Jet engines can be dated back to the invention of the aeolipile around 150 BC. This device used steam power directed through two nozzles so as to cause a sphere to spin rapidly on its axis. [ 1] So far as is known, it was not used for supplying mechanical power, and the potential practical applications of this invention were not recognized.
Air Commodore Sir Frank Whittle, OM, KBE, CB, FRS, FRAeS [1] (1 June 1907 – 8 August 1996) was an English engineer, inventor and Royal Air Force (RAF) air officer. He is credited with having invented the turbojet engine. A patent was submitted by Maxime Guillaume in 1921 for a similar invention which was technically unfeasible at the time.
A jet engine is a type of reaction engine, discharging a fast-moving jet of heated gas (usually air) that generates thrust by jet propulsion. While this broad definition may include rocket, water jet, and hybrid propulsion, the term jet engine typically refers to an internal combustion air-breathing jet engine such as a turbojet, turbofan ...
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. The jet engine was clearly an idea whose time had come. Frank Whittle submitted his first patent in 1930. By the late 1930s ...
Associated with the California Institute of Technology (Caltech), Parsons was one of the principal founders of both the Jet Propulsion Laboratory (JPL) and the Aerojet Engineering Corporation. He invented the first rocket engine to use a castable, composite rocket propellant, [1] and pioneered the advancement of both liquid-fuel and solid-fuel ...
He invented a great number of devices, designed a "flying saucer" and discovered the Coandă effect of fluid dynamics. In the 1950s, Coandă inflated his importance in aviation history, describing falsely how he had invented the air-breathing jet engine and incorporated that design into the Coandă-1910 aircraft. However, his ducted engine ...
Hans von Ohain. Hans Joachim Pabst von Ohain (14 December 1911 – 13 March 1998) was a German physicist, engineer, and the designer of the first turbojet engine to power an aircraft. [ 1] Together with Frank Whittle he has been described as the co-inventor of the turbojet engine. However, the historical timelines show that von Ohain was still ...
Jet aircraft. A jet aircraft (or simply jet) is an aircraft (nearly always a fixed-wing aircraft) propelled by one or more jet engines . Whereas the engines in propeller-powered aircraft generally achieve their maximum efficiency at much lower speeds and altitudes, jet engines achieve maximum efficiency at speeds close to or even well above the ...
