Nikitin-Shevchenko IS
The Nikitin-Schyevchyenko IS series (, meaning "folding fighter"), were single seat wikt:polymorphic, polymorphic fighters designed and produced in the USSR from 1938. Development Nikitin's test pilot, Vladimir Vasiloyevich Schyevchyenko, investigated the practicality of a biplane fighter with a folding lower wing which retracted into the upper wing. The intention being to combine the short field length and climb capabilities of the biplane with the speed of the monoplane fighter. Assisted by Nikitin in his investigation, Schyevchyenko built a scale model at Moscow Art Theatre, MAT in 1939. Later in 1939 OKB-30 were tasked with the design and manufacture of the full-scale IS, which was completed by 6 November 1940. The fuselage forward of the cockpit, wing spar (aviation), spar booms and the combined lower inner wing and Landing gear, undercarriage assemblies were built up from welded 30KhGSA steel tubing, whilst the rest of the airframe was constructed from D16 duralumin thro ...

Polikarpov I-16
The Polikarpov I-16 () is a Soviet single-engine single-seat fighter aircraft of revolutionary design; it is a low-wing cantilever monoplane fighter with retractable landing gear, and the first such aircraft to attain operational status. It "introduced a new vogue in fighter design".Green, William. "Polikarpov's Little Hawk". ''Flying Review'', November 1969. The I-16 was introduced in the mid-1930s and formed the backbone of the Soviet Air Force at the beginning of World War II. The diminutive fighter, nicknamed "''Ishak''" or "''Ishachok''" ("donkey" or "burro") by Soviet pilots, figured prominently in the Second Sino-Japanese War,Liss 1966, p. 10. the Battle of Khalkhin Gol, Winter War and the Spanish Civil War – where it was called the ("rat") by the Nationalists or (" fly") by the Republicans. The Finns called the aircraft "(flying squirrel)". Design and development While working on the Polikarpov I-15 biplane, Nikolai Nikolaevich Polikarpov began desig ...

Polikarpov I-153
The Polikarpov I-153 ''Chaika'' () is a late 1930s Soviet sesquiplane fighter. Developed from the I-15 with a retractable undercarriage, the I-153 fought in the Soviet-Japanese combats in Mongolia and was one of the major Soviet fighter types in the early years of the Second World War. Three I-153s are still in flying condition. The I-153 is powered by the Shvetsov M-62 radial engine. Design and development In 1937, the Polikarpov design bureau carried out studies to improve on the performance of its I-15 and I-15bis biplane fighters without sacrificing manoeuvrability, as Soviet tactical doctrine was based on a mix of high performance monoplane fighters (met by the Polikarpov I-16) and agile biplanes.Gordon and Dexter 1999, p. 124. Early combat experience from the Spanish Civil War had shown that the I-16 had problems dealing with the Fiat CR.32 biplanes used by the Italian forces supporting the Nationalists, which suggested a need to continue the use of biplane fighters, ...

Makhonine Mak-10
The Makhonine Mak-10, was a variable-geometry research aircraft, built to investigate variable area / telescopic wings during 1931 in France. Design and development In the early 1930s several designers became interested in the possibility of changing the configuration of wings between take off and fast flight. Two routes were explored, the first primarily involving camber and hence lift coefficient reduction and the other a decrease of wing area by span reduction at high speed. The Schmeidler variable wing and that of the Gloster built Antoni- Breda Ba.15 were examples of the first group and the Makhonine Mak-10 of the second. Details of the Mak-10 are sparse but its novel feature was a telescopic wing which increased the span for take-off by or 60% of its high speed configuration. The outer panels retracted into the central ones, their inner ends supported on bearings rolling along one or more spars. The ends of the centre section were reinforced with cuffs. The wing apa ...

Berezin UB
The Berezin UB () (''Berezin's Universal'') was a 12.7 mm caliber Soviet aircraft machine gun widely used during World War II. Development In 1937, 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 (Турельный, Turelniy, for the turret), with UBS and UBK charged by compressed air. The UB w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tumansky M-88
The Tumansky M-88 was an air-cooled radial engine for aircraft developed in the Soviet Union shortly before World War II. Design and development The M-88 was designed to address the shortcomings of the Tumansky M-87. The improvements incorporated in the M-88 were a strengthened crankcase, crankshaft, connecting rods, waffle ribbing at the piston bottom and a two speed geared centrifugal supercharger. The M-88 retained the same bore/stroke and displacement as the M-87 while increasing power to 1,000-1,150 hp. Design work began in 1937 and by 1939 the first prototypes were being flight tested in the Polikarpov I-180 fighter prototypes. At first the M-88 was not a success, but the designers persisted and the M-88 was made into a reliable and widely produced engine. There were a number of different variants with the most numerous being the M-88B, of which 10,585 were produced at Zaporozhye and Omsk. The M-88B solved most of the mechanical failures associated with the M-8 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ShKAS
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 aircraft 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.
