Sukhoi Su-6
The Sukhoi Su-6 was a Soviet ground-attack aircraft developed during World War II. The mixed-power (rocket and piston engines) high-altitude interceptor Su-7 was based on the single-seat Su-6 prototype. Design and development Development of the Su-6 began in 1939, when the Sukhoi design bureau began work on a single-seat armoured ground-attack aircraft. An order for two prototypes was placed on 4 March 1940, and on 1 March 1941 flight testing of the first prototype was begun by test pilot A.I. Kokin. The flight tests indicated that the Su-6 was superior to the Ilyushin Il-2 in nearly all performance categories, however its engine exceeded its age limit before testing could be completed, and no further Shvetsov M-71 engines were available. The second prototype flew only in January 1942 because the OKB had to be evacuated after the start of the Great Patriotic War. It was armed with two 23 mm cannon, four machine guns and ten rails for aerial rockets. Test results were very ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Turbocharger
In an internal combustion engine, a turbocharger (often called a turbo) is a forced induction device that is powered by the flow of exhaust gases. It uses this energy to compress the intake gas, forcing more air into the engine in order to produce more power for a given displacement. The current categorisation is that a turbocharger is powered by the kinetic energy of the exhaust gasses, whereas a supercharger is mechanically powered (usually by a belt from the engine's crankshaft). However, up until the mid-20th century, a turbocharger was called a "turbosupercharger" and was considered a type of supercharger. History Prior to the invention of the turbocharger, |
Nudelman-Suranov NS-37
The Nudelman-Suranov NS-37 (russian: Нудельман - Суранов НС-37) was a aircraft cannon, which replaced the unreliable Shpitalny Sh-37 gun. Large caliber was planned to allow destruction of both ground targets (including armoured ones) and planes (ability to shoot down a bomber with a single hit). Developed by Alexander Nudelman, A. E. Nudelman and A. Suranov from OKB-16 Construction Bureau from 1941, it was tested at the front in 1943 and subsequently ordered into production, which lasted until 1945. It was used on the LaGG-3 and Yakovlev Yak-9, Yak-9T fighter planes (mounted between the vee of the engine, in ''motornaya pushka'' mounts) and Ilyushin Il-2, Il-2 ground attack planes (in underwing pods). Although the heavy round offered large firepower, the relatively low rate of fire and heavy recoil made hitting targets difficult. While pilots were trained to fire short bursts, on light aircraft only the first shot was truly aimed. Additionally, penetration of m ...

RS-132
RS-82 and RS-132 (Reaktivny Snaryad; Russian: Реактивный Снаряд; rocket-powered projectile) were unguided rockets used by Soviet military during World War II. Development Design work on RS-82 and RS-132 rockets began in the late 1920s, by the Gas Dynamics Laboratory (GDL) led by Georgy Langemak, and including Nikolai Tikhomirov, Vladimir Artemiev, Boris Petropavlovsky, Yuriy Pobedonostsev, and others. The 82 mm (3.2 in) and 132 mm (5.2 in) diameters were chosen because the standard smokeless gunpowder charge used at the time was 24 mm (0.94 in) in diameter and seven of these charges fitted into an 82 mm cylinder. The first test-firing of a solid fuel rocket was carried out in March 1928, which flew for about 1,300 meters and in 1932 in-air test firings of RS-82 missiles from an Tupolev I-4 aircraft armed with six launchers successfully took place. In 1933 GDL became part of the Reactive Scientific Research Institute, where developm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shvetsov M-71F
The Shvetsov M-71 was a Soviet radial engine built in small numbers during World War II. It was derived from the Shvetsov M-25, which was a license-built copy of the American Wright R-1820-F3 Cyclone engine. Development The M-71 was developed from the Shvetsov M-70, a failed attempt at a two-row version of the single-row Wright R-1820 Cyclone. It used components from the Shvetsov M-63, which was an improved version of the M-25 with more horsepower than the original. Development began at the beginning of 1939 and it was bench tested that August, but did not pass its State acceptance tests until the autumn of 1942. It weighed and produced . It was flight-tested in a Polikarpov I-185 prototype fighter in March–April 1942. A boosted version, the M-71F, was built in small numbers. It was flown in the prototypes of the single-engined Sukhoi Su-6 and the twin-engined Sukhoi Su-8 ground-attack aircraft in 1943–44 as well as the Lavochkin La-7 fighter in 1944. A version of the M- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Berezin UBT
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 ...

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.
