Sukhoi T-58
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 cont ...

Sukhoi T-49
The Sukhoi T-49 was a prototype Soviet fighter aircraft. Development The Sukhoi T-49 was a modernized version of the Sukhoi Su-11 with new radar and modified armament. The project was officially launched on August 6, 1957. The maiden flight of the T-49 prototype took place in January 1960, after various rolling tests in October 1959. In the development of the T-49, the delta wing, the tail and the cigar-shaped fuselage were taken from the Su-11. The entire fuselage in front of the cockpit has been redesigned to accommodate a more powerful radar. This extended the nose of the aircraft. Since this also gave the plane a larger diameter than the Su-11, it was no longer possible to accommodate the radar antenna in the shock cone of the air inlet. Therefore, lateral air inlets were constructed on both sides of the nose. This also simplified the operation of the radar, since its antenna was now firmly installed in the aircraft nose and the forward and backward movements of the engine ...

Typhoon
A typhoon is a mature tropical cyclone that develops between 180° and 100°E in the Northern Hemisphere. This region is referred to as the Northwestern Pacific Basin, and is the most active tropical cyclone basin on Earth, accounting for almost one-third of the world's annual 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 centers 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 thr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blown Flaps
Blown flaps, 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. Internal blow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 (Δ). Although long studied, it did not find significant applications until the Jet Age, when it proved suitable for high-speed subsonic and supersonic flight. At the other end of the speed scale, the 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 structure outboard make it structurally efficient. It can be built stronger, stiffer and at the same time lighter than a swept wing of equivalent lifting capability. Because of this it is easy and relatively inexpensive to build – a substantial factor in the success of the Mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Yakovlev Yak-25
The Yakovlev Yak-25 ( NATO designation Flashlight-A/Mandrake) was a swept wing, turbojet-powered 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 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 stability, a ventral fin was attached below the swept cruciform tail. The aircraft was powered by two Miku ...

Soviet Anti-Air Defense
The Soviet Air Defence Forces (russian: войска ПВО, ''voyska protivovozdushnoy oborony'', ''voyska PVO'', ''V-PVO'', lit. ''Anti-Air Defence Troops''; and formerly ''protivovozdushnaya oborona strany'', ''PVO strany'', lit. ''Anti-Air Defence of the Country'') 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 dis ...

Yakovlev 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 fitted ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
