Polikarpov ITP
The Polikarpov ITP (''Istrebitel Tyazholiy Pushechniy''; russian: Истребитель Тяжелый Пушечный; Heavy Cannon Fighter) was a Soviet fighter prototype designed during World War II. Development was prolonged by the evacuation of the design bureau forced by the German advance on Moscow in the fall of 1941. By the time the second prototype was finished the Soviets had fighters with equivalent or better performance already in production and the program was cancelled. Development In November 1940, Nikolai Polikarpov proposed a heavy cannon-armed fighter for bomber escort duties and ground attack missions. The new ITP was designed around either the 1,230 kW (1,650 hp) Klimov M-107P or the Mikulin AM-37 inline engines. Two armament configurations were planned. The first consisted of a cannon firing through the propeller hub and two synchronized ShVAK cannon mounted on each side of the fuselage nose. The 37 mm cannon was provided with 50 rounds ...

Soviet Union
The Soviet Union,. officially the Union of Soviet Socialist Republics. (USSR),. was a transcontinental country that spanned much of Eurasia from 1922 to 1991. A flagship communist state, it was nominally a federal union of fifteen national republics; in practice, both its government and its economy were highly centralized until its final years. It was a one-party state governed by the Communist Party of the Soviet Union, with the city of Moscow serving as its capital as well as that of its largest and most populous republic: the Russian SFSR. Other major cities included Leningrad (Russian SFSR), Kiev (Ukrainian SSR), Minsk ( Byelorussian SSR), Tashkent (Uzbek SSR), Alma-Ata (Kazakh SSR), and Novosibirsk (Russian SFSR). It was the largest country in the world, covering over and spanning eleven time zones. The country's roots lay in the October Revolution of 1917, when the Bolsheviks, under the leadership of Vladimir Lenin, overthrew the Russian Provisional Government ...

Leading Edge Slats
Slats are aerodynamic surfaces on the leading edge of the wing of a fixed-wing aircraft which, when deployed, allow the wing to operate at a higher angle of attack. A higher coefficient of lift is produced as a result of angle of attack and speed, so by deploying slats an aircraft can fly at slower speeds, or take off and land in shorter distances. They are used during takeoff and landing or while performing low speed maneuvers which may take the aircraft close to a stall, they are retracted in normal flight to minimize drag. Slats are one high-lift device used on high speed turbojet aircraft, trailing edge flap systems running along the trailing edge of the wing are common on all aircraft. Types Types include: ;Automatic: The spring-loaded slat lies flush with the wing leading edge, held in place by the force of the air acting on them. As the aircraft slows down, the aerodynamic force is reduced and the springs extend the slats. Sometimes referred to as Handley-Page slat ...

Polikarpov Aircraft
Polikarpov Design Bureau was a Soviet OKB (design bureau) for aircraft, led by Nikolai Nikolaevich Polikarpov. Dux Factory was acquired by the USSR and became part of Polikarpov. After the death of Polikarpov on 30 July 1944 at the age of 52, his OKB was absorbed into Lavochkin, but with some of its engineers going to Mikoyan-Gurevich and its production facilities going to Sukhoi. For a long time the Polikarpov OKB headquarters were located at Aircraft plant #1 (formerly Dux Factory) in Moscow, where its purpose-built building still stands. Designs Polikarpov designs: Bombers * TB-2 twin-engined biplane bomber prototype, 1930 * SPB (D) twin-engined dive bomber developed from the VIT-2, 1940 * NB (T) medium bomber prototype, 1944 Fighters * I-1 (IL-400) monoplane fighter prototype, 1923 * DI-1 (2I-N1) twin-seat biplane fighter prototype, 1926 * I-3 biplane fighter, 1928 * DI-2 two-seat biplane fighter developed from the I-3, 1929 * I-6 biplane fighter prototype, 1930 ...

1940s Soviet Fighter Aircraft
Year 194 ( CXCIV) was a common year starting on Tuesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Septimius and Septimius (or, less frequently, year 947 ''Ab urbe condita''). The denomination 194 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Roman Empire * Emperor Septimius Severus and Decimus Clodius Septimius Albinus Caesar become Roman Consuls. * Battle of Issus: Septimius Severus marches with his army (12 legions) to Cilicia, and defeats Pescennius Niger, Roman governor of Syria.

