JET ENGINES.

Necessitated the fight in World War II for faster aircraft and the Rolls-Royce engine, which was supplied to the Spitfire fighter jets, had exhausted the possibilities of development and improvement.

So the British government developed the jet engine invented by Frank Wittel in 1939.As soon as the end of the Second World War ended, the governments of the Axis countries and the Allies themselves had a number of Jet fighters. Since ever, jet engines have become the main source of power for most large aircraft. The Jetplane pushing force is derived from the rushing gas in a high speed produced by the burned fuel in the combustion tube directed by the jet engines.

If you tried to blow a rubber balloon in the air and then fired it, you notice that the balloon is moving in the opposite direction to the air from it. The release of the air you pump into the balloon generates an equal and counter-reaction in the direction, In the jet engine, high-pressure gases are generated by the combustion of kerosene fuel in a series of burning combustion chambers that surround the engine and draw air to burn it from the front of the engine. The gases released from combustion chambers are used to run a turbocharged turbine prior to its release from the nozzle in the rear of the engine.

The axis of the turbine is connected to a rotary device at the front of the engine that presses the air into the combustion chambers, thus burning more fuel and generating larger amounts of gas.

In the turbocharged jet engine, some drawn air is mixed from the front of the engine with the hot gases emitted at the rear of the engine. The single-jet aircraft are adopted by the engine, often military aircraft around the same engine. The larger aircraft have two, three, four or more engines suspended in under-wing conditions or connected to the back of the body or part of the tail.Indeed, supersonic flight was not possible without the jet engines. The Concorde, for example, is equipped with upgraded jet engines that enable it to start at speeds of slightly more than twice the speed of sound.

Jet Engine theory.

The simplest type of jet engine is the covered jet. It does not contain moving parts. It consists mainly of a long tube, which is why it is sometimes referred to as the flying bank. It works in the middle of the pipe as a combustion chamber and ends as a puffing hole. In the course of the start of the pipe motor through the air, the air is pushed into the combustion chamber where the fuel is injected.By burning the injected fuel into the moving air, hot gases are generated that escape from the jetting nozzle faster than the inside air. This produces a force that makes the jet tube fly through the air. The covered jet engine only works when it is a springboard.
