

  • Airline employees use Axial flow compressors in Airplanes to get increased fuel efficiency and more thrust in comparison to Centrifugal flow compressors. Rotor and Stator are the two most important elements of these compressors.

  • The major difference between Axial flow generates high-pressure air with a 6:1 ratio and produces fuel efficiency with more thrust to the engine, while centrifugal flow compressors are considered to be stable compressors and produce 5:1 ratio air.
