Mikoyan-Gurevich I-224
The Mikoyan-Gurevich I-220 was a prototype high-altitude fighter aircraft built in the Soviet Union during World War II. Originally developed to counter the threat of German high-altitude reconnaissance aircraft, a total of seven prototypes were built and tested across five variants. By 1944, the threat of German high-altitude aircraft had subsided, and production of the I-220 and its variants was seen as unnecessary. Design and development In early 1941, the Soviet Union issued a requirement for a new high-altitude fighter aircraft to counter enemy high-altitude reconnaissance aircraft such as the Junkers Ju 86. However, it was not until late 1942 that a contract for two prototypes was placed with the Mikoyan and Gurevich OKB, which began work on ''Samolet'' A (Aircraft A). ''Samolet'' A, designated I-220 by the People's Commissariat of Aviation Industry (NKAP), was of an entirely new design of primarily ''shpon'' ( wood veneer) construction with a steel-tube truss engine m ...

Fighter Aircraft
Fighter aircraft are fixed-wing military aircraft designed primarily for air-to-air combat. In military conflict, the role of fighter aircraft is to establish air superiority of the battlespace. Domination of the airspace above a battlefield permits bombers and attack aircraft to engage in tactical and strategic bombing of enemy targets. The key performance features of a fighter include not only its firepower but also its high speed and maneuverability relative to the target aircraft. The success or failure of a combatant's efforts to gain air superiority hinges on several factors including the skill of its pilots, the tactical soundness of its doctrine for deploying its fighters, and the numbers and performance of those fighters. Many modern fighter aircraft also have secondary capabilities such as ground attack and some types, such as fighter-bombers, are designed from the outset for dual roles. Other fighter designs are highly specialized while still filling the ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mikulin AM-38
The Mikulin AM-38 was a 1940s Soviet aircraft piston engine. It was a further development of the Mikulin AM-35 design. The AM-38 was used on the Il-2 Shturmovik The Ilyushin Il-2 ( Russian: Илью́шин Ил-2) is a ground-attack plane that was produced by the Soviet Union in large numbers during the Second World War. The word ''shturmovík'' (Cyrillic: штурмовик), the generic Russian te ... and Il-10 ground attack aircraft. The AM-38 was installed experimentally in a MiG-3 and tested during August 1941. A slight performance improvement was seen at low-altitude but the engine experienced overheating problems due to the cooling and oil systems remaining unchanged from the AM-35A. Description The AM-38 was a low-altitude engine for ground attack aircraft that evolved from the earlier AM-35A. Compared to the AM-35A it had a reduced compression ratio, strengthened crankshaft, a single-speed geared centrifugal supercharger optimized for low-altitude perfor ...

V12 Engine
A V12 engine is a twelve-cylinder piston engine where two banks of six cylinders are arranged in a V configuration around a common crankshaft. V12 engines are more common than V10 engines. However, they are less common than V8 engines. The first V12 engine was built in 1904 for use in racing boats. Due to the balanced nature of the engine and the smooth delivery of power, V12 engines were found in early luxury automobiles, boats, aircraft, and tanks. Aircraft V12 engines reached their apogee during World War II, following which they were mostly replaced by jet engines. In Formula One racing, V12 engines were common during the late 1960s and early 1990s. Applications of V12 engines in the 21st century have been as marine engines, in railway locomotives, as large stationary power as well as in some European sports and luxury cars. Design Balance and smoothness Each bank of a V12 engine essentially functions as a straight-six engine, which by itself has perfect primary and ...

Yakovlev Yak-3
The Yakovlev Yak-3 (Russian: Яковлев Як-3) was a single-engine, single-seat World War II Soviet fighter. Robust and easy to maintain, it was much liked by both pilots and ground crew.Glancey 2006, p. 180. One of the smallest and lightest combat fighters fielded by any combatant during the war, its high power-to-weight ratio gave it excellent performance and it proved to be a formidable dogfighter. Origins The origins of the Yak-3 went back to 1941 when the I-30 prototype was offered along with the I-26 (Yak-1) as an alternative design. The I-30, powered by a Klimov M-105P engine, was of all-metal construction, using a wing with dihedral on the outer panels. Like the early Yak-1, it had a ShVAK cannon firing through the hollow-driveshaft nose spinner as a ''motornaya pushka'' (моторная пушка - Literally: 'Motor Cannon'), twin synchronized ShKAS machine guns in cowling mounts and a ShVAK cannon in each wing. During the Battle of Stalingrad, Luftwaffe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Klimov VK-107
The Klimov VK-107 was a V-12 liquid-cooled piston aircraft engine used by Soviet Union, Soviet aircraft during World War II. Development The VK-107 was developed from the Klimov M-105, M-105 and Klimov VK-106, VK-106. To achieve a greater power output, each cylinder now had four valves (two intake and two exhaust), crankshaft and camshafts were completely revised, and a new supercharger design was implemented. Although the engine could have been ready for production as early as 1942, the Soviet Union, Soviets' factories lacked the capacity to produce a brand new design. Thus, the less powerful Klimov VK-105PF and VK-105PF2 V12 engines were built instead. However, the appearance of Luftwaffe Messerschmitt Me 109, Messerschmitt Bf 109G with Daimler-Benz DB 605 engine in 1943 created an urgent demand for a more powerful engine. VK-107A was put into production in 1944 and was used on Yakovlev Yak-9, Yak-9U fighters. The engine was not well liked by either pilots or mechanics – it ha ...

