Thunderjet
The Republic F-84 Thunderjet was an American turbojet fighter-bomber aircraft. Originating as a 1944 United States Army Air Forces (USAAF) proposal for a "day fighter", the F-84 first flew in 1946. Although it entered service in 1947, the Thunderjet was plagued by so many structural and engine problems that a 1948 U.S. Air Force review declared it unable to execute any aspect of its intended mission and considered canceling the program. The aircraft was not considered fully operational until the 1949 F-84D model and the design matured only with the definitive F-84G introduced in 1951. In 1954, the straight-wing Thunderjet was joined by the swept-wing F-84F Thunderstreak fighter and RF-84F Thunderflash photo reconnaissance aircraft. The Thunderjet became the USAF's primary strike aircraft during the Korean War, flying 86,408 sorties and destroying 60% of all ground targets in the war as well as eight Soviet-built MiG fighters. Over half of the 7,524 F-84s produced served with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Republic F-84F Thunderstreak
The Republic F-84F Thunderstreak was an American swept-wing turbojet fighter-bomber. While an evolutionary development of the straight-wing F-84 Thunderjet, the F-84F was a new design. The RF-84F Thunderflash was a photo reconnaissance version. Development In 1948, a swept wing version of the F-84 was created with the hope of bringing performance to the level of the F-86. The last production F-84E was fitted with a swept tail, a new wing with 38.5 degrees of leading edge sweep and 3.5 degrees of anhedral, and a J35-A-25 engine producing 5,300 pound-force (23.58 kN) of thrust.Knaack 1978, p. 42. The aircraft was designated XF-96A. It flew on 3 June 1950 with Oscar P. Haas at the controls. Although the airplane was capable of 602 knots (693 mph, 1,115 km/h), the performance gain over the F-84E was considered minor. Nonetheless, it was ordered into production in July 1950 as the F-84F Thunderstreak. The F-84 designation was retained because the ...

Republic Aviation
The Republic Aviation Corporation was an American aircraft manufacturer based in Farmingdale, New York, on Long Island. Originally known as the Seversky Aircraft Company, the company was responsible for the design and production of many important military aircraft, including its most famous products: World War II's P-47 Thunderbolt fighter, the F-84 Thunderjet and F-105 Thunderchief jet fighters, as well as the A-10 Thunderbolt II close-support aircraft. History Seversky Aircraft The Seversky Aircraft Company was founded in 1931 by Alexander de Seversky, a Russian expatriate and veteran World War I pilot who had lost a leg in the war. In the beginning, many of Seversky Aircraft's designers were Russian and Georgian engineers, including Michael Gregor and Alexander Kartveli, who would go on to design many of Republic's most famous aircraft. After several failed attempts, Seversky Aircraft finally won a design competition for a new United States Army Air Corps fighter, and was awa ...

FICON Project
The FICON (Fighter Conveyor) program was conducted by the United States Air Force in the 1950s to test the feasibility of a Convair B-36 Peacemaker bomber carrying a Republic F-84 Thunderflash parasite fighter in its bomb bay. Earlier wingtip coupling experiments included Tip Tow, which were attempts at carrying fighters connected to the wingtips of bombers. Tom-Tom followed the FICON project afterwards. Background Wingtip coupling experiments Wingtip coupling experiments were evolved from the concept of adding extra floating panels to extend the effective wingspan of an aircraft, in the hope this would extend the range of the aircraft. This would theoretically act in the same manner as the long narrow wings of a glider. It is reported that the Germans experimented with the idea in 1944 and 1945 by coupling two equal-sized light planes together, then the idea was further developed by Richard Vogt, who came to the US from Germany after World War II. The idea was tested at Wrigh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yugoslav Air Force
The Air Force and Air Defence ( sh-Cyrl-Latn, Ратно ваздухопловство и противваздушна одбрана, Ratno vazduhoplovstvo i protivvazdušna odbrana ; abbr. sh-Cyrl-Latn, label=none, separator=/, РВ и ПВО, RV i PVO), was one of three branches of the Yugoslav People's Army, the Yugoslav military. Commonly referred-to as the Yugoslav Air Force, at its height it was among the largest in Europe. The branch was disbanded in 1992 after the Breakup of Yugoslavia. In the year 1990, the Air Force had more than 32,000 personnel, but as a result of its more technical requirements, the Air Force had less than 4,000 conscripts. History 1918–1941 World War II, Soviet influence By early 1945, Yugoslav Partisans under Marshal Tito had liberated a large portion of Yugoslav territory from the occupying forces.

