This article outlines the important developments in the history of the development of the air-breathing (duct) jet engine.Although the most common type, the gas turbine powered jet engine, was certainly a 20th-century invention, many of the needed advances in theory and technology leading to this invention were made well before this time.
Gas turbine engines, commonly called "jet" engines, could do that. The key to a practical jet engine was the gas turbine, used to extract energy from the engine itself to drive the compressor. The gas turbine was not an idea developed in the 1930s: the patent for a stationary turbine was granted to John Barber in England in 1791.
The history of aviation spans over two millennia, from the earliest innovations like kites and attempts at tower jumping to supersonic and hypersonic flight in powered, heavier-than-air jet aircraft. Kite flying in China, dating back several hundred years BC, is considered the earliest example of man-made flight. [ 1 ]
For commercial jet aircraft the jet noise has reduced from the turbojet through bypass engines to turbofans as a result of a progressive reduction in propelling jet velocities. For example, the JT8D, a bypass engine, has a jet velocity of 400 m/s (1,450 ft/s) whereas the JT9D, a turbofan, has jet velocities of 300 m/s (885 ft/s) (cold) and 400 ...
The ramjet engine was designed by French engineer René Leduc. 1957: The first working prototype of the pistonless Wankel engine (sometimes called a rotary engine) is built by German engineer Felix Wankel. 1957: First usage of electronic fuel injection (EFI) in a production passenger car, using the American Bendix Electrojector system.

Although production and support of the J34 continued, Westinghouse exited the jet engine business in 1960, closing the Kansas City operation, after having supplied engines for 1223 Navy jet planes. Ironically, the first Pan Am Boeing 707 had just flown its maiden commercial flight, powered by Pratt & Whitney jet engines, just a year earlier. A ...
An aircraft engine, often referred to as an aero engine, is the power component of an aircraft propulsion system. Aircraft using power components are referred to as powered flight . [ 1 ] Most aircraft engines are either piston engines or gas turbines , although a few have been rocket powered and in recent years many small UAVs have used ...
