Yakovlev Yak-17
The Yakovlev Yak-17 (russian: Яковлев Як-17; USAF/ DOD designation Type 16, NATO reporting name Feather) was an early Soviet jet fighter. It was developed from the Yak-15, the primary difference being tricycle landing gear. The trainer version, known as the Yak-17UTI (NATO reporting name Magnet), was the only Soviet jet trainer of the 1940s. Both aircraft were exported in small numbers and the Yak-17 was soon replaced by the far superior Mikoyan-Gurevich MiG-15 beginning in 1950. Design and development After the state acceptance trials of the Yak-15 in May 1947 recommended that the aircraft be modified with a tricycle landing gear more suitable for jet-powered aircraft, the Yakovlev design bureau began design of the Yak-15U or Yak-15U-RD-10 (''uloochshenny'' - improved). The main gear had to be redesigned to place the wheels behind the aircraft's center of gravity. The main gear was moved behind the front spar, and when retracted filled most of the space between the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jet Engine
A jet engine is a type of reaction engine discharging a fast-moving jet of heated gas (usually air) that generates thrust by jet propulsion. While this broad definition can include rocket, Pump-jet, water jet, and hybrid propulsion, the term typically refers to an internal combustion airbreathing jet engine such as a turbojet, turbofan, ramjet, or pulse jet engine, pulse jet. In general, jet engines are internal combustion engines. Airbreathing jet engines typically feature a Axial compressor, rotating air compressor powered by a turbine, with the leftover power providing thrust through the propelling nozzle—this process is known as the Brayton cycle, Brayton thermodynamic cycle. Jet aircraft use such engines for long-distance travel. Early jet aircraft used turbojet engines that were relatively inefficient for subsonic flight. Most modern subsonic jet aircraft use more complex High-bypass turbofan, high-bypass turbofan engines. They give higher speed and greater fuel eff ...

Prague
Prague ( ; cs, Praha ; german: Prag, ; la, Praga) is the capital and largest city in the Czech Republic, and the historical capital of Bohemia. On the Vltava river, Prague is home to about 1.3 million people. The city has a temperate oceanic climate, with relatively warm summers and chilly winters. Prague is a political, cultural, and economic hub of central Europe, with a rich history and Romanesque, Gothic, Renaissance and Baroque architectures. It was the capital of the Kingdom of Bohemia and residence of several Holy Roman Emperors, most notably Charles IV (r. 1346–1378). It was an important city to the Habsburg monarchy and Austro-Hungarian Empire. The city played major roles in the Bohemian and the Protestant Reformations, the Thirty Years' War and in 20th-century history as the capital of Czechoslovakia between the World Wars and the post-war Communist era. Prague is home to a number of well-known cultural attractions, many of which survived the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prague Aviation Museum, Kbely
Kbely Aviation Museum (''Letecké Muzeum Kbely'') is the largest aviation museum in the Czech Republic and one of the largest of its kind in Europe. It is located to the north-east of Prague, at the military airport Kbely. Creation of the museum During the mid-1960s, the Prague Military Museum commenced a programme to recover, restore and preserve historic aircraft from around the country for eventual display at Kbely. Initially, one hangar was used, and about fifty aircraft were placed on public display. The aircraft collection continued to grow, and one of the original Wagner-type hangars on the airfield was brought into use, and now contains the earliest aircraft types on display. Another Picha-type hangar has also been added to bring the number of hangars housing the large and varied collection to four. The aircraft collection The collection at Kbely now includes 275 aircraft, of which approximately 110 are on public display at any given time. The museum contains many Czech d ...

Monino
Monino (russian: Мо́нино) is an urban locality (a work settlement) in Shchyolkovsky District of Moscow Oblast, Russia, located east of Moscow. Population: History Monino was founded in the Muninskaya Wasteland (russian: Мунинская пустошь) on August 23, 1792. The name "Monino" or "Munin" can be translated from the Finno-Ugric languages as "My farm". It is alleged that the history of the settlement can be traced to a small farm, whose owner was a man of Monin. In 1926, an airfield for heavy aircraft was built, becoming the first to house a heavy bomber brigade. The subsequent history of the village is closely connected with aviation. The status of urban-type settlement was conferred in 1946. Until 1965, it was part of the Noginsk District. Trivia The Central Air Force Museum in Monino is one of the world's largest aviation museums, and the largest for Russian aircraft. 173 aircraft and 127 aircraft engines are on display, and the museum als ...

Yakovlev 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 di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Junkers Jumo 004
The Junkers Jumo 004 was the world's first production turbojet engine in operational use, and the first successful axial compressor turbojet engine. Some 8,000 units were manufactured by Junkers in Germany late in World War II, powering the Messerschmitt Me 262 fighter and the Arado Ar 234 reconnaissance/bomber, along with prototypes, including the Horten Ho 229. Variants and copies of the engine were produced in Eastern Europe and the USSR for several years following the end of WWII. Design and development The feasibility of jet propulsion had been demonstrated in Germany in early 1937 by Hans von Ohain working with the Heinkel company. Most of the Reich Air Ministry ( RLM) remained uninterested, but Helmut Schelp and Hans Mauch saw the potential of the concept and encouraged Germany's aero engine manufacturers to begin their own programmes of jet engine development. The companies remained skeptical and little new development was carried out. In 1939 Schelp and Mauch visited th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Periscope
A periscope is an instrument for observation over, around or through an object, obstacle or condition that prevents direct line-of-sight observation from an observer's current position. In its simplest form, it consists of an outer case with mirrors at each end set parallel to each other at a 45° angle. This form of periscope, with the addition of two simple lenses, served for observation purposes in the trenches during World War I. Military personnel also use periscopes in some gun turrets and in armoured vehicles. More complex periscopes using prisms or advanced fiber optics instead of mirrors and providing magnification operate on submarines and in various fields of science. The overall design of the classical submarine periscope is very simple: two telescopes pointed into each other. If the two telescopes have different individual magnification, the difference between them causes an overall magnification or reduction. Early examples Johannes Hevelius described an early ...

Drop Tank
In aviation, a drop tank (external tank, wing tank or belly tank) is used to describe auxiliary fuel tanks externally carried by aircraft. A drop tank is expendable and often capable of being jettisoned. External tanks are commonplace on modern military aircraft and occasionally found in civilian ones, although the latter are less likely to be discarded except in an emergency. Overview The primary disadvantage with drop tanks is that they impose a drag penalty on the aircraft. External fuel tanks will also increase the moment of inertia, thereby reducing roll rates for air maneuvers. Some of the drop tank's fuel is used to overcome the added drag and weight of the tank. Drag in this sense varies with the square of the aircraft's speed. The use of drop tanks also reduces the number of external hardpoints available for weapons, reduces the weapon-carrying capacity and increases the aircraft's radar signature. Usually the fuel in the drop tanks is consumed first, and only when a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
