RSA (missile)
The RSA is one of the earliest surface-to-air missiles systems, developed by the Swiss companies Oerlikon-Bührle and Contraves starting in 1947. The missile went through a rapid development process with several upgraded versions, and was the first anti-aircraft missile offered for commercial sale when it was placed on the market in the RSC-50 form. The US tested 25 of the slightly different RSC-51 model under the name MX-1868. No further sales were forthcoming. Several improved versions followed, including the RSC-54, RSC-56, RSC-57 and RSC/RSD-58. These saw small numbers of sales, mostly as training rounds. History Background Oerlikon had been a leader in the development of anti-aircraft weapons after its purchase of the SEMAG company in 1924, and the subsequent takeover by Emil Georg Bührle the next year. Their most famous products were the variety of Oerlikon 20 mm cannon that started at SEMAG and underwent considerable further development prior to the opening of World War II. ...

Oerlikon-Bührle
''Oerlikon-Bührle'' (full name ''Werkzeugmaschinenfabrik Oerlikon, Bührle & Co.'', initially ''Werkzeugmaschinenfabrik Oerlikon'') was a Swiss armaments company based in Oerlikon (Zürich) from 1906 to 1999.Jürg Fink: ''Switzerland as seen by the Third Reich, 1933-1945.'' 1985, page 145. After restructurings and the sale of various core divisions, in particular the armaments division Oerlikon Contraves Defence to the German Rheinmetall DeTec, the holding company was merged into the present OC Oerlikon in January 2000. Short review from the book by Daniel Heller History 20-mm-Oerlikon anti-aircraft gun in use by the US Navy on USS Enterprise (CV-6) (May 1943) Founded in 1906, the ''Schweizerische Werkzeugmaschinenfabrik Oerlikon'' (SWO), a spin-off of the Maschinenfabrik Oerlikon, had been taken over by the ''Magdeburger Werkzeugmaschinenfabrik'' in 1923, thus saving it from bankruptcy.

Flieger-Flab-Museum
The Flieger Flab Museum (English: Swiss Air Force Museum) is located in the Canton of Zurich in Dübendorf on the grounds of Dübendorf Air Base. In the museum, 40 airplanes and helicopters are displayed, with the collection divided into distinct eras: pioneers and World War I, the 1930s, World War II and the postwar period, the beginning of the jet age, the development of jet fighters, the Cold War, and arms reduction. History The collection was founded in 1972 by the Office for Military Airfields and dedicated to the history of Swiss military aviation and air defense. In 1972–1978, the collection was turned over to the state by the Swiss Federal Office for military airfields. In 1978, for the first time, the public were able to contribute to the collection, which grew steadily over the next few years. Finally, in 1979, the Friends of the Museum of the Swiss air force (VFMF) was formed, initiated by Hans Giger, the Director of the Federal Office for military airfields. Dur ...

RSD 58
The RSD 58 is an early production surface-to-air missile system developed by Contraves-Oerlikon in Switzerland from 1947.David A. AndertonSwiss Build Mobile Anti-Aircraft Missile ''Aviation Week'', June 30, 1958. Test firings were made in Switzerland and Italy in 1958, and Japan placed a small order for training purposes, but the missile was not produced in high numbers. The missile system was developed from the earlier RSA Missile developed by the same companies. Design and development Contraves-Oerlikon started design work on guided missiles to supplement their anti-aircraft guns, like the popular 20 mm cannon, in 1947. The company produced a number of designs, including the RSA, culminating in the RSD 58 of 1958. The RSD 58 was a liquid-fuelled rocket-powered missile, guided to its target by riding a radar beam. The missile body was made of wrapped tubing and sheet with Araldite bonding while the wings were of sandwich construction. Targeting was by search radar and beam tr ...

