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.
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.
Jet engines have propelled high speed cars, particularly drag racers, with the all-time record held by a rocket car. A turbofan powered car, ThrustSSC, currently holds the land speed record. Jet engine designs are frequently modified for non-aircraft applications, as industrial gas turbines or marine powerplants. These are used in electrical ...
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.
With the W.1 aircraft manoeuvring would subsequently be limited (by compressor-casing stress) to 2g. Maximum jetpipe temperature was 597 °C. As development of the new design dragged on, it was decided to build a test unit "early engine" using any components that were deemed unairworthy along with test items.
The resulting Heinkel-Strahltriebwerk 1 (HeS 1), German for Heinkel Jet Engine 1, was built by hand-picking some of the best machinists in the company, much to the chagrin of the shop-floor supervisors. Hahn, meanwhile, worked on the combustion problem, an area he had some experience in. The engine was extremely simple, made largely of sheet metal.
China's much-anticipated J-35A stealth aircraft, centrepiece of this week's Zhuhai air show, has been more than a decade in the making, but experts say little is known about its capabilities. The ...
(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 ...