Belly Landing
A belly landing or gear-up landing occurs when an aircraft lands without its landing gear fully extended and uses its underside, or belly, as its primary landing device. Normally the term ''gear-up landing'' refers to incidents in which the pilot forgets to extend the landing gear, while ''belly landing'' refers to incidents where a mechanical malfunction prevents the pilot from extending the landing gear. During a belly landing, there is normally extensive damage to the airplane. Belly landings carry the risk that the aircraft may flip over, disintegrate, or catch fire if it lands too fast or too hard. Extreme precision is needed to ensure that the plane lands as straight and level as possible while maintaining enough airspeed to maintain control. Strong crosswinds, low visibility, damage to the airplane, or unresponsive instruments or controls greatly increase the danger of performing a belly landing. Belly landings are one of the most common types of aircraft accidents neverthe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Khodynka Field
Khodynka Field (russian: Ходынское поле, ''Khodynskoye pole'') is a large open space in the north-west of Moscow, at the beginning of the present day Leningradsky Prospect. It takes its name from the small Khodynka River which used to cross the neighbourhood. The field is close to several Moscow Metro stations including Dinamo (Moscow Metro), Dinamo and Aeroport (Moscow Metro), Aeroport on the Zamoskvoretskaya Line, and Oktyabrskoe Pole on the Tagansko-Krasnopresnenskaya Line, which is named after Khodynka field. Early history Khodynka Field (up to the 17th century "Khodinskiy Meadow") has been known as such since the 14th century. The first mention of this name dates back to 1389, when Knyaz#Russia, Knyaz Dmitry Donskoy inheritance, bequeathed Khodyinsky Meadow to his son Yury of Zvenigorod, Yuri Dmitrievich. For a long time the field was undeveloped, placed it on arable land Tver coachmen settlement. At the beginning of the 17th century, the army of Tsar Vasili I ...

Mikulin AM-42
The Mikulin AM-42 was a 1940s Soviet aircraft piston engine designed by Alexander Mikulin. Representing a high-output version of the AM-38F, the AM-42 was used in the Ilyushin Il-1 fighter, and the Il-8 and Il-10 ground attack aircraft. Design and development The AM-42 was a low-altitude engine for attack aircraft that evolved from the earlier AM-38F. Compared to the AM-38F it had a reduced compression ratio, increased supercharging, strengthened and counterbalanced crankshaft, strengthened connecting rods, strengthened pistons and a revised oil system. The AM-42 was developed by the design bureau of Factory No. 24 now called the Salyut factory in Moscow. The first examples were produced in November 1942 and passed its 50-hour Factory tests in January 1943. In September 1943 the AM-42 began State tests but these were unfinished due to piston damage while testing. A strengthened version of the AM-42 completed its State tests in spring 1944. The AM-42 was produced in l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intercooler
An intercooler is a heat exchanger used to cool a gas after compression. Often found in turbocharged engines, intercoolers are also used in air compressors, air conditioners, refrigeration and gas turbines. Internal combustion engines Most commonly used with turbocharged engines, an intercooler is used to counteract the heat of compression and heat soak in the pressurised intake air. By reducing the temperature of the intake air, the air becomes denser (allowing more fuel to be injected, resulting in increased power) and less likely to suffer from pre-ignition or knocking. Additional cooling can be provided by externally spraying a fine mist onto the intercooler surface, or even into the intake air itself, to further reduce intake charge temperature through evaporative cooling. Intercoolers can vary dramatically in size, shape and design, depending on the performance and space requirements of the system. Many passenger cars use either ''front-mounted intercoolers'' l ...

NACA Airfoil
The NACA airfoils are airfoil shapes for aircraft wings developed by the National Advisory Committee for Aeronautics (NACA). The shape of the NACA airfoils is described using a series of digits following the word "NACA". The parameters in the numerical code can be entered into equations to precisely generate the cross-section of the airfoil and calculate its properties. Origins NACA initially developed the numbered airfoil system which was further refined by the United States Air Force at Langley Research Center. According to the NASA website: Four-digit series The NACA four-digit wing sections define the profile by: # First digit describing maximum camber as percentage of the chord. # Second digit describing the distance of maximum camber from the airfoil leading edge in tenths of the chord. # Last two digits describing maximum thickness of the airfoil as percent of the chord. For example, the NACA 2412 airfoil has a maximum camber of 2% located 40% (0.4 chords) from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
