Lavochkin La-130
The Lavochkin La-9 (NATO reporting name Fritz) was a Soviet fighter aircraft produced shortly after World War II. It was one of the last piston engined fighters to be produced before the widespread adoption of the jet engine. Development La-9 represents a further development of the Lavochkin La-126 prototype. The first prototype, designated La-130 was finished in 1946. Similarity to the famous Lavochkin La-7 was only superficial – the new fighter had an all-metal construction and a laminar flow wing. Weight savings due to elimination of wood from the airframe allowed for greatly improved fuel capacity and four-cannon armament. Mock combat demonstrated that the La-130 was evenly matched with the La-7 but was inferior to the Yakovlev Yak-3 in horizontal planes. The new fighter, officially designated La-9, entered production in August 1946. A total of 1,559 aircraft were built by the end of production in 1948. Variants Like other aircraft designers at the time, Lavochkin was expe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...

Jet Propulsion
Jet propulsion is the propulsion of an object in one direction, produced by ejecting a jet of fluid in the opposite direction. By Newton's third law, the moving body is propelled in the opposite direction to the jet. Reaction engines operating on the principle of jet propulsion include the jet engine used for aircraft propulsion, the pump-jet used for marine propulsion, and the rocket engine and plasma thruster used for spacecraft propulsion. Physics Jet propulsion is produced by some reaction engines or animals when thrust is generated by a fast moving jet of fluid in accordance with Newton's laws of motion. It is most effective when the Reynolds number is high—that is, the object being propelled is relatively large and passing through a low-viscosity medium. In animals, the most efficient jets are pulsed, rather than continuous, at least when the Reynolds number is greater than 6. Specific impulse Specific impulse (usually abbreviated ''I''sp) is a measure of how effe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Victorious War Museum
The Victorious War Museum, or the Victorious Fatherland Liberation War Museum, is a history/military museum dedicated to the Korean War located in the North Korean capital-city of Pyongyang. The museum was first set up in August 1953 and built in the Central District of Pyongyang, initially named as the "Fatherland Liberation War Museum." In April 1963, it was relocated to the Sosong District and re-established in a purpose-built building compound. In 2014, the museum was renovated and upgraded significantly and the new design included a building spanning across the nearby Botong River, together with a large panorama-style display hall at the top. The general character and influence of the museum reflects the official North Korean view of their success in fighting against their American arch-enemy and its puppet state of South Korea, and much of the museum presents the victories of North Korea and its military over its enemies, which are shown to be utterly defeated and broken b ...

People's Liberation Army Air Force
The People's Liberation Army Air Force (PLAAF; ), also known as the Chinese Air Force (中国空军) or the People's Air Force (人民空军), is an aerial service branch of the People's Liberation Army, the regular armed forces of the People's Republic of China. The PLAAF was officially established on 11 November 1949 and it is composed of 5 branches which are aviation, anti-aircraft artillery, surface-to-air missiles (SAM), radar, and Airborne Corps.

V-1 Flying Bomb
The V-1 flying bomb (german: Vergeltungswaffe 1 "Vengeance Weapon 1") was an early cruise missile. Its official Ministry of Aviation (Nazi Germany), Reich Aviation Ministry () designation was Fi 103. It was also known to the Allies as the buzz bomb or doodlebug and in Germany as (cherry stone) or (maybug). The V-1 was the first of the (V-weapons) deployed for the terror bombing of London. It was developed at Peenemünde Army Research Center in 1939 by the at the beginning of the Second World War, and during initial development was known by the codename "Cherry Stone". Because of its limited range, the thousands of V-1 missiles launched into England were fired from V-1 flying bomb facilities, launch facilities along the French (Pas-de-Calais) and Dutch coasts. The Wehrmacht first launched the V-1s against London on 13 June 1944, one week after (and prompted by) the successful Operation Overlord, Allied landings in France.
