Yak-7
The Yakovlev Yak-7 (; NATO reporting name: Mark)Jane's All the World's Aircraft 1955-56 p. 188 was developed from the earlier Yak-1 fighter, initially as a trainer but converted into a fighter. As both a fighter and later reverting to its original training role, the Yak-7 proved to be a capable aircraft and was well liked by air crews. The Yak-7 was simpler, tougher and generally better than the Yak-1.Taylor 1985, p. 122. Design and development In 1939, Alexander Yakovlev designed a tandem-seat advanced trainer, originally designated "I-27" and then "UTI-26", offered along with the original I-26 proposal that became the Yak-1. The "UTI" (''Uchebno Trenirovochnyi Istrebitel'', translated as: Training Fighter) was intended to give pilots-in-training experience on a high-performance aircraft before transitioning to a fighter. With development work started in 1940, the UTI-26 differed from its predecessor in its larger span wing being placed farther back for balance as well as hav ...

Yakovlev Yak-1
The Yakovlev Yak-1 () was a Soviet fighter aircraft of World War II. The Yak-1 was a single-seat monoplane with a composite structure and wooden wings; production began in early 1940.Angelucci and Matricardi 1978, p. 239. The Yak-1 was a maneuverable, fast and competitive fighter aircraft. The composite-wooden structure made it easy to maintain and the engine proved to be reliable.Snedden 1997, p. 71. It formed the basis for subsequent developments from the Yakovlev bureau and was the founder of a family of aircraft, with some 43,000 being built.Gunston 1998, p. 88.Ethell 1995, p. 163. As a reward, designer Alexander Yakovlev was awarded the Order of Lenin ( Russian: ) (the highest civilian decoration bestowed by the Soviet Union), a 100,000 ruble prize, and a ZIS motor car.Jackson 2003, p. 160.Matricardi 2006, p. 77.

Yakovlev Yak-9
The Yakovlev Yak-9 (; NATO reporting name: Frank) 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 Messerschmitt Bf 109 fighters during the 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 the most produced Soviet fighters of World War II. It wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alexander Sergeevich Yakovlev
Alexander Sergeyevich Yakovlev (; 22 August 1989) was a Soviet aeronautical engineer. He designed the Yakovlev military aircraft and founded the Yakovlev Design Bureau. Yakovlev joined the Communist Party of the Soviet Union in 1938. Biography Yakovlev was born in Moscow, where his father was an employee of the Nobel Brothers oil company. From 1919 to 1921, he worked as a part-time courier while still in school, and in 1922 he built his first model aeroplane as part of a school project. In 1924, he built a glider, the AVF-10, which made its first flight on 24 September 1924. The design won an award and secured him a position as a worker at the Zhukovsky Air Force Military Engineering Academy. However, his repeated attempts to gain admission to the Academy were denied due to his “lack of proletariat origins”. In 1927, Yakovlev designed the AIR-1 ultralight aircraft. This was the first of ten aircraft he designed between 1927 and 1933. In 1927, Yakovlev finally gained admit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lavochkin-Gorbunov-Gudkov LaGG-3
The Lavochkin-Gorbunov-Gudkov LaGG-3 (Лавочкин-Горбунов-Гудков ЛаГГ-3) was a Soviet fighter aircraft of World War II. It was a refinement of the earlier LaGG-1 and was one of the most modern aircraft available to the Soviet Air Force at the time of Germany's invasion in 1941. Compared to its opponents the LaGG-3 was underpowered and, despite its wooden construction, overweight. It was unpopular with Soviet pilots, but despite this, at one point in the war, on average 12 LaGG-3s were being completed daily and 6,528 had been built in total when production switched to the Yak-3 in 1944. The LaGG-3 was steadily improved, forming the basis for the more successful La-5 and La-7. Design and development The prototype of the LaGG-3 was called the I-301 and was designed by Semyon A. Lavochkin, and . The prototype was later renamed the LaGG-1 and production aircraft were called the LaGG-3. The prototype was designed and produced by the GAZ-301 factory in Khim ...

