How does the jet engine work?

Gas turbine, or jet engine, was the first alternative to the propeller as a means to ensure that the aircraft move in the sky. Like most engines, the internal combustion engine that produces a pull in a classic four -stroke cycle: induction , compression , ignition and exhaust . Unlike the propeller planes, which convert an overheated exhaust with internal combustion to mechanical power to control the rotor, the current of the jet engine comes directly from the exhaust gas, fired from the rear of the engine in the shape of the tube. While the maximum propeller speed is 0.8 around Mach, different jetplans can reach Mach 15 or higher (see scramjet ), although Mach 1.0 to 2.0 is more typical.

The world's first motor level, He 178, was designed at the end of the 30th year by German engineer Hans von Ohain and a summer from Marienehe Aerodrome test pilot Erich Warsitz on August 27, 1939.Ane in 1941. Proposals for the birth of Americans were not implemented until the 1960s. The creation of Jetplane was a milestone in aviation that was not seen from the historic flight of the Wright Brothers brothers in Kitty Hawk.

Jet Engine was originally developed to overcome the declining yields of propelle -based designs when the radial speed of the propeller began to approach the speed of sound. Unlike a slightly acceleration of large air mass, as in the propeller, the jet engine works on the principle of accelerating less air weight to a very high speed. Instead of being mounted in front of the aircraft as a propeller, the jet engine is mounted on the wings or at the rear.

The nozzle cycle begins when the rapidly moving air is sucked into the chamber on the front of the engine and then compressed by a series of blades that move at gradually higher RPM. Port of adding, Becausje it gets angry air directlyFrom the flight path of the aircraft, it is covered with a wire mesh or grid to prevent foreign objects from entering. When moving air reaches a high level of compression, it is combined with fuel and ignited, the exhaust port is fired at the rear of the current engine. Due to the huge amount of heat generated, sophisticated cooling systems are required to prevent the melting of the engine.

There are many different variants on the design of the jet engine that mix different structures and techniques and create jetplany suitable for different speeds and altitudes. These variants include Turbojet, Turbofan, Ramjet, Scramjet, Pulsejet and several others.
