Jet engine

How does a jet engine work?


Aviation owes a lot to the jet engine. This revolutionary invention made it possible to exceed the speed of the fastest propeller plane, or 700 km/h. Modern commercial aircraft fly with a jet engine at speeds of 850 km/h and more.

Jet engines even made it possible to fly faster than the speed of sound. Here we explain exactly how a jet engine works.

The start of a new propulsion principle

As early as the beginning of the 20th century, a number of scientists and engineers began playing around with the idea of using the recoil principle. The plan was to utilise this principle to generate thrust for propulsion. Success came in the second half of the 1930s. Frank Whittle in England and Hans von Ohain in Germany each developed a new drive of this type independently. This led to the first plane that used a jet engine instead of a propeller drive.
