Yakovlev Yak-50 (1949)
Yakovlev Yak-50 was an early experimental turbojet interceptor aircraft designed in 1948 by the Yakovlev OKB in the USSR. The aircraft was essentially a stretched version of the Yakovlev Yak-30 (1948), with a more powerful engine and greater wing sweep. The Yak-50 is perhaps most significant as the first Yakovlev aircraft equipped with ''velosipednoye'' (bicycle) landing gear, a trademark of later Yakovlev designs. The Yak-50 designation was later reused for a propeller-driven aerobatic and trainer aircraft.Gunston, 1997 Development and design On February 21, 1949 a Sovmin order requested the Yakovlev OKB to design a lightweight, radar-equipped, all-weather and night interceptor capable of Mach 0.97 at 4,000 m (13,000 ft). The aircraft was to utilize the Klimov VK-1 engine which first appeared on Mikoyan-Gurevich MiG-15 and MiG-17 fighters. This engine was itself a Soviet copy of the British Rolls-Royce Nene centrifugal turbojet initially known as the RD-45. The leading fi ...

La-200
The Lavochkin La-200 (a.k.a. Aircraft 200) was a two-seater, swept winged, night/all-weather jet interceptor designed and manufactured by the Soviet Union's Lavochkin Design Bureau from 1948. Design and development In response to a requirement for a high performance night and all-weather interceptor, Lavochkin (OKB-310), Sukhoi ( OKB-134) and Mikoyan-Gurevich (OKB-155) design bureau developed the La-200, Su-15, and I-320 (where the I stands for ''Istrebitel'', or "Fighter") respectively. A key component of the three competing aircraft, was the "Toriy" ("Thorium") centimetre waveband NII-17 radar at Tikhomirnov NIIP - (NIIP for ''Nauchno-Issledovatel'skiy Institut Priborostroyeniya'', or "Research Institute of Instrument Engineering"), which was capable of detecting a Boeing B-29 Superfortress bomber at a range of . The La-200 was an all-metal, two seater, twin-engined jet aircraft, with a tricycle undercarriage and mid set wings with 40° sweep at 1/4 chord. The two Klimov ...

Dassault Mystère IV
The Dassault MD.454 Mystère IV is a 1950s French fighter-bomber aircraft, the first transonic aircraft to enter service with the French Air Force. It was used in large-scale combat in the Israeli Air Force during the 1967 Six Day War. Design and development The Mystère IV was an evolutionary development of the Mystère II aircraft. Although bearing an external resemblance to the earlier aircraft, the Mystère IV was in fact a new design with aerodynamic improvements for supersonic flight. The prototype first flew on 28 September 1952, and the aircraft entered service in April 1953. The first 50 Mystere IVA production aircraft were powered by British Rolls-Royce Tay turbojets, while the remainder had the French-built Hispano-Suiza Verdon 350 version of that engine. Operational history Israeli Mystère IVs saw action during the Arab–Israeli wars and were joined by the French Mystères for the Suez crisis. France France was the main operator of the Mystère IV and at the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dassault Mystère
The Dassault MD.452 Mystère is a 1950s French fighter-bomber. Development After the success of the Ouragan, Dassault was working on a more advanced machine which would take to the air in early 1951 as the MD.452 Mystère I. The first prototype Mystère I was essentially an Ouragan with a 30-degree swept wing and modified tail surfaces. Two further prototypes followed, powered by the Rolls-Royce Tay 250 centrifugal-flow turbojet, an improved version of the Rolls-Royce Nene, built under licence by Hispano-Suiza, and rated at thrust. These three Mystère I prototypes led to two Mystère IIA prototypes, powered by the Tay and armed with four Hispano cannon; and then four Mystère IIB prototypes, which traded the four cannon for two DEFA revolver-type cannon. A Mystère IIA was the first French aircraft to break Mach 1 in controlled flight (in a dive), on 28 October 1951. The eleven preproduction machines that followed were designated Mystère IIC, nine of which were fitt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
F-86D
The North American F-86D/K/L Sabre (initially known as the YF-95 and widely known informally as the "Sabre Dog",) was an American transonic jet fighter aircraft. Developed for the United States Air Force in the late 1940s, it was an interceptor derivative of the North American F-86 Sabre. While the original F-86 Sabre was conceived as a day fighter, the F-86D was specifically developed as an all-weather interceptor. Originally designated as the YF-95 during development and testing, it was re-designated the F-86D before production began, despite only sharing 25% commonality of parts with the original F-86. Production models of the F-86D/K/L differed from other Sabres in that they had a larger fuselage, a larger afterburning engine, and a distinctive nose radome. The most-produced Sabre Dog variants (the "D" and "G" models) also mounted no guns, unlike the Sabre with its six M3 Browning .50 caliber machine guns, instead mounting air-to-air rockets (the "K" and "L" Sabre Dog varian ...

F-94 Starfire
The Lockheed F-94 Starfire was a first-generation jet powered all-weather, day/night interceptor of the United States Air Force. A twin-seat craft, it was developed from the Lockheed T-33 Shooting Star trainer in the late 1940s. It reached operational service in May 1950 with Air Defense Command, replacing the piston-engined North American F-82 Twin Mustang in the all-weather interceptor role. The F-94 was the first operational USAF fighter equipped with an afterburner, and first jet-powered all-weather fighter to enter combat during the Korean War in January 1953. It had a relatively brief operational life, being replaced in the mid-1950s by the Northrop F-89 Scorpion and North American F-86D Sabre. The last aircraft left active-duty service in 1958 and Air National Guard service in 1959. Design and development Built to a 1948 USAF specification for a radar-equipped interceptor to replace the aging Northrop F-61 Black Widow and North American F-82 Twin Mustang, it was sp ...

