Sukhoi Su-15
The Sukhoi Su-15 (NATO reporting name: Flagon) is a twinjet supersonic interceptor aircraft developed by the Soviet Union. It entered service in 1965 and remained one of the front-line designs into the 1990s. The Su-15 was designed to replace the Sukhoi Su-11 and Sukhoi Su-9, which were becoming obsolete as NATO introduced newer and more capable strategic bombers. Development Recognizing the limitations of the earlier Su-9 and Su-11 in intercepting the new Boeing B-52 Stratofortress, particularly in terms of radar and aircraft performance, the Sukhoi OKB quickly began the development of a heavily revised and more capable aircraft. A variety of development aircraft evolved, including the Sukhoi T-49, which shared the fuselage of the Su-9 (including its single engine), but used cheek-mounted intakes to leave the nose clear for a large radome for the RP-22 Oryol-D ("Eagle") radar (NATO "Skip Spin"), and the T-5, essentially a heavily modified Su-11 with a widened rear fuselage ...

K-8 (missile)
The Kaliningrad K-8 (R-8) (NATO reporting name AA-3 'Anab') was a medium-range air-to-air missile developed by the Soviet Union for interceptor aircraft use.Gordon, Yefim. ''Soviet/Russian Aircraft Weapons''. Midland. 2004. The K-8 was developed by OKB-339/NII-339 (currently Phazotron, Phazotron NIIR). The infrared seeker was developed by TsKB-589 GKOT (currently TsKB Geofizika), who also developed the seeker for 9M31 missile of 9K31 Strela-1. History The K-8's development began in 1955, known as R-8 in service. Like most Soviet air-to-air missiles, it was made with a choice of semi-active radar homing or infrared homing, infrared seeker heads. The original missile was compatible with the Uragan-5B radar used on the Sukhoi Su-11 and several developmental aircraft from Mikoyan-Gurevich. It was upgraded to R-8M (better known as R-98) standard in 1961, giving the SARH weapon the capability for head-on intercepts. In 1963 it was further upgraded to the R-8M1, making it compatible wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radar
Radar is a system that uses radio waves to determine the distance ('' ranging''), direction ( azimuth and elevation angles), and radial velocity of objects relative to the site. It is a radiodetermination method used to detect and track aircraft, ships, spacecraft, guided missiles, motor vehicles, map weather formations, and terrain. The term ''RADAR'' was coined in 1940 by the United States Navy as an acronym for "radio detection and ranging". The term ''radar'' has since entered English and other languages as an anacronym, a common noun, losing all capitalization. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwave domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

MiG-25
The Mikoyan-Gurevich MiG-25 (; NATO reporting name: Foxbat) is a supersonic interceptor and reconnaissance aircraft that is among the fastest military aircraft to enter service. Designed by the Soviet Union's Mikoyan-Gurevich bureau, it is an aircraft built primarily using stainless steel. It was to be the last aircraft designed by Mikhail Gurevich, before his retirement. The first prototype flew in 1964 and the aircraft entered service in 1970. Although it was capable of reaching Mach 3.2+, this would result in the engines accelerating out of control and needing replacement, therefore the operational top speed was limited to Mach 2.83."Intelligence: Big-Mouth Belenko" ''Time'', 11 October 1976.

