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.
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 XJ37 was being worked on at the same time as competing Westinghouse axial-flow designs undergoing development, the 19A and 19B, were being test-run through the 1943-45 period, resulting in America's first production axial-flow turbojet engine, the Westinghouse J30, of which some 260 examples were made for the earliest American military jets ...
After a visit to England mid-1941, General Henry H. Arnold was so impressed by flight demonstrations of the Gloster E.28/39 jet aircraft he had witnessed that he arranged for the Power Jets W.1X turbojet engine to be shipped by air to the U.S, along with drawings for the more powerful W.2B/23 engine, so that the US could develop its own jet engine.
With the advent of more powerful British jet engines, a single fuselage-mounted engine was more effective, and this configuration was used by nearly all subsequent fighter aircraft. [citation needed] Lockheed was the first American aircraft company to start work on a jet-powered aircraft, beginning work on the L-133 in 1939.
August: Heinkel He 178 V1, the first jet-powered aircraft, flies for the first time, powered by the HeS 3B. September: A team from the Air Ministry visits Power Jets once again, but this time Frank Whittle demonstrates a jet engine at full power for a continuous 20-minute run. They are extremely impressed, quickly contracts are offered to ...
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 ...
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 ...