Beam Riding
Beam-riding, also known as Line-Of-Sight Beam Riding (LOSBR) or beam guidance, is a technique of directing a missile to its target by means of radar or a laser beam. The name refers to the way the missile flies down the guidance beam, which is aimed at the target. It is one of the simplest guidance systems and was widely used on early missile systems, however it had a number of disadvantages and is now found typically only in short-range roles. Basic concept Beam riding is based on a signal that is pointed towards the target. The signal does not have to be powerful, as it is not necessary to use it for tracking as well. The main use of this kind of system is to destroy airplanes or tanks. First, an aiming station (possibly mounted on a vehicle) in the launching area directs a narrow radar or laser beam at the enemy aircraft or tank. Then, the missile is launched and at some point after launch is “gathered” by the radar or laser beam when it flies into it. From this stage onwa ...

Brown, Boveri & Cie
Brown, Boveri & Cie. (Brown, Boveri & Company; BBC) was a Swiss group of electrical engineering companies. It was founded in Zürich, in 1891 by Charles Eugene Lancelot Brown and Walter Boveri who worked at the Maschinenfabrik Oerlikon. In 1970 BBC took over the Maschinenfabrik Oerlikon. In 1988 it merged with ASEA to form ABB. Early History of BBC Brown Boveri BBC Brown Boveri was established in 1891. The company was one of only a few multinational corporations to operate subsidiaries that were larger than the parent company. Because of the limitations of the Swiss domestic market, Brown Boveri established subsidiaries throughout Europe relatively early in its history, and at times had difficulty maintaining managerial control over some of its larger operating units. The merger with ASEA, a company which was praised for its strong management, was expected to help Brown Boveri reorganize and reassert control over its vast international network. Activity in Britain Brown Bove ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Concorde
The Aérospatiale/BAC Concorde () is a retired Franco-British supersonic airliner jointly developed and manufactured by Sud Aviation (later Aérospatiale) and the British Aircraft Corporation (BAC). Studies started in 1954, and France and the UK signed a treaty establishing the development project on 29 November 1962, as the programme cost was estimated at £70 million (£ in ). Construction of the six prototypes began in February 1965, and the first flight took off from Toulouse on 2 March 1969. The market was predicted for 350 aircraft, and the manufacturers received up to 100 option orders from many major airlines. On 9 October 1975, it received its French Certificate of Airworthiness, and from the UK CAA on 5 December. Concorde is a tailless aircraft design with a narrow fuselage permitting a 4-abreast seating for 92 to 128 passengers, an ogival delta wing and a droop nose for landing visibility. It is powered by four Rolls-Royce/Snecma Olympus 593 turbo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fineness Ratio
In naval architecture and aerospace engineering, the fineness ratio is the ratio of the length of a body to its maximum width. Shapes that are short and wide have a low fineness ratio, those that are long and narrow have high fineness ratios. Aircraft that spend time at supersonic speeds, e.g. the Concorde, generally have high fineness ratios. At speeds below critical mach, one of the primary forms of drag is skin friction. As the name implies, this is drag caused by the interaction of the airflow with the aircraft's skin. To minimize this drag, the aircraft should be designed to minimize the exposed skin area, or "wetted surface". One solution to this problem is constructing an "egg shaped" fuselage, for example as used on the home-built Questair Venture. Theoretical ideal fineness ratios in subsonic aircraft fuselages are typically found at about 6:1, however this may be compromised by other design considerations such as seating or freight size requirements.

Holloman Air Force Base
Holloman Air Force Base is a United States Air Force base established in 1942 located six miles (10 km) southwest of the central business district of Alamogordo, and a census-designated place in Otero County, New Mexico, United States. The base was named in honor of Col. George V. Holloman, a pioneer in guided missile research. It is the home of the 49th Wing (49 WG) of the Air Education and Training Command (AETC). In addition to hosting several combat wings, Holloman supports the nearby White Sands Missile Range and currently hosts the Royal Air Force RPAS (Remotely Piloted Aircraft System) Formal Training Unit (FTU) and the Italian Air Force RPA training courses. The base previously hosted the German Air Force Flying Training Center. History Planned for the British Overseas Training program which they did not pursue, construction for the USAAF base west of Alamogordo, New Mexico, began on 6 February 1942. After the nearby Alamogordo Bombing and Gunnery Range was e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
