Nudelman-Suranov NS-45
The Nudelman-Suranov NS-45 was an enlarged version of the Soviet Nudelman-Suranov NS-37 aircraft autocannon. It was evaluated for service on 44 Yakovlev Yak-9K aircraft during World War II, but proved to stress the airframes too much. The NS-45 was also mounted on the prototype Tupolev Tu-1 night fighter after the end of World War II. Design and development The NS-45 was created as a result of a July 1943 decision of the State Defense Committee to arm Soviet fighters with 45 mm autocannons. As with the 37 mm autocannons already installed in some Soviet and lend-lease single-engine fighters, the intended method of installation of the 45 mm gun was to have its barrel pass through the engine block and the empty propeller shaft, in this case that of the Yak-9. Consequently, the main difficulty in designing the 45 mm autocannon was the limitation imposed by the engine blocks available for this aircraft. Accounting for the diameter of the 45 mm shell, the Y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
USSR
The Union of Soviet Socialist Republics. (USSR), commonly known as the Soviet Union, was a List of former transcontinental countries#Since 1700, transcontinental country that spanned much of Eurasia from 1922 until Dissolution of the Soviet Union, it dissolved in 1991. During its existence, it was the list of countries and dependencies by area, largest country by area, extending across Time in Russia, eleven time zones and sharing Geography of the Soviet Union#Borders and neighbors, borders with twelve countries, and the List of countries and dependencies by population, third-most populous country. An overall successor to the Russian Empire, it was nominally organized as a federal union of Republics of the Soviet Union, national republics, the largest and most populous of which was the Russian SFSR.

Muzzle Brake
A muzzle brake or recoil compensator is a device connected to, or a feature integral (ported barrel) to the construction of, the muzzle or barrel of a firearm or cannon that is intended to redirect a portion of propellant gases to counter recoil and unwanted muzzle rise. Barrels with an integral muzzle brake are often said to be ported. The concept of a muzzle brake was first introduced for artillery. It was a common feature on many anti-tank guns, especially those mounted on tanks, in order to reduce the area needed to take up the strokes of recoil and kickback. They have been used in various forms for rifles and pistols to help control recoil and the rising of the barrel that normally occurs after firing. They are used on pistols for practical pistol competitions, and are usually called compensators in this context.STI article o ...

Heavy Fighter
A heavy fighter is an historic category of fighter aircraft produced in the 1930s and 1940s, designed to carry heavier weapons or operate at longer ranges than light fighter aircraft. To achieve performance, most heavy fighters were twin-engined, and many had multi-place crews; this was in contrast to light fighters, which were typically single-engined and single-crew aircraft. In Germany, these larger fighters were known as ''Zerstörer'' ("destroyers"). The heavy fighter was a major design class during the pre-World War II period, conceived as long-range escort fighters or heavily-armed bomber destroyers. Most such designs failed in this mission, as they could not maneuver quickly enough against single-engine fighters. Most notable among such designs was the Messerschmitt Bf 110, which suffered great losses during the Battle of Britain. An exception was the American Lockheed P-38 Lightning, which proved an effective heavy fighter; even against smaller, lighter, single-engin ...

Russian Aviation Regiment
An Aviation Regiment (, ''aviaciónnyj polk'') was a type of unit employed to organise aircraft and their crews in air combat in the Red Army Air Force during the Second World War, the Soviet Air Forces, Soviet Air Defence Forces (PVO) and Soviet Naval Aviation.p.34, Kozlov Since 1991 they remain major formations within the Russian Air Force and the Russian Naval Aviation. Aviation regiments were constituent units of the aviation divisions and aviation corps, and, the separate aviation regiment, as part of the Air Armies. Aviation regiments were homogeneously equipped with aircraft designed for specific operations, usually bomber, assault, fighter or reconnaissance types. The strength of aviation regiments varied significantly during Soviet-German fighting on the Eastern Front. Initially Fighter and assault air regiments consisted of four aviation squadrons of 15 aircraft each, for a total of 63 aircraft on their flight log. In the fighter regiment there were 78 pilots, in assa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soviet Air Forces
The Soviet Air Forces (, VVS SSSR; literally "Military Air Forces of the Union of Soviet Socialist Republics"; initialism VVS, sometimes referred to as the "Red Air Force") 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 Republics of the Soviet Union, Soviet republics, including the new Russian Air Force. The "Air March, March of the Pilots" was its marching song. Origins The first military aviation branch of Russia or any of the Soviet Union's constituent states was the short-lived Imperial Russian Air Service, founded in 1912 and disbanded in 1917 with the onset of the Bolshevik Revolution and ...

Prototype
A prototype is an early sample, model, or release of a product built to test a concept or process. It is a term used in a variety of contexts, including semantics, design, electronics, and Software prototyping, software programming. A prototype is generally used to evaluate a new design to enhance precision by system analysts and users. Prototyping serves to provide specifications for a real, working system rather than a theoretical one. Physical prototyping has a long history, and paper prototyping and virtual prototyping now extensively complement it. In some design workflow models, creating a prototype (a process sometimes called materialization) is the step between the Formal specification, formalization and the evaluation of an idea. A prototype can also mean a typical example of something such as in the use of the derivation prototypical. This is a useful term in identifying objects, behaviours and concepts which are considered the accepted norm and is analogous with terms ...

Messerschmitt Bf 109
The Messerschmitt Bf 109 is a monoplane fighter aircraft that was designed and initially produced by the Nazi Germany, German aircraft manufacturer Messerschmitt#History, Bayerische Flugzeugwerke (BFW). Together with the Focke-Wulf Fw 190, the Bf 109 formed the backbone of the ''Luftwaffe's'' fighter force during the World War II. It was commonly called the Me 109 by Allied aircrew and some German aces/pilots, even though this was not the official model designation. The Bf 109 was designed by Willy Messerschmitt and Robert Lusser, who worked at BFW during the early to mid-1930s. It was conceived as an interceptor aircraft, interceptor. However, later models were developed to fulfill multiple tasks, serving as Escort fighter, bomber escort, fighter-bomber, day fighter, day-, night fighter, night-, all-weather fighter, ground-attack aircraft, and aerial reconnaissance aircraft. It was one of the most advanced fighters when the fighter first appeared, being furnished with an all-me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Focke-Wulf Fw 190
The Focke-Wulf Fw 190, nicknamed ''Würger'' (Shrike) is a German single-seat, single-engine fighter aircraft designed by Kurt Tank at Focke-Wulf in the late 1930s and widely used during World War II. Along with its well-known counterpart, the Messerschmitt Bf 109, the Fw 190 became the backbone of the (Fighter Force) of the . The twin-row BMW 801 radial engine that powered most operational versions enabled the Fw 190 to lift larger loads than the Bf 109, allowing its use as a day fighter, fighter-bomber, ground-attack aircraft and to a lesser degree, night fighter. The Fw 190A started flying operationally over France in August 1941 and quickly proved superior in all but turn radius to the Supermarine Spitfire (early Merlin-powered variants)#Mk V (Mk V (Types 331, 349 and 352)), Spitfire Mk. V, the main front-line fighter of the Royal Air Force (RAF), particularly at low and medium altitudes. The 190 maintained its superiority over Allies of World War II, Allied fighters until ...
