Turbojet engines have been used in isolated cases to power vehicles other than aircraft, typically for attempts on land speed records. Where vehicles are "turbine-powered", this is more commonly by use of a turboshaft engine, a development of the gas turbine engine where an additional turbine is used to drive a rotating output shaft.
The General Electric J79 is an axial-flow turbojet engine built for use in a variety of fighter and bomber aircraft and a supersonic cruise missile.The J79 was produced by General Electric Aircraft Engines in the United States, and under license by several other companies worldwide.
The Boeing KC-135 Stratotankers were all originally powered by turbojet engines. With the demise of many airline 707s, the United States Air Force took the opportunity to buy the surplus airframes and use the engines to re-fit the KC-135As used by the Air National Guard and reserve squadrons with the civilian JT3D (designated TF33-PW-102). Over ...
The Pratt & Whitney J58 (company designation JT11D-20) is an American jet engine that powered the Lockheed A-12, and subsequently the YF-12 and the SR-71 aircraft. It was an afterburning turbojet engine with a unique compressor bleed to the afterburner that gave increased thrust at high speeds. Because of the wide speed range of the aircraft ...
The prestigious Collier Trophy for 1952 was awarded to Leonard S. Hobbs, chief engineer of United Aircraft Corporation, for "designing and producing the P&W J57 turbojet engine". The engine was produced from 1951 to 1965 with a total of 21,170 built. Many J57 models shipped since 1954 contained 7-15% of titanium, by dry weight.
The Pratt & Whitney JT9D engine was the first high bypass ratio jet engine to power a wide-body airliner. [2] Its initial application was the Boeing 747-100 , the original "Jumbo Jet". It was Pratt & Whitney 's first high-bypass-ratio turbofan.
The General Electric J85 is a small single-shaft turbojet engine. Military versions produce up to 3,500 lb f (16 kN) of thrust dry; afterburning variants can reach up to 5,000 lb f (22 kN). The engine, depending upon additional equipment and specific model, weighs from 300 to 500 pounds (140 to 230 kg).
It first flew in May 1948. The J47 was the first axial-flow turbojet approved for commercial use in the United States. It was used in many types of aircraft, and more than 30,000 were manufactured before production ceased in 1956. It saw continued service in the US military until 1978. Packard built 3,025 of the engines under license.
