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 fitt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tumansky R-11
The Tumansky R-11 (initially AM-11) was a Soviet Cold War-era turbojet engine. Design and development The Tumansky R-11 was developed by A.A. Mikulin, Sergei Tumansky, and B.S. Stechkin as a twin-spool axial-flow high-altitude non-afterburning turbojet for Yakovlev Yak-25RV reconnaissance aircraft. This engine was the first Soviet twin-spool turbojet. It was first run in early 1956Gunston 1989, p.167. and was later employed in some variants of the Yakovlev Yak-26 and Yakovlev Yak-27, as well as the Yak-28.Goebel, Greg"The Yakovlev Yak-25 & Yak-28."AirVectors. Retrieved: 17 July 2012. The R-11's basic design was very successful and it was later developed into the Tumansky R-13 and Tumansky R-25 along with the experimental Tumansky R-21. A total of 20,900 R-11 engines were built. Variants * R-11V-300 - first production version, high-altitude, non-afterburning * R-11F-300 (R-37F) - afterburning version, entered production in 1956, used on MiG-21F, P and U. * R-11AF-300 - impro ...

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 ...

Landing Gear
Landing gear is the undercarriage of an aircraft or spacecraft that is used for takeoff or landing. For aircraft it is generally needed for both. It was also formerly called ''alighting gear'' by some manufacturers, such as the Glenn L. Martin Company. For aircraft, Stinton makes the terminology distinction ''undercarriage (British) = landing gear (US)''. For aircraft, the landing gear supports the craft when it is not flying, allowing it to take off, land, and taxi without damage. Wheeled landing gear is the most common, with skis or floats needed to operate from snow/ice/water and skids for vertical operation on land. Faster aircraft have retractable undercarriages, which fold away during flight to reduce drag. Some unusual landing gear have been evaluated experimentally. These include: no landing gear (to save weight), made possible by operating from a catapult cradle and flexible landing deck: air cushion (to enable operation over a wide range of ground obstacles and wat ...

Soviet Air Forces
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' an ...

Ukrainian Air Force
The Ukrainian Air Force ( uk, Пові́тряні си́ли Збро́йних сил Украї́ни) is the air force of Ukraine and one of the five branches of the Armed Forces of Ukraine. Its headquarters are in the city of Vinnytsia. When the Soviet Union dissolved in 1991, many aircraft were left in Ukrainian territory. Ever since, the Ukrainian Air Force has been downsizing and upgrading its forces. The main inventory of the air force still consists of Soviet-made aircraft. As of 2007, 36,300 personnel and 225 aircraft were in service in the Ukrainian Air Force and Air Defense forces. Since Ukrainian independence in 1991, the air force has suffered from chronic underinvestment, leading to the bulk of its inventory becoming mothballed or otherwise inoperable. Despite this, Ukraine still possesses the world's 27th largest air force and the seventh largest air force in Europe, largely due to the ability of its domestic defense industry Ukroboronprom and its Antonov subsi ...

Tushino Air Show
In the life of Soviet Union, air shows were a highly regarded type of parade, almost always of military nature. They happened on various occasions and anniversaries, in many locations across the country. A notable air show was the Tushino Air Show held annually in August. Dates Soviet Air Fleet Day The most frequent date of air shows was the Soviet Air Fleet Day (russian: День Воздушного Флота). It was also known as the Soviet Air Forces Day (russian: День Военно-воздушных Сил), or Soviet Aviation Day.Pre-history of MAKS - provides the complete information on Russian and Soviet air shows.

Trainer Aircraft
A trainer is a class of aircraft designed specifically to facilitate flight training of pilots and aircrews. The use of a dedicated trainer aircraft with additional safety features—such as tandem flight controls, forgiving flight characteristics and a simplified cockpit arrangement—allows pilots-in-training to safely advance their skills in a more forgiving aircraft. Civilian pilots are normally trained in a light aircraft, with two or more seats to allow for a student and instructor. Tandem and side by side The two seating configurations for trainer aircraft are: pilot and instructor side by side, or in tandem, usually with the pilot in front and the instructor behind. The side-by-side seating configuration has the advantage that pilot and instructor can see each other's actions, allowing the pilot to learn from the instructor and the instructor to correct the student pilot. The tandem configuration has the advantage of being closer to the normal working environment that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RAF Gatow
Royal Air Force Gatow, or more commonly RAF Gatow, was a British Royal Air Force station (military airbase) in the district of Gatow in south-western Berlin, west of the Havel river, in the borough of Spandau. It was the home for the only known operational use of flying boats in central Europe, and was later used for photographic reconnaissance missions by de Havilland Canada DHC-1 Chipmunks over East Germany. Part of the former airfield is now called General Steinhoff-Kaserne, and is home to the Luftwaffenmuseum der Bundeswehr, the German Air Force Museum. Also on the site of the former Royal Air Force station, but not part of ''General Steinhoff-Kaserne'', is a school, the Hans-Carossa-Gymnasium, as well as houses for government employees of the Federal Republic of Germany. This part of the former airfield has since 2003 been part of the district of Berlin-Kladow.

Royal Navy
The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by English and Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the UK's armed services, it is consequently known as the Senior Service. From the middle decades of the 17th century, and through the 18th century, the Royal Navy vied with the Dutch Navy and later with the French Navy for maritime supremacy. From the mid 18th century, it was the world's most powerful navy until the Second World War. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superiority globally. Owing to this historical prominence, it is common, even among non-Britons, to ref ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
West Berlin
West Berlin (german: Berlin (West) or , ) was a political enclave which comprised the western part of Berlin during the years of the Cold War. Although West Berlin was de jure not part of West Germany, lacked any sovereignty, and was under military occupation until German reunification in 1990, the territory was claimed by the West Germany, Federal Republic of Germany (FRG) which was heavily disputed by the Soviet Union and other Eastern Bloc countries. However, West Berlin de facto aligned itself politically with the FRG on 23 May 1949, was directly or indirectly represented in its federal institutions, and most of its residents were citizens of the FRG. West Berlin was formally controlled by the Western Allies and entirely surrounded by the Soviet Union, Soviet-controlled East Berlin and East Germany. West Berlin had great symbolic significance during the Cold War, as it was widely considered by westerners an "island of free world, freedom" and America's most loyal counterpa ...

Mach Number
Mach number (M or Ma) (; ) is a dimensionless quantity in fluid dynamics representing the ratio of flow velocity past a boundary to the local speed of sound. It is named after the Moravian physicist and philosopher Ernst Mach. : \mathrm = \frac, where: : is the local Mach number, : is the local flow velocity with respect to the boundaries (either internal, such as an object immersed in the flow, or external, like a channel), and : is the speed of sound in the medium, which in air varies with the square root of the thermodynamic temperature. By definition, at Mach1, the local flow velocity is equal to the speed of sound. At Mach0.65, is 65% of the speed of sound (subsonic), and, at Mach1.35, is 35% faster than the speed of sound (supersonic). Pilots of high-altitude aerospace vehicles use flight Mach number to express a vehicle's true airspeed, but the flow field around a vehicle varies in three dimensions, with corresponding variations in local Mach number.