Republic XF-84H Thunderscreech
The Republic XF-84H "Thunderscreech" was an American experimental turboprop aircraft derived from the F-84F Thunderstreak. Powered by a turbine engine that was mated to a supersonic propeller, the XF-84H had the potential of setting the unofficial air speed record for propeller-driven aircraft, but was unable to overcome aerodynamic deficiencies and engine reliability problems, resulting in the program's cancellation.Knaack, Marcelle Size. ''Encyclopedia of U.S. Air Force Aircraft and Missile Systems: Volume 1 Post-World War II Fighters 1945–1973''. Washington, D.C.: Office of Air Force History, 1978. . Design and development Although the USAF Wright Air Development Center was the key sponsor of the Republic Project 3347 turboprop fighter, the initial inception came from a U.S. Navy requirement for a carrier fighter not requiring catapult assistance.Keaveney 1987, p. 9. Originally known as XF-106 (a designation later reused for the Convair F-106), the project and its resultant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Republic XF-91 Thunderceptor
The Republic XF-91 Thunderceptor (originally designated XP-91) is a mixed-propulsion prototype interceptor aircraft, developed by Republic Aviation. The aircraft would use a jet engine for most flight, and a cluster of four small rocket engines for added thrust during climb and interception. The design was largely obsolete by the time it was completed due to the rapidly increasing performance of contemporary jet engines, and only two prototypes were built. One of these was the first American fighter to exceed Mach 1 in level flight. A unique feature of the Thunderceptor was its unusual inverse tapered wing, in which the chord length increased along the wing span from the root to the tip, the opposite of conventional swept wing designs. This was an attempt to address the problem of pitch-up, a potentially deadly phenomenon that plagued early high-speed models. The Thunderceptor's design meant the entire wing stalled smoothly, more like a straight-wing design. Design and develo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mark 7 Nuclear Bomb
Mark 7 "Thor" (or Mk-7') was the first tactical fission bomb adopted by US armed forces. It was also the first weapon to be delivered using the toss method with the help of the low-altitude bombing system (LABS). The weapon was tested in Operation Buster-Jangle. To facilitate external carry by fighter-bomber aircraft, Mark 7 was fitted with retractable stabilizer fins. The Mark 7 warhead (W7) also formed the basis of the BOAR rocket, the Mark 90 Betty nuclear depth charge, MGR-1 Honest John rocket, and MGM-5 Corporal ballistic missile. It was also supplied for delivery by Royal Air Force Canberra aircraft assigned to NATO in Germany under the command of SACEUR. This was done under the auspices of Project E, an agreement between the United States and the UK on the RAF carriage of US nuclear weapons. In UK use it was designated 1,650 lb. H.E. M.C. The Mark 7 was in service from 1952 to 1967(8) with 1700–1800 having been built. Design The Mark 7 was a variable yield fiss ...

Mikoyan-Gurevich MiG-15
The Mikoyan-Gurevich MiG-15 (russian: Микоя́н и Гуре́вич МиГ-15; USAF/DoD designation: Type 14; NATO reporting name: Fagot) is a jet fighter aircraft developed by Mikoyan-Gurevich for the Soviet Union. The MiG-15 was one of the first successful jet fighters to incorporate swept wings to achieve high transonic speeds. In aerial combat during the Korean War, it outclassed straight-winged jet day fighters, which were largely relegated to ground-attack roles. In response to the MiG-15’s appearance and in order to counter it, the United States Air Force rushed the North American F-86 Sabre to Korea.Thompson, Warren"Sabre: The F-86 in Korea."''Flight Journal'', December 2002. Retrieved: 30 June 2011. When refined into the more advanced MiG-17, the basic design would again surprise the West when it proved effective against supersonic fighters such as the Republic F-105 Thunderchief and McDonnell Douglas F-4 Phantom II in the Vietnam War of the 1960s.