Typhoon
A typhoon is a tropical cyclone that develops between 180° and 100°E in the Northern Hemisphere and which produces sustained hurricane-force winds of at least . This region is referred to as the Northwestern Pacific Basin, accounting for almost one third of the world's tropical cyclones. For organizational purposes, the northern Pacific Ocean is divided into three regions: the eastern (North America to 140°W), central (140°W to 180°), and western (180° to 100°E). The Regional Specialized Meteorological Center (RSMC) for tropical cyclone forecasts is in Japan, with other tropical cyclone warning centres for the northwest Pacific in Hawaii (the Joint Typhoon Warning Center), the Philippines, and Hong Kong. Although the RSMC names each system, the main name list itself is coordinated among 18 countries that have territories threatened by typhoons each year. Within most of the northwestern Pacific, there are no official typhoon seasons as tropical cyclones form througho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blown Flaps
Blown flaps, blown wing or jet flaps are powered aerodynamic high-lift devices used on the wings of certain aircraft to improve their low-speed flight characteristics. They use air blown through nozzles to shape the airflow over the rear edge of the wing, directing the flow downward to increase the lift coefficient. There are a variety of methods to achieve this airflow, most of which use jet exhaust or high-pressure air bled off of a jet engine's compressor and then redirected to follow the line of trailing-edge flaps. ''Blown flaps'' may refer specifically to those systems that use internal ductwork within the wing to direct the airflow, or more broadly to systems like upper surface blowing or nozzle systems on conventional underwing engine that direct air through the flaps. Blown flaps are one solution among a broader category known as powered lift, which also includes various boundary layer control systems, systems using directed prop wash, and circulation control wings. ...

Delta Wing
A delta wing is a wing shaped in the form of a triangle. It is named for its similarity in shape to the Greek uppercase letter delta (letter), delta (Δ). Although long studied, the delta wing did not find significant practical applications until the Jet Age, when it proved suitable for high-speed Subsonic aircraft, subsonic and supersonic flight. At the other end of the speed scale, the Rogallo wing, Rogallo flexible wing proved a practical design for the hang glider and other ultralight aircraft. The delta wing form has unique aerodynamic characteristics and structural advantages. Many design variations have evolved over the years, with and without additional stabilising surfaces. General characteristics Structure The long root chord of the delta wing and minimal area outboard make it structurally efficient. It can be built stronger, stiffer and at the same time lighter than a swept wing of equivalent aspect ratio and lifting capability. Because of this it is easy and rela ...

Yakovlev Yak-25
The Yakovlev Yak-25 (List of NATO reporting names for fighters, NATO designation Flashlight-A/Mandrake) is a swept wing, turbojet-powered interceptor aircraft, interceptor and reconnaissance aircraft built by Yakovlev and used by the Soviet Union. Design and development The Yak-25 originated from a need for long-range Interceptor aircraft to protect the USSR's northern and eastern territory. The specification for a two-seat, twin-engine jet fighter and a related reconnaissance aircraft was issued by Joseph Stalin on 6 August 1951. Yak-120 Yakovlev began developing a two-seat, twin-engine patrol interceptor, designated the Yak-120 by the design bureau, in 1951. It received official authorization by a directive of the Council of Ministers of the Soviet Union, Council of Ministers on 10 August of that year. In a break from previous Yakovlev designs, the Yak-120's thin, mid-set wings were swept back at a 45 degree angle with large two-section flaps. To provide more directional s ...

Soviet Anti-Air Defense
The Soviet Air Defence Forces (; ) was the air defence branch of the Soviet Armed Forces. Formed in 1941, it continued being a service branch of the Russian Armed Forces after 1991 until it was merged into the Air Force in 1998. Unlike Western air defence forces, V-PVO was a branch of the military unto itself, separate from the Soviet Air Force (VVS) and Air Defence Troops of Ground Forces. During the Soviet period it was generally ranked third in importance of the Soviet services, behind the Strategic Rocket Forces and the Ground Forces. History Service during Second World War Preparations for creation of the air defence forces started in 1932, and by the beginning of Operation Barbarossa, June 1941, there were 13 PVO zones within the military districts. At the outbreak of war, air defence forces were in the midst of rearmament. Anti-aircraft artillery teams had few of the latest 37 mm automatic and 85 mm guns. Moreover, the troops were deficient in Yak-1s and MiG-3s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yakovlev Yak-28
The Yakovlev Yak-28 () is a swept wing, turbojet-powered combat aircraft used by the Soviet Union. Produced initially as a tactical medium 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 1964. 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 fitted on the leading edges an ...
