Kharkiv KhAI-5
The Kharkiv KhAI-5, (sometimes Neman R-10) was a Soviet reconnaissance and light bomber aircraft, designed in the mid-1930s in the Kharkiv Aviation Institute (KhAI, - in Ukrainian: ХАІ), under the direction of Iosif Grigorevich Nyeman (sometimes written as Neman). Development The first prototype of the plane, with a factory designation KhAI-5 (ХАІ-5), flew in June 1936. Despite a lower performance, the aircraft won a contest against another reconnaissance plane design, the Kochyerigin R-9, and was accepted for a production with the military designation R-10 ('R' indicated ''razvyedchik'' meaning reconnaissance in Russian). It was a modern design for the time. 493 R-10s were manufactured in the Kharkiv and Saratov aviation plants by early 1940. The first series showed some teething problems, which resulted in Iosif Nyeman being arrested by the NKVD on December 11, 1938 under the accusation of sabotage and espionage, a common accusation at the time. In 1938 a variant, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kharkiv Aviation Institute
Kharkiv, also known as Kharkov, is the second-largest List of cities in Ukraine, city in Ukraine.Kharkiv "never had eastern-western conflicts" , ''Euronews'' (23 October 2014) Located in the northeast of the country, it is the largest city of the historic region of Sloboda Ukraine. Kharkiv is the administrative centre of Kharkiv Oblast and Kharkiv Raion. Prior to the Russian invasion of Ukraine in early 2022, it had an estimated population of 1,421,125. Founded in 1654 as a Cossacks, Cossack fortress, by late 19th century Kharkiv had developed within the Russian Empire as a major commercial and industrial centre. From December 1919 to January 1934, Kharkiv was the capital of the Ukrainian Soviet Socialist Rep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bomb
A bomb is an explosive weapon that uses the exothermic reaction of an explosive material to provide an extremely sudden and violent release of energy. Detonations inflict damage principally through ground- and atmosphere-transmitted mechanical stress, the impact and penetration of pressure-driven projectiles, pressure damage, and explosion-generated effects. Bombs have been utilized since the 11th century starting in East Asia. The term ''bomb'' is not usually applied to explosive devices used for civilian purposes such as construction or mining, although the people using the devices may sometimes refer to them as a "bomb". The military use of the term "bomb", or more specifically aerial bomb action, typically refers to airdropped, unpowered explosive weapons most commonly used by air forces and naval aviation. Other military explosive weapons not classified as "bombs" include shells, depth charges (used in water), or land mines. In unconventional warfare, other names ...

Bomb Bay
The bomb bay or weapons bay on some military aircraft is a compartment to carry bombs, usually in the aircraft's fuselage, with "bomb bay doors" which open at the bottom. The bomb bay doors are opened and the bombs are dropped when over the target or at a specified launching point. History and function Bomb bays were born of necessity. Early military aircraft suffered severe aerodynamic drag (which would further slow down the already lumbering bomb-laden aircraft) with bombs hanging from the wings or below the fuselage, so military aviation designers moved the bombs inside the aircraft. Before the introduction of stealth technology bomb bays were mostly used by dedicated bomber aircraft; in fighters and attack airplanes bombs and rockets were hung from the wings or fuselage on hardpoint#Pylon, pylons. Notable exceptions are the F-101, F-102 and F-106 interceptor aircraft, all of which had bays used to store missiles, or other weapons stores. Today many designers have moved ...

Camera
A camera is an instrument used to capture and store images and videos, either digitally via an electronic image sensor, or chemically via a light-sensitive material such as photographic film. As a pivotal technology in the fields of photography and videography, cameras have played a significant role in the progression of visual arts, media, entertainment, surveillance, and scientific research. The invention of the camera dates back to the 19th century and has since evolved with advancements in technology, leading to a vast array of types and models in the 21st century. Cameras function through a combination of multiple mechanical components and principles. These include exposure control, which regulates the amount of light reaching the sensor or film; the lens, which focuses the light; the viewfinder, which allows the user to preview the scene; and the film or sensor, which captures the image. Several types of camera exist, each suited to specific uses and offering unique cap ... [...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.

Semi-monocoque
The term semi-monocoque or semimonocoque refers to a stressed shell structure that is similar to a true monocoque, but which derives at least some of its strength from conventional reinforcement. Semi-monocoque construction is used for, among other things, aircraft fuselages, car bodies and motorcycle frames. Examples of semi-monocoque vehicles Semi-monocoque aircraft fuselages differ from true monocoque construction through being reinforced with longitudinal stringers. The Mooney Aviation Company, Mooney range of four seat aircraft, for instance, use a steel tube truss frame around the passenger compartment with monocoque behind. The British ARV Super2 light aircraft has a fuselage constructed mainly of aluminium alloy, but with some fibreglass elements. The cockpit is a stiff monocoque of "Supral" alloy, but aft of the cockpit bulkhead, the ARV is conventionally built, with frames, longerons and stressed skin forming a semi-monocoque."Pilot" magazine, June 1985 pages 5-6 ...

Winter War
The Winter War was a war between the Soviet Union and Finland. It began with a Soviet invasion of Finland on 30 November 1939, three months after the outbreak of World War II, and ended three and a half months later with the Moscow Peace Treaty on 13 March 1940. Despite superior military strength, especially in tanks and aircraft, the Soviet Union suffered severe losses and initially made little headway. The League of Nations deemed the attack illegal and expelled the Soviet Union from its organization. The Soviets made several demands, including that Finland cede substantial border territories in exchange for land elsewhere, claiming security reasonsprimarily the protection of Leningrad, from the Finnish border. When Finland refused, the Soviets invaded. Most sources conclude that the Soviet Union had intended to conquer all of Finland, and cite the establishment of the Finnish Democratic Republic, puppet Finnish Communist government and the Molotov–Ribbentrop Pact' ...

Battle Of Khalkhin Gol
The Battles of Khalkhin Gol (; ) were the decisive engagements of the undeclared Soviet–Japanese border conflicts involving the Soviet Union, Mongolia, Japan and Manchukuo in 1939. The conflict was named after the river Khalkhin Gol, which passes through the battlefield. In Japan, the decisive battle of the conflict is known as the after Nomonhan Burd Obo, an ''obo'', a cairn set as a border marker in the Yongzheng period of the Qing dynasty. The battles resulted in the defeat of the Japanese Sixth Army. Background After the Japanese occupation of Manchuria in 1931, Japan turned its military interests to Soviet territories that bordered those areas. Meanwhile, the Soviet Union and the People's Republic of Mongolia signed an Mutual Assistance Pact in March 1936, allowing the former to send troops to Mongolia. In the same year, Japan signed the Anti-Comintern Pact in response. Following Japan's full invasion of China in July 1937, the Soviet Union sent the 57th Special ...
