Lavochkin La-17
The Lavochkin La-17 was the first Soviet Union, Soviet unmanned aerial vehicle (UAV) to reach operational service. The first versions were developed in the early 1950s, and remained in service into the 1980s. Early development The La-17 was designed by the Lavochkin design bureau, with work beginning in 1950. Flight tests began in 1953, with prototype drones carried on a Tupolev Tu-4 four-engine bomber. La-17 production began in 1956. The La-17 was a jet drone of all-metal construction, with straight flight surfaces, and a jet engine carried in a nacelle under the fuselage. The initial variant, which was just known as the "La-17", was air-launched. and powered by a Bondaryuk RD-900 ramjet with 800 kgf (1,760 lbf) thrust. There was a "windmill" type electric generator in the nose, somewhat along the lines of the WW II-era Luftwaffe's Me 163 manned rocket interceptor to provide electric power. The La-17 was directed by radio control and simply "bellied in" to land, with t ... [...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 ...

Mikulin RD-9
The Tumansky RD-9 (initially designated Mikulin AM-5) was an early Soviet turbojet engine, not based on pre-existing German or British designs. The AM-5, developed by scaling down the AM-3, was available in 1952 and completed testing in 1953; it produced thrust without afterburner. AM-5 engine is notable for making possible the first mass-produced supersonic interceptor, the MiG-19, and the first Soviet all-weather area interceptor, the Yak-25. When Sergei Tumansky replaced Alexander Mikulin as the OKB-24's chief designer in 1956, the engine was renamed RD-9. The engine was later built under license in China as the WP-6. Variants and applications ;RD-9A: ;RD-9B: Used in the East German civilian jetliner project Baade 152 in 1958 and 1959, replaced when Pirna 014 engines became available. ;RD-9AK: Non-afterburning versions for the Yak-25 and Yak-26. ;RD-9AF-300: Afterburning version for the Yak-27 and Yak-28. ;RD-9AF2-300: Afterburning version for the Yak-27 and Yak-28. ;RD-9B ...

People's Liberation Army
The People's Liberation Army (PLA) is the principal military force of the People's Republic of China and the armed wing of the Chinese Communist Party (CCP). The PLA consists of five service branches: the Ground Force, Navy, Air Force, Rocket Force, and Strategic Support Force. It is under the leadership of the Central Military Commission (CMC) with its chairman as commander-in-chief. The PLA can trace its origins during the Republican Era to the left-wing units of the National Revolutionary Army (NRA) of the Kuomintang (KMT) when they broke away on 1 August 1927 in an uprising against the nationalist government as the Chinese Red Army before being reintegrated into the NRA as units of New Fourth Army and Eighth Route Army during the Second Sino-Japanese War. The two NRA communist units were reconstituted into the PLA on 10 October 1947. Today, the majority of military units around the country are assigned to one of five theater commands by geographical location. ...

Sokol Design Bureau
Sokol Aircraft Plant (russian: Авиастроительный завод «Сокол», Aviastroitelny zavod Sokol, Sokol Aircraft-Building Plant) is a manufacturer of MiG fighters, based in Nizhny Novgorod. It was founded in 1932 and is also known as "Aviation Plant Nr. 21", named after Sergo Ordzhonikidze. During 45 years of serial production the plant manufactured about 13,500 combat aircraft. The company is headquartered in Nizhny Novgorod.

MiG-21
The Mikoyan-Gurevich MiG-21 (russian: Микоян и Гуревич МиГ-21; NATO reporting name: Fishbed) is a supersonic jet fighter and interceptor aircraft, designed by the Mikoyan-Gurevich Design Bureau in the Soviet Union. Its nicknames include: "balalaika", because its planform resembles the stringed musical instrument of the same name; "''Ołówek''", Polish for "pencil", due to the shape of its fuselage, and "''Én Bạc''", meaning "silver swallow", in Vietnamese. Approximately 60 countries across four continents have flown the MiG-21, and it still serves many nations six decades after its maiden flight.

Radiation Monitoring
Radiation monitoring involves the measurement of radiation dose or radionuclide contamination for reasons related to the assessment or control of exposure to radiation or radioactive substances, and the interpretation of the results. Environmental monitoring Environmental monitoring is the measurement of external dose rates due to sources in the environment or of radionuclide concentrations in environmental media. Source monitoring Source monitoring is a specific term used in ionising radiation monitoring, and according to the IAEA, is the measurement of activity in radioactive material being released to the environment or of external dose rates due to sources within a facility or activity. In this context a source is anything that may cause radiation exposure — such as by emitting ionising radiation, or releasing radioactive substances. The phrase "standard source" is also used as a de facto term in the more specific context of being a calibration standard source in ionisin ...

Reconnaissance
In military operations, reconnaissance or scouting is the exploration of an area by military forces to obtain information about enemy forces, terrain, and other activities. Examples of reconnaissance include patrolling by troops (skirmishers, long-range reconnaissance patrol, U.S. Army Rangers, cavalry scouts, or military intelligence specialists), ships or submarines, crewed or uncrewed reconnaissance aircraft, satellites, or by setting up observation posts. Espionage is usually considered to be different from reconnaissance, as it is performed by non-uniformed personnel operating behind enemy lines. Often called recce (British, Canadian and Australian English) or recon (American English), the word for this activity has at its root the associated verb ''reconnoitre'' or ''reconnoiter''. Etymology The word from the Middle French ''reconoissance''. Overview Reconnaissance conducted by ground forces includes special reconnaissance, armored reconnaissance, amp ...
