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 …showed first 75 words of 623 total…

Some of the basic reasons are the speed, fuel economy, and endurance of the jet engine oveer piston-driven engines. Together with the new refinements and the currently changing jet industry, future transportation will become faster and safer for the flier.