London
London is the capital and largest city of England and the United Kingdom, with a population of just under 9 million. It stands on the River Thames in south-east England at the head of a estuary down to the North Sea, and has been a major settlement for two millennia. The City of London, its ancient core and financial centre, was founded by the Romans as '' Londinium'' and retains its medieval boundaries.See also: Independent city § National capitals The City of Westminster, to the west of the City of London, has for centuries hosted the national government and parliament. Since the 19th century, the name "London" has also referred to the metropolis around this core, historically split between the counties of Middlesex, Essex, Surrey, Kent, and Hertfordshire, which largely comprises Greater London, governed by the Greater London Authority.The Greater London Authority consists of the Mayor of London and the London Assembly.

Yakovlev Yak-9
The Yakovlev Yak-9 (russian: Яковлев Як-9) is a single-engine, single-seat multipurpose fighter aircraft used by the Soviet Union and its allies during World War II and the early Cold War. It was a development of the robust and successful Yak-7B fighter, which was based in turn on the tandem-seat advanced trainer known as the Yak-7UTI. The Yak-9 started arriving in Soviet fighter regiments in late 1942 and played a major role in retaking air superiority from the Luftwaffe's new Focke-Wulf Fw 190 and fighters during the grand Battle of Kursk in summer 1943. The Yak-9 had a cut down rear fuselage with an unobscured canopy. Its lighter metal structure allowed for an increased fuel load and armament over previous models built from wood.Gustin 2003, p. 120. The Yak-9 was manoeuvrable at high speeds when flying at low and medium altitudes and was also easy to control, qualities that allowed it to be one of most produced Soviet fighters of World War II. It was produced in di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
V Engine
A V engine, sometimes called a Vee engine, is a common configuration for internal combustion engines. It consists of two cylinder banks—usually with the same number of cylinders in each bank—connected to a common crankshaft. These cylinder banks are arranged at an angle to each other, so that the banks form a "V" shape when viewed from the front of the engine. V engines typically have a shorter length than equivalent inline engines, however the trade-off is a larger width. V6, V8 and V12 engines are the most common layout for automobile engines with 6, 8 or 12 cylinders respectively. History The first V engine, a two-cylinder V-twin, was designed by Wilhelm Maybach and used in the 1889 Daimler Stahlradwagen automobile. The first V8 engine was produced in 1903, in the form of the Antoinette engine designed by Léon Levavasseur for racing boats and airplanes. The first V12 engine was produced the following year by Putney Motor Works in London, again for use in racing bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Polikarpov I-185
The Polikarpov I-185 was a Soviet fighter aircraft designed in 1940. It was flown with three engines but all of them were either insufficiently developed for service use or their full production was reserved for other fighters already in production. The I-185 program was cancelled on 27 January 1943. Design and development The I-185, designed in early 1940, was based on the I-180, which was itself a development of the I-16, but was virtually a new design. The monocoque fuselage was similarly built of 'shpon', molded birch plywood, and also had an integral fin, but it was considerably longer than that of the I-180. The two-spar, all-metal wing was smaller and thinner than the I-180's wing, nearly as thin as that of the Supermarine Spitfire's wing at 13% at the root and tapered to 8% at the wing tip. The wing had a NACA-230 profile and was skinned in duralumin. Pneumatically powered split flaps and leading edge slats were fitted. The outer wing panels had 3° of dihedral. The fa ...

Conventional Undercarriage
Conventional landing gear, or tailwheel-type landing gear, is an aircraft undercarriage consisting of two main wheels forward of the center of gravity and a small wheel or skid to support the tail.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 133. Aviation Supplies & Academics, 1997. From the Ground Up, 27th edition, page 11 The term taildragger is also used, although some argue it should apply only to those aircraft with a tailskid rather than a wheel. The term "conventional" persists for historical reasons, but all modern jet aircraft and most modern propeller aircraft use tricycle gear. History In early aircraft, a tailskid made of metal or wood was used to support the tail on the ground. In most modern aircraft with conventional landing gear, a small articulated wheel assembly is attached to the rearmost part of the airframe in place of the skid. This wheel may be steered by the pilot through a connection to the rudder pedals, allowing the rudder ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
