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 majority of United States jet engines from this time through the mid-1950s are licensed versions of British designs. Whittle returns to Power Jets and starts development of the improved Power Jets W.2/500 and /700 engines, so named for their thrust in kilograms-force (kgf). Westinghouse starts work on an axial-flow engine design, the WE-19.
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 ...
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.
It had a combustor section with 20 tubes (not interconnected at first), a single stage turbine and an adjustable jet exhaust nozzle. It was configured as a booster engine, with only the accessories needed to start and control the engine. The second engine built was flown in 1944 under a Chance Vought FG-1 fighter as a boost engine on the center ...
Later sent to the US in October 1941, becoming the first jet engine to run in North America. W.1A Based on W.1, 1,450 lbf (6.45KN) air-cooled turbine disc and incorporating features intended for W.2. Used for second series of test flights of E.29/39 W4041/G beginning on 16 February 1942, and fitted with fuel barostat. Later featured modified ...
In addition to pure jet engines, turbine-driven propeller engines delivered a smoother ride and better fuel efficiency. One exception to jet-powered domination by large airliners was the contra-rotating propellers turboprop design that powered the Tu-114 (first flight 1957). This airliner was able to match or even exceed the speed, capacity and ...
The WU "First Model", also known by Whittle as the first "experimental" engine, [1] and the "1st edition", [2] was the first turbojet engine to be built and run in the world. [3] Although an experimental engine and not intended for flight it was designed to be very light by normal engineering standards. [2]
