Tu-16 Rear
The Tupolev Tu-16 (NATO reporting name: Badger) is a twin-engined jet strategic heavy bomber used by the Soviet Union. It has been flown for almost 70 years, and the Chinese license-built Xian H-6 remains in service with the People's Liberation Army Air Force. Development In the late 1940s, the Soviet Union was strongly committed to matching the United States in strategic bombing capability. The Soviets' only long-range bomber at the time was Tupolev's Tu-4 'Bull', a reverse-engineered copy of the American B-29 Superfortress. The development of the notably powerful Mikulin AM-3 turbojet led to the possibility of a large, jet-powered bomber. The Tupolev design bureau began work on the Tu-88 ("Aircraft N") prototypes in 1950. The Tu-88 first flew on 27 April 1952. After winning a competition against the Ilyushin Il-46, it was approved for production in December 1952. The first production bombers entered service with Frontal Aviation in 1954, receiving the service designation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000".

Grand Slam (bomb)
The Bomb, Medium Capacity, (Grand Slam) was a earthquake bomb used by RAF Bomber Command against German targets towards the end of the Second World War. The bomb was originally called Tallboy Large until the term Tallboy got into the press and the code name was replaced by "Grand Slam". The bomb was similar to a large version of the Tallboy bomb but a new design and closer to the size that its inventor, Barnes Wallis, had envisaged when he developed the idea of an earthquake bomb. Medium Capacity (M.C.) bombs were designed to remedy the shortcomings of General Purpose (G.P.) bombs, with a greater blast and casings which were robust enough to confer a considerable capacity to penetrate, especially the Tallboy and Grand Slam. The Grand Slam case was made of a chrome-molybdenum alloy steel and had a charge-to-weight ratio of over 43 per cent. Conventional Avro Lancaster bombers could not carry the bomb and 32 Lancaster B.Mk 1 (Special)s with more powerful engines, a stronger und ...

Swept Wing
A swept wing is a wing that angles either backward or occasionally forward from its root rather than in a straight sideways direction. Swept wings have been flown since the pioneer days of aviation. Wing sweep at high speeds was first investigated in Germany as early as 1935 by Albert Betz and Adolph Busemann, finding application just before the end of the Second World War. It has the effect of delaying the shock waves and accompanying aerodynamic drag rise caused by fluid compressibility near the speed of sound, improving performance. Swept wings are therefore almost always used on jet aircraft designed to fly at these speeds. The term "swept wing" is normally used to mean "swept back", but variants include forward sweep, variable sweep wings and oblique wings in which one side sweeps forward and the other back. The delta wing is also aerodynamically a form of swept wing. Reasons for sweep There are three main reasons for sweeping a wing: 1. to arrange the center of gravity ...

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' an ...

Ilyushin Il-46
__NOTOC__ The Ilyushin Il-46 was a jet-engined bomber produced in the USSR during 1951-2, as the result of a directive to redesign the Il-42 project (half the drawings had already been completed). The revised specification was for an aircraft with twice the range and 1 1/2 times the bomb load, with a prototype ready to be submitted for state acceptance trials in July 1952. The Ilyushin design bureau set about designing two versions of the same aircraft, the straight-wing (Il-46) and the swept-wing (Il-46S), with as much as possible common to both aircraft. To meet the schedule for state acceptance trials Ilyushin built only the straight-wing version, fearing that the design, manufacture and flying characteristics of the swept-wing aircraft might cause delays. Design and development The airframe, constructed of aluminium alloy with steel used in highly stressed parts, resembled a large Il-28, the long fuselage having swept tail surfaces, and a similar arrangement of cockpits for ...

Turbojet
The turbojet is an airbreathing jet engine which is typically used in aircraft. It consists of a gas turbine with a propelling nozzle. The gas turbine has an air inlet which includes inlet guide vanes, a compressor, a combustion chamber, and a turbine (that drives the compressor). The compressed air from the compressor is heated by burning fuel in the combustion chamber and then allowed to expand through the turbine. The turbine exhaust is then expanded in the propelling nozzle where it is accelerated to high speed to provide thrust. Two engineers, Frank Whittle in the United Kingdom and Hans von Ohain in Germany, developed the concept independently into practical engines during the late 1930s. Turbojets have poor efficiency at low vehicle speeds, which limits their usefulness in vehicles other than aircraft. Turbojet engines have been used in isolated cases to power vehicles other than aircraft, typically for attempts on land speed records. Where vehicles are "turbine-powere ...

Mikulin AM-3
The Mikulin AM-3 (also called RD-3M) was a turbojet engine developed in the Soviet Union by Alexander Mikulin.Gunston 1989, p. 104. Design and development The development of the high-performance single-shaft engine began in 1948. The engine was used in different versions for the Tupolev Tu-16 and Tu-104, as well as the Myasishchev M-4. It had a single-stage low-pressure and an eight-stage high-pressure compressor, powered by a two-stage high-pressure turbine. Variants ;AM-3: first series version ;AM-3A: ;AM-3D: Version for M-4 with thrust ;AM-3M-200: AM-3M-500, AM-3M-500A: developed further versions with ;WP-8: Chinese copy of the AM-3 with thrust for the Xian H-6 The Xian H-6 () is a twin-engine jet bomber of the Chinese People's Liberation Army Air Force (PLAAF).

B-29 Superfortress
The Boeing B-29 Superfortress is an American four-engined propeller-driven heavy bomber, designed by Boeing and flown primarily by the United States during World War II and the Korean War. Named in allusion to its predecessor, the B-17 Flying Fortress, the Superfortress was designed for high-altitude strategic bombing, but also excelled in low-altitude night incendiary bombing, and in dropping naval mines to blockade Japan. B-29s dropped the atomic bombs on Hiroshima and Nagasaki, the only aircraft ever to drop nuclear weapons in combat. One of the largest aircraft of World War II, the B-29 was designed with state-of-the-art technology, which included a pressurized cabin, dual-wheeled tricycle landing gear, and an analog computer-controlled fire-control system that allowed one gunner and a fire-control officer to direct four remote machine gun turrets. The $3 billion cost of design and production (equivalent to $ billion today), far exceeding the $1.9 b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reverse Engineering
Reverse engineering (also known as backwards engineering or back engineering) is a process or method through which one attempts to understand through deductive reasoning how a previously made device, process, system, or piece of software accomplishes a task with very little (if any) insight into exactly how it does so. It is essentially the process of opening up or dissecting a system to see how it works, in order to duplicate or enhance it. Depending on the system under consideration and the technologies employed, the knowledge gained during reverse engineering can help with repurposing obsolete objects, doing security analysis, or learning how something works. Although the process is specific to the object on which it is being performed, all reverse engineering processes consist of three basic steps: Information extraction, Modeling, and Review. Information extraction refers to the practice of gathering all relevant information for performing the operation. Modeling refers to th ...
