Fouga CM
Fouga (also known as Air Fouga) was a French manufacturing company established by Gaston Fouga at Béziers during 1920. Originally specialising in the repair of railway rolling stock, the firm eventually became most noted for the aircraft it produced from its woodworking facilities at Aire-sur-l'Adour. The most successful product to be created by Fouga was the CM.170 Magister, a postwar jet-powered military trainer aircraft derived from the firm's experiences with sailplanes. Many of its features, such as its slender tapering wings, reflecting the company's sailplane heritage. During May 1958, Fouga was acquired by rival French aircraft manufacturer Potez; the company's former facilities at Toulouse continue to produce aircraft as a part of the multinational Airbus Group. History During 1920, the company was established by Gaston Fouga; from the onset, it was based at the town of Béziers in the Occitanie region of Southern France. Initially, Fouga's operated centred aro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lublin R-XIII
The Lublin R-XIII was the Polish army cooperation plane (observation and liaison plane), designed in the early-1930s in the Plage i Laśkiewicz factory in Lublin. It was the main army cooperation plane in the Invasion of Poland. Its variant Lublin R-XIV was a military trainer aircraft. Design and development In 1927, the Polish aviation authorities announced a contest for an army-cooperation plane (in Polish: ''samolot towarzyszący'', literally: "accompanying plane"). In Polish doctrine it was a close reconnaissance, observation and liaison aircraft, operating from casual airfields, providing big Army land units with information about the enemy. The PZL state factory proposed the PZL Ł-2, built in a series of 25 aircraft, while private factory Plage i Laśkiewicz in Lublin proposed the Lublin R-X, designed by Jerzy Rudlicki. It was flown on February 1, 1929. Five aircraft were built for the Air Force as R-Xa, and one was built as a long-distance sports plane. The third competit ...

Tumansky R-13
The Tumansky R-13 is a Soviet turbojet engine designed by Sergei Alekseevich Gavrilov. Design and development The Tumansky R-13 is a development of the successful Tumansky R-11 engine. It is a two-spool axial-flow turbojet featuring a new five-stage high-pressure compressor, new combustion chamber design to facilitate restarting the engine at high altitudes, new afterburner, and greater use of titanium components. It is used by MiG-21M, MF, SM, and SMT, and Sukhoi Su-15M and TM. R-13 is also built in China as LM WP13, and experienced similar fate like Tumansky R-11: originally, both were licensed to be built in China, but after the Sino-Soviet split all Soviet technical support was withdrawn and Chinese proceeded on their own. Under the leadership of the general designer Jiang Hepu (江和甫), both R-11 and R-13 were successfully built in China. The R-95 is a non-afterburning development of this engine used by initial versions of the Sukhoi Su-25 The Sukhoi Su-25 ''Grach' ...

R-13 Regional Road (Montenegro)
R-13 regional road ( cnr, Regionalni put R-13) is a Montenegrin roadway. Section from Bioče to Mateševo is a parallel road to section of Bar–Boljare motorway that was finished in 2022. When this section of Bar–Boljare motorway was finished, R-13 regional road section from Mateševo to Kolašin would serve as a major connection from motorway to the highway. History The M-9 highway was officially opened for traffic in 1984. It was built as part of the larger M-9 highway within the Yugoslav highway network, spanning Montenegro, Kosovo and Serbia. It connected Kolašin and Andrijevica with Peć and Priština in Kosovo, and Leskovac and Pirot in Serbia. The M-9 highway originally flowed through the city of Kolašin to connect it to the M-2 highway. A bypass was built via the Vladoš Bridge to merge the M-9 with the M-2. On 27 March 2014, the Ministry of Transport and Maritime Affairs officially realigned the M-9 highway to its current alignment, incorporating the Vlado ...

R13 (drug)
R13 is a small-molecule flavonoid and orally active, potent, and selective agonist of the tropomyosin receptor kinase B (TrkB) – the main signaling receptor for the neurotrophin brain-derived neurotrophic factor (BDNF) – which is under development for the potential treatment of Alzheimer's disease. It is a structural modification and prodrug of tropoflavin (7,8-DHF) with improved potency and pharmacokinetics, namely oral bioavailability and duration. The compound is a replacement for the earlier tropoflavin prodrug R7 and has similar properties to it. It was developed because while R7 displayed a good drug profile in animal studies, it showed almost no conversion into tropoflavin in human liver microsomes. In contrast to R7, R13 is readily hydrolyzed into tropoflavin in human liver microsomes.

R-13 (missile)
The R-13 (russian: ракета-13) was a submarine-launched ballistic missile (SLBM) developed by the Soviet Union starting around 1955. It was assigned the NATO reporting name SS-N-4 Sark and carried the GRAU index 4K50. History Development of the R-13 was authorised by the Soviet Supreme Council on 25 July 1955 for use on the Project 629 and Project 658 submarines. The design work was started by OKB-1 under Sergei Korolev before being transferred to CB Miasskoe engineering / Makeyev Rocket Design Bureau (chief designer - Viktor Makeyev). Final technical specifications was approved by 11 January 1956. Serial production was undertaken at Zlatoust Machine-Building Plant in 1959. The R-13 was a single-stage liquid-fuel rocket and entered service in 1961. This missile was somewhat similar in design to the R-11FM missile, which caused some confusion in Western intelligence services during the Cold War. The missiles were phased out from 1965 to 1975. This missile was the firs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
R13 (Rodalies De Catalunya)
Rodalies de Catalunya (, ; "Commuter Rail of Catalonia") is the main commuter and regional rail system in the Spanish autonomous community of Catalonia. It is administered by the Government of Catalonia and operated by the national rail operator Renfe Operadora. The system consists of 17 service lines chiefly centered in the Barcelona area, serving a total of 203 stations throughout Catalonia, with an average number of 1,000 trains running on it every day. In 2016, it had an annual ridership of 117 million. Most part of the system is the precursor of several commuter and regional lines running on the Iberian gauge mainline network in Catalonia, which were formerly under the administration of the Spanish government. On , as a result of the transfer of the administration of the Cercanías commuter rail system for Barcelona, known in Catalan as Rodalies Barcelona, the system was renamed "Rodalies de Catalunya". One year later, Renfe's regional rail services within Catalonia w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chlorotrifluoromethane
Chlorotrifluoromethane, R-13, CFC-13, or Freon 13, is a non-flammable, non-corrosive chlorofluorocarbon (CFC) and also a mixed halomethane. It is a man-made substance used primarily as a refrigerant. When released into the environment, CFC-13 has a high ozone depletion potential, high global warming potential, and long atmospheric lifetime. Preparation It can be prepared by reacting carbon tetrachloride with hydrogen fluoride in the presence of a catalytic amount of antimony pentachloride: CCl4 + 3HF → CClF3 + 3HCl This reaction can also produce trichlorofluoromethane (CCl3F), dichlorodifluoromethane (CCl2F2) and tetrafluoromethane (CF4). Production phaseout Per the international Montreal Protocol, CFC-13 began a phase out and replacement with alternative substances starting in the early 1990s that will culminate in a global ban on its production. The atmospheric abundance of CFC-13 rose from 3.0 parts per trillion (ppt) in year 2010 to 3.3 ppt in year 2020 based ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
