Turboprop Engines

Turbo Propeller Engines are one of the widely used Jet Engines for short haul flights.

What is TurboProp Engines and how do they work:

A turboprop Engine is a jet engine attached to a propeller.

The turbine at the back is turned by the hot gases, and this turns a shaft that drives the propeller.

Some small airliners and transport aircraft are powered by turboprops.


Like the turbojet, the turboprop engine consists of a compressor, combustion chamber, and turbine, the air and gas pressure is used to run the turbine, which then creates power to drive the compressor.

Compared with a turbojet engine, the turboprop has better propulsion efficiency at flight speeds below about 500 miles per hour.

Modern turboprop engines are equipped with propellers that have a smaller diameter but a larger number of blades for efficient operation at much higher flight speeds.

To accommodate the higher flight speeds, the blades are scimitar-shaped with swept-back leading edges at the blade tips.


Engines featuring such propellers are called PropFans.