ShVAK Cannon
The ShVAK (, "Shpitalny-Vladimirov Aviation Large-calibre") was a 20 mm autocannon used by the Soviet Union during World War II. It was designed by Boris Shpitalniy and Semyon Vladimirov and entered production in 1936. ShVAK were installed in many models of Soviet aircraft. The TNSh was a version of the gun produced for light tanks (). ShVAK shares the name with its 12.7 mm heavy machine gun predecessor. Development and production 12.7x108mm ShVAK The development of the 12.7 mm ShVAK was in response to a Soviet government decree passed on 9 February 1931, directing domestic manufacturers to produce an aircraft machine gun for the 12.7×108mm cartridge that had been introduced a couple of years prior for the DK machine gun. Tula designer S.V. Vladimirov answered the call by producing basically an enlarged version of the ShKAS, with a 1246 mm long barrel and a total length of 1726 mm. The first prototype was ready for trials on May 28, 1932. The testing pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Propeller (aircraft)
In aeronautics, an aircraft propeller, also called an airscrew,Beaumont, R.A.; ''Aeronautical Engineering'', Odhams, 1942, Chapter 13, "Airscrews". converts rotary motion from an engine or other power source into a swirling slipstream which pushes the propeller forwards or backwards. It comprises a rotating power-driven hub, to which are attached several radial airfoil-section blades such that the whole assembly rotates about a longitudinal axis. The blade pitch may be fixed, manually variable to a few set positions, or of the automatically variable "constant-speed" type. The propeller attaches to the power source's driveshaft either directly or through reduction gearing. Propellers can be made from wood, metal or composite materials. Propellers are most suitable for use at subsonic airspeeds generally below about , although supersonic speeds were achieved in the McDonnell XF-88B experimental propeller-equipped aircraft. Supersonic tip-speeds are used in some aircraft like the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landing Gear
Landing gear is the undercarriage of an aircraft or spacecraft that is used for taxiing, takeoff or landing. For aircraft, it is generally needed for all three of these. It was also formerly called ''alighting gear'' by some manufacturers, such as the Glenn L. Martin Company. For aircraft, Stinton makes the terminology distinction ''undercarriage (British) = landing gear (US)''. For aircraft, the landing gear supports the craft when it is not flying, allowing it to take off, land, and taxi without damage. Wheeled landing gear is the most common, with skis or Seaplane, floats needed to operate from snow/ice/water and skids for vertical operation on land. Retractable undercarriages fold away during flight, which reduces drag (physics), drag, allowing for faster airspeeds. Landing gear must be strong enough to support the aircraft and its design affects the weight, balance and performance. It often comprises three wheels, or wheel-sets, giving a tripod effect.

Mikoyan-Gurevich MiG-3
The Mikoyan-Gurevich MiG-3 () is a Soviet fighter-interceptor used during World War II. It was a development of the MiG-1 by the OKO (opytno-konstruktorskij otdel — Experimental Design Department) of Zavod (Factory) No. 1 in Moscow to remedy problems found during the MiG-1's development and operations. It replaced the MiG-1 on the production line at Factory No. 1 on 20 December 1940 and was built in large numbers during 1941 before Factory No. 1 was converted to build the Ilyushin Il-2. On 22 June 1941, at the beginning of Operation Barbarossa, some 981 were in service with the Soviet Air Forces (VVS), the Soviet Air Defence Forces (PVO) and Soviet Naval Aviation. The MiG-3 was difficult to fly in peacetime and much more so in combat. Originally designed as a high-altitude fighter-interceptor, combat over the Eastern Front was generally at lower altitudes, where it was inferior to the German Messerschmitt Bf 109 as well as most of its Soviet contemporaries. It was also pre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Messerschmitt Bf 109
The Messerschmitt Bf 109 is a monoplane fighter aircraft that was designed and initially produced by the Nazi Germany, German aircraft manufacturer Messerschmitt#History, Bayerische Flugzeugwerke (BFW). Together with the Focke-Wulf Fw 190, the Bf 109 formed the backbone of the ''Luftwaffe's'' fighter force during the World War II. It was commonly called the Me 109 by Allied aircrew and some German aces/pilots, even though this was not the official model designation. The Bf 109 was designed by Willy Messerschmitt and Robert Lusser, who worked at BFW during the early to mid-1930s. It was conceived as an interceptor aircraft, interceptor. However, later models were developed to fulfill multiple tasks, serving as Escort fighter, bomber escort, fighter-bomber, day fighter, day-, night fighter, night-, all-weather fighter, ground-attack aircraft, and aerial reconnaissance aircraft.
