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.
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 ...
In the 1930s, development of the jet engines began in Germany and in Britain and they began testing in 1939 before World War II. The jet engine saw considerable development during the war, with a few jet powered aircraft being used in the war. [139] First female combat pilot, Sabiha Gökçen, reviews her Breguet 19

The General Electric I-A was the first working jet engine in the United States, manufactured by General Electric (GE) and achieving its first run on April 18, 1942.. The engine was the result of receiving an imported Power Jets W.1X that was flown to the US from Britain in 1941, and the I-A itself was based on the design of the improved Power Jets W.2B, the plans of which were also received.
(Earliest GE jet engines, based on the Whittle design and developed with Allison, featured a centrifugal compressor. GE and Allison had the Army contract to develop a ‘land based’ jet while the Westinghouse Navy contract was for carrier-based Navy jet fighters. ) One year later, an improved Model 19B, the 19XB-2B, changed to a 10 stage ...
In Rugby where Whittle produced his first prototype engines, a bronze sculpture named Frank Whittle – Father of the Jet Engine was installed at Chestnut Field near Rugby Town Hall in 2005. It was made by the sculptor Stephen Broadbent, and represents a propeller transformed into an internal turbine of a jet engine. [114] [115]