Mikoyan-Gurevich MiG-17
The Mikoyan-Gurevich MiG-17 (russian: Микоян и Гуревич МиГ-17; NATO reporting name: Fresco) is a high-subsonic fighter aircraft produced in the Soviet Union from 1952 and was operated by air forces internationally. The MiG-17 was license-built in China as the Shenyang J-5 and Poland as the PZL-Mielec Lim-6. The MiG-17 is still being used by the North Korean air force in the present day and has seen combat in the Middle East and Asia. The MiG-17 was an advanced modification of the Mikoyan-Gurevich MiG-15, MiG-15 aircraft produced by the Soviet Union during the Korean War. Production of the MiG-17 was too late for use in that conflict and was first used in the Second Taiwan Strait Crisis in 1958. While the MiG-17 was designed to shoot down slower American bombers, it showed surprising success when used by North Vietnamese pilots to combat American fighters and fighter-bombers during the Vietnam War, nearly a decade after its initial design. This was due to the MiG ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yakolev Yak-140
The Yakovlev Yak-140 was a Soviet prototype lightweight supersonic fighter developed during the 1950s. The prototype was completed in 1954, but it was denied authorization to enter flight testing and the program was cancelled in 1956. Development The Yak-140 was developed around the Mikulin AM-11 turbojet (rated at thrust dry and with afterburner) to meet a specification issued in 1953 requiring a supersonic fighter with a maximum speed of and a range of . It was to be armed with three cannon with 75 rounds per gun and was to be capable of carrying air-to-ground rockets as well as of bombs. Its fully loaded weight was to be and it was to be ready to be submitted for State acceptance trials in March 1955.Gordon, et al., p. 190 The fighter had a circular-section semi-monocoque fuselage with a nose air intake. A range-only radar was fitted in the conical inlet cone of the air intake. The wings had a sweep angle of 55° at quarterchord. Two wing fences were fitted on the up ...

Nudelman-Rikhter NR-23
The Nudelman-Richter NR-23 is a Soviet autocannon widely used in military aircraft of the Soviet Union and Warsaw Pact. It was designed by A. E. Nudelman and A. A. Richter to replace the wartime Nudelman-Suranov NS-23 and Volkov-Yartsev VYa-23, entering service in 1949. The NR-23 is a single-barrel, short recoil-operated 23 mm (0.90 in) cannon. It was similar to the NS-23 but mechanical improvements increased its rate of fire by more than 50%. Its theoretical rate of fire was 850 rounds per minute, although United States Air Force tests of captured weapons achieved an actual rate of fire of only 650 rounds per minute. The NR-23 was later replaced by the Afanasev Makarov AM-23 automatic cannon which had a higher firing rate. The AM-23 was used in turreted installations for bombers. It was a gas-operated weapon, weighed 43 kg (95 lb) and was capable of a substantially higher rate of fire (1,200–1,300 rounds per minute). The People's Republic of China manuf ...

NACA Airfoil
The NACA airfoils are airfoil shapes for aircraft wings developed by the National Advisory Committee for Aeronautics (NACA). The shape of the NACA airfoils is described using a series of digits following the word "NACA". The parameters in the numerical code can be entered into equations to precisely generate the cross-section of the airfoil and calculate its properties. Origins NACA initially developed the numbered airfoil system which was further refined by the United States Air Force at Langley Research Center. According to the NASA website: Four-digit series The NACA four-digit wing sections define the profile by: # First digit describing maximum camber as percentage of the chord. # Second digit describing the distance of maximum camber from the airfoil leading edge in tenths of the chord. # Last two digits describing maximum thickness of the airfoil as percent of the chord. For example, the NACA 2412 airfoil has a maximum camber of 2% located 40% (0.4 chords) from the l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soviet Air Force
The Soviet Air Forces ( rus, Военно-воздушные силы, r=Voyenno-vozdushnyye sily, VVS; literally "Military Air Forces") were one of the air forces of the Soviet Union. The other was the Soviet Air Defence Forces. The Air Forces were formed from components of the Imperial Russian Air Service in 1917, and faced their greatest test during World War II. The groups were also involved in the Korean War, and dissolved along with the Soviet Union itself in 1991–92. Former Soviet Air Forces' assets were subsequently divided into several air forces of former Soviet republics, including the new Russian Air Force. "March of the Pilots" was its song. Origins The ''All-Russia Collegium for Direction of the Air Forces of the Old Army'' (translation is uncertain) was formed on 20 December 1917. This was a Bolshevik aerial headquarters initially led by Konstantin Akashev. Along with a general postwar military reorganisation, the collegium was reconstituted as the "Workers' ...

Yak-28
The Yakovlev Yak-28 (russian: Яковлев Як-28) is a swept wing, turbojet-powered combat aircraft used by the Soviet Union. Produced initially as a tactical bomber, it was also manufactured in reconnaissance, electronic warfare, interceptor, and trainer versions, known by the NATO reporting names Brewer, Brewer-E, Firebar, and Maestro respectively. Based on the Yak-129 prototype first flown on 5 March 1958, it began to enter service in 1960. Design and development The Yak-28 was firstTaylor 1976, pp. 520–521. seen by the West at the Tushino air show in 1961. Western analysts initially believed it to be a fighter rather than an attack aircraft—and a continuation of the Yak-25M—and it was designated "Flashlight". After its actual role was realized, the Yak-28 bomber series was redesignated "Brewer". The Yak-28 had a large mid-mounted wing, swept at 45 degrees. The tailplane set halfway up the vertical fin (with cutouts to allow rudder movement). Slats were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
