The jet engine is a piece of flying technology that revolutionized the aviation industry. It was designed to overcome the shortcoming of propeller engines. The worlds' first jet engine was German designed and it came out during the late 1930's. It was in 1941, that the British tested their very first jet engine. The Americans took another two decades to come out with their own version in the 1960's.
Before getting into the mechanics of how a jet engine works, it is to be understood that it is basically an internal combustions engine that has a four-stroke cycle for producing thrust. A jet engine is constructed with four parts. They are compression, combustion, intake and the exhaust. The intake happens through an intake nacelle at the front of the jet engine. When the air blows off into the nacelle, it is compressed when it strikes the compressor's blades. This process turn on the action of the blades, which intake more and more air and compresses the air that flows inside.
The highly compressed air inside further passes to the next chamber. The chamber carries the fuel injected and burnt into it. This stage of compressed air passing through the chamber functions like catalyst which provides oxygen to the burning fuel. The pressurized air mixes with the fuel and burns into the combustion part. This happens in the assembly center. The exhaust part of the jet engine expels the air out.
This is just a basic idea of how jet engines work. There are different designs for the basic jet engine, such as different structures and techniques that are included to make it handle higher speeds and also serve efficiently when flying at higher altitudes. Different types of jet engines are pulsejet, turbojet, ramjet and there are many more. The jet engine that is used in military and civilian aircrafts is the turbo-jet engine.
