Since the thrust that could be developed by the piston engine is limited‚ they cannot be used in aircrafts that need high speed and thrust. Hence‚ piston engines are mostly restricted to training flights and slow flights. There were many modifications like the supercharger that were added to the piston engine which provided extras thrust to the existing engines. The supercharger

    The Evolution of Jet Engines The jet engine is a complex propulsion device which draws in air by means of an intake‚ compresses it‚ heats it by means of an internal combustion engine‚ which when expelled it turns a turbine to produce thrust‚ resulting in a force sufficient enough to propell the aircraft in the opposite direction (Morgan 67). When the jet engine was thought of back in the 1920’s the world never thought it would become a reality‚ but by 1941 the first successful jet flight was
