FJ-3
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 ...

VF-121
VF-121 (Fighter Squadron 121) of the US Navy was a former Pacific Fleet Replacement Air Group (RAG) unit. Originally established on 1 July 1946, as VF-781, it was redesignated as VF-121 on 4 February 1953 and disestablished on 30 September 1980. On 11 April 1958 it changed duty from Fleet Squadron to Fleet Replacement Squadron and was later charged with the training of Navy F-4 Phantom flight and maintenance crews. Operational history Fighting Squadron On July 1, 1946, VF-781, ''The Pacemakers'' were stationed at Naval Air Station Los Alamitos. On 20 July 1950, VF-781 was based at NAS North Island. In January 1951 the squadron moved to NAS Miramar. VF-781 served on board with Air Group 102 (CVG-102) flying F9F-2B Panthers from 10 May to 17 December 1951. VF-781's next cruise was on board flying with Air Group 102 (CVG-102) flying F9F-5's over Korea from 15 September 1952 to 18 May 1953. On 18 November 1952, VF-781 scored its first MiG-15 kills by Royce Williams, John Midd ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North American FJ-4 Fury
The North American FJ-4 Fury is a swept-wing carrier-capable fighter-bomber for the United States Navy and Marine Corps. The final development in a lineage that included the Air Force's F-86 Sabre, the FJ-4 shared its general layout and engine with the earlier FJ-3, but featured an entirely new wing design and was a vastly different design in its final embodiment. Design and development Compared to that of the FJ-3, the FJ-4's new wing was much thinner, with a six percent thickness-to-chord ratio, and featured skin panels milled from solid alloy plates. It also had an increased area, and tapered more sharply towards the tips. Slight camber behind the leading edge improved low speed characteristics. The main landing gear design had to be considerably modified to fold wheel and strut within the contours of the new wing. The track of the main wheels was increased and because they were closer to the center of gravity, there was less weight on the nosewheel. Wing folding was limited t ...

Grumman F9F Cougar
The Grumman F9F/F-9 Cougar is a carrier-based fighter aircraft for the United States Navy and United States Marine Corps. Based on Grumman's earlier F9F Panther, the Cougar replaced the Panther's straight wing with a more modern swept wing. Thrust was also increased with the installation of a newer, more powerful engine. The Navy considered the Cougar an updated version of the Panther, despite having a different official name, and thus Cougars started off from F9F-6. Design and development Early development Rumors that the Soviet Union had produced a swept-wing fighter had circulated a year before the Mikoyan-Gurevich MiG-15 first appeared at air shows in 1949. Despite the level of activity taking place with swept-wing aircraft, the Navy was not initially focused on the development of such aircraft. This was largely because the Navy's focus at the time was defending the battle group against high speed, high altitude bombers with interceptors, as well as escorting medium-range ...

Navalised Aircraft
{{refimprove, date=February 2011 A navalised aircraft (or navalized aircraft) is an aircraft that has been specifically designed for naval use, in some cases as a variant of a land-based design. An aircraft based on an aircraft carrier is called carrier-based aircraft. Characteristics A navalised aircraft typically differs from its land-based equivalent by: * The airframe, engine and avionics are marinised against salt water corrosion. * It is designed to be used on a flight deck. For a fixed wing aircraft this typically means catapult attachment points, a tailhook and strengthened undercarriage. Naval helicopters usually have wheels rather than skids and may have mechanisms to attach to the deck. * It is designed to occupy minimum hangar space – for example the wings, tail-boom or rotors may fold. * There is enhanced protection against water ingress (including that from hosing down with fresh water to get rid of salt water). * Equipment such as sensors and weapons are o ...

