How aeroplanes work?

Aeroplanes are usually pushed through the air either by propellers or by jet engines. A propeller looks like two thin, pointed wings joined end to end. As it spins around, it forces air backward. This pushes the aeroplane forward.

The engine of a propeller plane uses the power of burning fuel to turn the propeller. But a jet engine uses burning fuel to make the wheels of a turbine spin. The gases and air from the spinning turbines shoot out from the back of the engine and push the plane forward. An aeroplane with a jet engine can fly much faster than a propeller aeroplane.

Large passenger aeroplanes are usually powered by jet engines. Some jumbo jets can carry more than 400 people. They fly at a speed of 800 to 970 kilometres an hour.
