How engines work?
Jet engines move the airplane forward with a great force that is produced by a tremendous thrust and causes the plane to fly very fast. All jet engines, which are also called gas turbines, work on the same principle. The engine sucks air in at the front with a fan. A compressor raises the pressure of the air. The compressor is made with many blades attached to a shaft. The blades spin at high speed and compress or squeeze the air. The compressed air is then sprayed with fuel and an electric spark lights the mixture. The burning gases expand and blast out through the nozzle, at the back of the engine. As the jets of gas shoot backward, the engine and the aircraft are thrust forward. As the hot air is going to the nozzle, it passes through another group of blades called the turbine. The turbine is attached to the same shaft as the compressor. Spinning the turbine causes the compressor to spin. Follow us on facebook :

Homemade electric jet engine actually works!
This is a model of a jet engine (scale 1:90) that was made with an electric motor that moves a set of gears, with a flywheel that spins in 16:1 ratio, taken from a flywheel-driven toy car. The best part is that the flywheel makes the model react and sound similar to a real full-size jet engine! Source & embed code: ale.html. For licensing, please email
