Polikarpov Ivanov
__NOTOC__ The Polikarpov Ivanov was a 1930s prototype Soviet ground attack monoplane designed by Polikarpov for a soviet government procurement competition codenamed Ivanov. Design The Ivanov was an all-metal low-wing monoplane with a retractable conventional landing gear and powered by a Shevtsov M-62 radial engine. It was fitted with four wing-mounted ShKAS machine guns with a moveable turret-mounted Berezin UBT fitted at the rear of the cockpit area. Development Two prototypes were under construction in 1938 and the first was tested from February to August 1938. The Ivanov was found to need better flying qualities and with the competing Kharkov R-10 already in production the second prototype was not completed and the programme was abandoned.

Polikarpov
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.

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 ...

Conventional Landing Gear
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 rudd ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shvetsov ASh-62
The Shvetsov ASh-62 (Russian: АШ-62, designated M-62 before 1941) is a nine-cylinder, air-cooled, radial aircraft engine produced in the Soviet Union. A version of this engine is produced in Poland as the ASz-62 and the People's Republic of China as the HS-5. Design and development The ASh-62 was a development of the Wright R-1820 Cyclone that had been built in Russia under licence as the Shvetsov M-25, the main improvements including a two-speed supercharger and a more efficient induction system. Power was increased from the Cyclone's 775 hp to 1,000 hp. First run in 1937, licensed versions are still in production by WSK "PZL-Kalisz" in Poland (as of 2017).Gruszczyński, Jerzy. ''W pierwszej lidze dostawców'', "Lotnictwo Aviation International" Nr. 9/2017, p. 34-37 (in Polish) The Ash-62 was also produced in China. It is estimated that 40,361 were produced in the USSR.

ShKAS Machine Gun
The ShKAS (Shpitalny-Komaritski Aviatsionny Skorostrelny, Shpitalny-Komaritski rapid fire for aircraft; Russian: ШКАС - Шпитального-Комарицкого Авиационный Скорострельный) is a 7.62 mm calibre machine gun widely used by Soviet aircraft in the 1930s and during World War II. The ShKAS had the highest rate of fire of any aircraft machine gun in general service during WWII. It was designed by Boris Shpitalniy and Irinarkh Komaritsky and entered production in 1934. ShKAS was used in the majority of Soviet fighters and bombers and served as the basis for the ShVAK cannon. Description ShKAS is a gas-operated revolver-type machine gun; it has a single chamber in which the pin strikes the primer. A key element of the ShKAS' high rate of fire is the revolving drum (feed cage) that holds ten rounds and provides a very smooth, progressive removal of the cartridges from their disintegrating link belt. The bolt locking action is Browning ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Berezin UB
The Berezin UB (russian: УБ - Универсальный Березина) (''Berezin's Universal'') was a 12.7 mm caliber Soviet aircraft machine gun widely used during World War II. Development In 1937, Mikhail Yevgenyevich Berezin began designing a new large-caliber aircraft machine gun chambered to the 12.7 mm round used by infantry machine guns. The new design passed factory trials in 1938 and was accepted into service in 1939 under the designation BS (Березин Синхронный, Berezin Sinkhronniy, Berezin Synchronized). The rate of fire made it well suited for use as defensive armament in aircraft. While a successful design, BS was not without its faults, the biggest being its cable-operated charging which required considerable physical strength. Continued development resulted in the improved UB which came in three versions: UBK (Крыльевой, Krylyevoi, for the wings), UBS (Синхронный, Sinkhronniy, Synchronized), and UBT (Турель ...

Kharkov KhAI-5
The Kharkiv KhAI-5, (sometimes Neman R-10) was a Soviet reconnaissance and light bomber aircraft, designed in the mid-1930s in the Kharkiv Aviation Institute (KhAI, - in Ukrainian: ХАІ), under the direction of Iosif Grigorevich Nyeman (sometimes written as Neman). Development The first prototype of the plane, with a factory designation KhAI-5 (ХАІ-5), flew in June 1936. Despite a lower performance, the aircraft won a contest against another reconnaissance plane design, the Kochyerigin R-9, and was accepted for a production with the military designation R-10 ('R' indicated ''razvyedchik'' meaning reconnaissance in Russian). It was a modern design for the time. 493 R-10s were manufactured in the Kharkiv and Saratov aviation plants by early 1940. The first series showed some teething problems, which resulted in Iosif Nyeman being arrested by the NKVD on December 11, 1938 under the accusation of sabotage and espionage, a common accusation at the time. In 1938 a variant, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tupolev ANT-51
The Sukhoi Su-2 (russian: Сухой Су-2) was a Soviet reconnaissance and light bomber aircraft used in the early stages of World War II. It was the first airplane designed by Pavel Sukhoi. The basic design received an engine and armament upgrade (Su-4) and was modified for the ground-attack role (ShB). Development In 1936, Joseph Stalin released a requirement for a multipurpose combat aircraft. Codenamed Ivanov, the airplane had to be capable of performing reconnaissance and then attacking the targets it located. P. O. Sukhoi was working in the Tupolev OKB at the time and designed the "Ivanov" aircraft under the tutelage of Andrei Tupolev. The resulting ANT-51 flew on 25 August 1937 with M. M. Gromov at the controls. Powered by a 610 kW (820 hp) Shvetsov M-62 air-cooled radial engine, the ANT-51 reached 403 km/h (220 kn, 250 mph) at 4,700 m (15,420 ft). This was considered insufficient but since the basic design was sound, it was decided ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1930s Soviet Attack Aircraft
Year 193 ( CXCIII) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Sosius and Ericius (or, less frequently, year 946 '' Ab urbe condita''). The denomination 193 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.
