The air that goes around the engine has a slight more velocity than the free stream.
Like the turbojet, it uses the same gas generator core i.e compressor, combustor, turbine, to produce thrust & turbine is used to run the compressor as well as the fan.
A turbofan engine is a engine very similar to the jet engine.Turbofan engines – Animation showing the air bypassing the engine & its working ! The discharged gases are then allowed to exit through nozzle at high speed which produces thrust & propels the aircraft.įor detailed explanation of a jet engine’s parts, their functions & its working, read one of my previous articles – How do jet engines work ?.The turning of turbine also helps to run the compressor as they are connected to the same drive shaft. These hot expanding gases are then made to flow through turbine which causes the blade to rotate.Combustion takes place into the chamber & high amount of exhaust gases are produced. As the air is already at high pressure and high temperature, fuel is injected into it.The compressed air is then forced into the combustion chamber. The fans in the front does the work of compressor.Also you could see that air is flowing faster while leaving the nozzle than while entering. Types of jet engines/gas turbines :- Turbojet engines – Animation of working of a jet engine. Unlike the internal combustion engines in automobiles & trucks which convert the up & down movement of the piston to rotary movement of crankshaft, jet engines simply produces power by sucking air at the front side & discharging it at the back side. Jet engines are internal combustion engines discharging hot exhaust gases at high velocity that generate thrust. Todays jet engines are able to produce so much of thrust that airplanes could fly at speeds multiple times the speed of sound ! Jet engines :. There are many types of jet engines depending on their construction & power they can deliver. Its been more than 75 years, there has been continuous development in jet engines & has a significant increase in their efficiency. Whittle, who registered a patent for the turbojet engine in 1930, received that recognition but did not perform a flight test until 1941. Hans von Ohain of Germany was the designer of the first operational jet engine, though credit for the invention of the jet engine went to Great Britain’s Frank Whittle. The first jet engine successfully flew in August, 1939.