AIM-9 Sidewinder
The AIM-9 Sidewinder (where "AIM" stands for "Air Intercept Missile") is a short-range air-to-air missile which entered service with the US Navy in 1956 and subsequently was adopted by the US Air Force in 1964. Since then the Sidewinder has proved to be an enduring international success, and its latest variants remain standard equipment in most Western-aligned air forces. The Soviet K-13 (AA-2 'Atoll'), a reverse-engineered copy of the AIM-9B, was also widely adopted by a number of nations. Low-level development started in the late 1940s, emerging in the early 1950s as a guidance system for the modular Zuni rocket. This modularity allowed for the introduction of newer seekers and rocket motors, including the AIM-9C variant, which used semi-active radar homing and served as the basis of the AGM-122 Sidearm anti-radar missile. Originally a tail-chasing system, early models saw extensive use during the Vietnam War but had a low success rate. This led to all-aspect capabilities in ...

North American Aviation
North American Aviation (NAA) was a major American aerospace manufacturer that designed and built several notable aircraft and spacecraft. Its products included: the T-6 Texan trainer, the P-51 Mustang fighter, the B-25 Mitchell bomber, the F-86 Sabre jet fighter, the X-15 rocket plane, the XB-70, the B-1 Lancer, the Apollo command and service module, the second stage of the Saturn V rocket, and the Space Shuttle orbiter. Through a series of mergers and sales, North American Aviation became part of North American Rockwell, which later became Rockwell International, and is now part of Boeing. History Early years On December 6, 1928, Clement Melville Keys founded North American as a holding company that bought and sold interests in various airlines and aviation-related companies. However, the Air Mail Act of 1934 forced the breakup of such holding companies. North American became a manufacturing company, run by James H. Kindelberger, James H. "Dutch" Kindelberger, who had bee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wright J65
The Wright J65 was an axial-flow turbojet engine produced by Curtiss-Wright under license from Armstrong Siddeley. A development of the Sapphire, the J65 powered a number of US designs. Design and development Curtiss-Wright purchased a license for the Sapphire in 1950, with plans to have the production lines running in 1951. However a series of delays due to design changes by Curtiss-Wright, such as substituting the Sapphire's machined midsection solid forged diffuser frame with a fabricated one of welded nodular iron, led to its service introduction slipping two years. The fabricated assembly, a more practicable production job with about one fifth the cost, was subsequently adopted for the Sapphire. Another change addressed the Sapphire's only major problem. The Sapphire was found to work well through the entire RPM range without the compressor stalling, which allowed it to dispense with inlet guide vanes or other solutions found on contemporary designs. However, in service it w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colt-Browning M3
The M2 machine gun or Browning .50 caliber machine gun (informally, "Ma Deuce") is a heavy machine gun that was designed towards the end of World War I by John Browning. Its design is similar to Browning's earlier M1919 Browning machine gun, which was chambered for the .30-06 cartridge. The M2 uses Browning's larger and more powerful .50 BMG (12.7 mm) cartridge. The design has had many designations; the official U.S. military designation for the current infantry type is Browning Machine Gun, Cal. .50, M2, HB, Flexible. It is effective against infantry, unarmored or lightly armored vehicles and boats, light fortifications, and low-flying aircraft. The gun has been used extensively as a vehicle weapon and for aircraft armament by the United States since the 1930s. It was heavily used during World War II, the Korean War, the Vietnam War, the Falklands War, the Soviet–Afghan War, the Gulf War, the Iraq War, and the War in Afghanistan. It is the primary heavy machine gun of NATO ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stall (fluid Mechanics)
In fluid dynamics, a stall is a reduction in the lift coefficient generated by a foil as angle of attack increases.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', p. 486. Aviation Supplies & Academics, 1997. This occurs when the critical angle of attack of the foil is exceeded. The critical angle of attack is typically about 15°, but it may vary significantly depending on the fluid, foil, and Reynolds number. Stalls in fixed-wing flight are often experienced as a sudden reduction in lift as the pilot increases the wing's angle of attack and exceeds its critical angle of attack (which may be due to slowing down below stall speed in level flight). A stall does not mean that the engine(s) have stopped working, or that the aircraft has stopped moving—the effect is the same even in an unpowered glider aircraft. Vectored thrust in aircraft is used to maintain altitude or controlled flight with wings stalled by replacing lost wing lift with engine or propeller thru ...
