J47
The General Electric J47 turbojet (GE company designation TG-190) was developed by General Electric from its earlier J35. 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. Design and development The J47 design used experience from the TG-180/J35 engine which was described by ''Flight'' magazine in 1948 as the most widely used American-conceived turbojet. Overhaul life for the J47 ranged from 15 hours (in 1948) to a theoretical 1,200 hours (625 achievable in practice) in 1956. For example, the J47-GE-23 was rated to run 225 hours time between overhauls. As installed on the F-86F, it experienced one in-flight shutdown every 33,000 hours in 1955 and 1956.

Boeing B-47 Stratojet
The Boeing B-47 Stratojet (Boeing company designation Model 450) is a retired American long-range, six-engined, turbojet-powered strategic bomber designed to fly at high subsonic speed and at high altitude to avoid enemy interceptor aircraft. The primary mission of the B-47 was as a nuclear bomber capable of striking targets within the Soviet Union. Development of the B-47 can be traced back to a requirement expressed by the United States Army Air Forces (USAAF) in 1943 for a reconnaissance bomber that harnessed newly developed jet propulsion. Another key innovation adopted during the development process was the swept wing, drawing upon captured German research. With its engines carried in nacelles underneath the wing, the B-47 represented a major innovation in post-World War II combat jet design, and contributed to the development of modern jet airliners. Suitably impressed, in April 1946, the USAAF ordered two prototypes, designated "XB-47"; on 17 December 1947, the first ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North American F-86E Sabre
The North American F-86 Sabre, sometimes called the Sabrejet, is a transonic jet fighter aircraft. Produced by North American Aviation, the Sabre is best known as the United States' first swept-wing fighter that could counter the swept-wing Soviet MiG-15 in high-speed dogfights in the skies of the Korean War (1950–1953), fighting some of the earliest jet-to-jet battles in history. Considered one of the best and most important fighter aircraft in that war, the F-86 is also rated highly in comparison with fighters of other eras. Although it was developed in the late 1940s and was outdated by the end of the 1950s, the Sabre proved versatile and adaptable and continued as a front-line fighter in numerous air forces. Its success led to an extended production run of more than 7,800 aircraft between 1949 and 1956, in the United States, Japan, and Italy. In addition, 738 carrier-modified versions were purchased by the US Navy as FJ-2s and -3s. Variants were built in Canada and Aus ...

North American FJ-2 Fury
The North American FJ-2 and FJ-3 Fury are a series of swept-wing carrier-capable fighters for the United States Navy and Marine Corps. The FJ-2 resulted from an effort to navalize the North American F-86 Sabre operated by the United States Air Force. These aircraft feature folding wings, and a longer nose landing strut designed to increase angle of attack upon launch and to accommodate a longer oleo to absorb the shock of hard landings on an aircraft carrier deck. Although sharing a U.S. Navy designation with its distant predecessor, the straight-winged North American FJ-1 Fury, the FJ-2/-3 were completely different aircraft. (The later FJ-4 was again, a complete structural redesign of the FJ-3). The FJ-2 was one of the aircraft used to evaluate the first steam catapult on a US Navy aircraft-carrier. Design and development FJ-2 By 1951, the Navy's existing straight-wing fighters were inferior in performance to the swept-wing Soviet Mikoyan-Gurevich MiG-15 then operating in ...

General Electric J73
The General Electric J73 turbojet was developed by General Electric from the earlier J47 engine. Its original USAF designation was J47-21, but with innovative features including variable inlet guide vanes, double-shell (inner and outer) combustor case, and 50% greater airflow was redesignated J73. Its only operational use was in the North American F-86H. Design and development An engine, uprated from the J47, was required for the F-86H. The mass flow was increased by relocating accessories from the centre of the compressor inlet to the underside of the engine. This allowed a reduction in blade hub diameter, which together with an increase in tip diameter, gave a bigger area for air to enter the compressor. The area through the combustion chambers also had to be increased. This was done by replacing the multiple individual chambers with a single annular casing with individual flame tubes or cans known as cannular. The pressure ratio was increased and variable inlet guide vanes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Allison J35
The General Electric/Allison J35 was the United States Air Force's first axial-flow (straight-through airflow) compressor jet engine. Originally developed by General Electric (GE company designation TG-180) in parallel with the Whittle-based centrifugal-flow J33, the J35 was a fairly simple turbojet, consisting of an eleven-stage axial-flow compressor and a single-stage turbine. With the afterburner, which most models carried, it produced a thrust of . Like the J33, the design of the J35 originated at General Electric, but major production was by the Allison Engine Company. Design and development While developing the T31 axial turboprop in 1943 General Electric realized that they had the resources to design an axial flow turbojet at the same time as their centrifugal-flow J33 engine. They recognized the axial would have more potential for the future and went ahead with the TG-180 engine. GE axial compressor designs were developed from the NACA 8-stage compressor. The e ...

North American B-45 Tornado
The North American B-45 Tornado was an early American jet bomber designed and manufactured by aircraft company North American Aviation. It has the distinction of being the first operational jet bomber to enter service with the United States Air Force (USAF), as well as the first multiengine jet bomber to be refueled in midair. The B-45 originated from a wartime initiative launched by the U.S. War Department, which sought a company to develop a jet-propelled bomber to equal those being fielded by Nazi Germany, such as the Arado Ar 234. Following a competitive review of the submissions, the War Department issued a contract to North American to develop its ''NA-130'' proposal; on 8 September 1944, work commenced on the assembly of three prototypes. Progress on the program was stalled by post-war cutbacks in defense expenditure, but regained importance due to growing tensions between America and the Soviet Union. On 2 January 1947, North American received a production contract fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boeing KC-97 Stratofreighter
The Boeing KC-97 Stratofreighter is a four-engined, piston-powered United States strategic tanker aircraft based on the Boeing C-97 Stratofreighter. It replaced the KB-29 and was succeeded by the Boeing KC-135 Stratotanker. Design and development The KC-97 Stratofreighter was an aerial refueling tanker variant of the C-97 Stratofreighter (which was itself based on the Boeing B-29 Superfortress), greatly modified with all the necessary tanks, plumbing, and a flying boom first developed for the KB-29 bomber. The cavernous upper deck was capable of accommodating oversize cargo accessed through a very large right-side door. In addition, transferable jet fuel was contained in tanks on the lower deck (G-L models). Both decks were heated and pressurized for high altitude operations. The boom operator lay prone, viewing operations through a window at the bottom of the tail, a configuration later used on the KC-135 ''Note: Occasionally the KC-97 has been referred to as "Stratotanker". ...
