Klimov M-105
The Klimov M-105 was a V12 engine, V12 Liquid-cooled engine, liquid-cooled piston aircraft engine used by Soviet Union, Soviet aircraft during World War II.Gunston 1989, p. 90 Development The M-105, designed in 1940, drew heavily on Klimov, Klimov's experience with the Hispano-Suiza 12Y (license-built as the M-100). In addition to a two-speed supercharger, the M-105 had several improvements like Multi-valve#Aircraft, two intake valves per cylinder and a counterbalanced crankshaft. The M-105 was the first Klimov V-12 engine design to use reverse-flow cylinder heads, forcing the induction system to be placed on the ''outside'' of the cylinder banks, with the exhaust system also exiting from the outboard side, with twin sets of "siamesed" exhaust ports adjacent to each other. About 129,000 M-105 and its variants were built. During the war, Klimov's engines were redesignated from "M" (for "motor," engine) to "VK" for the lead designer's initials. Variants * M-105 - () First version ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Supercharger
In an internal combustion engine, a supercharger compresses 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 supercharger is a form of forced induction that is mechanically powered (usually by a belt from the engine's crankshaft), as opposed to a turbocharger, which is powered by the kinetic energy of the exhaust gasses. However, up until the mid-20th century, a turbocharger was called a "turbosupercharger" and was considered a type of supercharger. The first supercharged engine was built in 1878, with usage in aircraft engines beginning in the 1910s and usage in car engines beginning in the 1920s. In piston engines used by aircraft, supercharging was often used to compensate for the lower air density at high altitudes. Supercharging is less commonly used in the 21st century, as manufacturers have shifted to turbochargers to reduce fuel consumption and/or increase power outputs. Des ...

Arkhangelsky Ar-2
The Arkhangelsky Ar-2 was a Soviet dive-bomber used in small numbers during World War II. Its design was a refinement of the earlier Russian Tupolev SB. The design bureau's name (Cyrillic: Архангельский) is transliterated in many ways in English sources, in a variety of combinations of Arch-, Arkh-, -sky, -ski, -skii, -skij). Development Alexander Arkhangelsky was already second in command at the Tupolev OKB when Andrei Tupolev was imprisoned in one of Stalin's purges. During Tupolev's absence, Arkhangelsky was authorised to append his name to the SB variants that were in the pipeline when he took over. The Ar-2 represented a final attempt to extend the useful lifespan of the SB design which had first flown in 1934. In early 1940, Arkhangelsky had worked on a refined SB, designated MMN, but this had proved disappointing, with performance no better than the original SB. The Ar-2 was therefore a greater departure from the Tupolev design, in the hopes of creating an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
P-39 Airacobra
The Bell P-39 Airacobra is a fighter produced by Bell Aircraft for the United States Army Air Forces during World War II. It was one of the principal American fighters in service when the United States entered combat. The P-39 was used by the Soviet Air Force, and enabled individual Soviet pilots to collect the highest number of kills attributed to any U.S. fighter type flown by any air force in any conflict. Other major users of the type included the Free French, the Royal Air Force, and the Italian Co-Belligerent Air Force.Gunston 1980, p. 22. It had an unusual layout, with the engine installed in the center fuselage, behind the pilot, and driving a tractor propeller in the nose with a long shaft. It was also the first fighter fitted with a tricycle undercarriage.Angelucci and Matricardi 1978, p. 25. Although its mid-engine placement was innovative, the P-39 design was handicapped by the absence of an efficient turbo-supercharger, preventing it from performing high-altitud ...

Propeller Speed Reduction Unit
A propeller speed reduction unit is a gearbox or a belt and pulley device used to reduce the output revolutions per minute (rpm) from the higher input rpm of the powerplant.Gunston 2006, p. 82. This allows the use of small displacement internal combustion engines to turn aircraft propellers within an efficient speed range. History and operation The Wright brothers recognised the need for propeller reduction gearing in 1903, but it was not generally used on aircraft engines until larger engines were designed in the 1920s. Large engines with high crankshaft speeds and power outputs demanded propeller reduction, pilots noted the increase in performance of similar aircraft fitted with reduction gearing. Types Types of propeller speed reduction units include: *Chain drive *Single reduction or spur gear *Internal spur gear *Farman or bevel planetary type *Fixed sun gear *Fixed internal gear *Belt drive *Epicyclic gearing Design variations The Rolls-Royce Falcon engine of 1915 fea ...

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 dif ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cylinder Bank
The engine configuration describes the fundamental operating principles by which internal combustion engines are categorized. Piston engines are often categorized by their cylinder layout, valves and camshafts. Wankel engines are often categorized by the number of rotors present. Gas turbine engines are often categorized into turbojets, turbofans, turboprops and turboshafts. Piston engines Piston engines are usually designed with the cylinders in lines parallel to the crankshaft. It is called a straight engine (or 'inline engine') when the cylinders arranged in a single line. Where the cylinders are arranged in two or more lines (such as in V engines or flat engines), each line of cylinders is referred to as a 'cylinder bank'. The angle between cylinder banks is called the 'bank angle'. Engines with multiple banks are shorter than straight engines and can be designed to cancel out the unbalanced forces from each bank, in order to reduce the vibration. Most engines with fou ...

Autocannon
An autocannon, automatic cannon or machine cannon is a fully automatic gun that is capable of rapid-firing large-caliber ( or more) armour-piercing, explosive or incendiary shells, as opposed to the smaller-caliber kinetic projectiles (bullets) fired by a machine gun. Autocannons have a longer effective range and greater terminal performance than machine guns, due to the use of larger/heavier munitions (most often in the range of , but bigger calibers also exist), but are usually smaller than tank guns, howitzers, field guns or other artillery. When used on its own, the word "autocannon" typically indicates a non-rotary weapon with a single barrel. When multiple rotating barrels are involved, such a weapon is referred to as a "rotary autocannon" or occasionally "rotary cannon", for short (particularly on aircraft). Autocannons are heavy weapons that are unsuitable for use by infantry. Due to the heavy weight and recoil Recoil (often called knockback, kickback o ...
