Stampe Et Vertongen SV.7
The Stampe et Vertongen SV.5 Tornado was a military trainer aircraft designed and built in Belgium in the 1930s.Taylor 1989, p.839''The Illustrated Encyclopedia of Aircraft'', p.2955 It saw service with the Belgian Air ForceJouhaud 1999, p.85 and Latvian Air Force,Jouhaud 1999, p.84 and Latvian firm VEF purchased a production license, although it is uncertain whether it built any examples. Design and development The SV.5 was Stampe et Vertongen's response to a 1933 requirement by the Belgian Air Force for a two-seat training biplane with aerobatic capabilities. Jean Stampe directed designer George Ivanow to update the company's RSV.22 to meet the new specifications, but the resulting design was an entirely new aircraft with only a superficial resemblance to its predecessor. It was a conventional, single-bay biplane with staggered wings of unequal span.Jouhaud 1999, p.87 The pilot and instructor sat in open cockpits in tandem and the aircraft was powered by an Armstrong Siddel ...

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 ...

Biplanes
A biplane is a fixed-wing aircraft with two main wings stacked one above the other. The first powered, controlled aeroplane to fly, the Wright Flyer, used a biplane wing arrangement, as did many aircraft in the early years of aviation. While a biplane wing structure has a structural advantage over a monoplane, it produces more drag than a monoplane wing. Improved structural techniques, better materials and higher speeds made the biplane configuration obsolete for most purposes by the late 1930s. Biplanes offer several advantages over conventional cantilever monoplane designs: they permit lighter wing structures, low wing loading and smaller span for a given wing area. However, interference between the airflow over each wing increases drag substantially, and biplanes generally need extensive bracing, which causes additional drag. Biplanes are distinguished from tandem wing arrangements, where the wings are placed forward and aft, instead of above and below. The term is also o ...

1930s Belgian Military Trainer Aircraft
Year 193 ( CXCIII) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Sosius and Ericius (or, less frequently, year 946 '' Ab urbe condita''). The denomination 193 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Air Enthusiast
''Air Enthusiast'' was a British, bi-monthly, aviation magazine, published by the Key Publishing group. Initially begun in 1974 as ''Air Enthusiast Quarterly'', the magazine was conceived as a historical adjunct to '' Air International'' magazine. ''Air International'' was (and still is) involved with current aviation topics and the ''Quarterly'' concerned itself with historical matters. Each issue contained 80 pages; as a result certain articles were divided and each part appeared over a number of issues. ''Air Enthusiast'' was illustrated with colour and black-and-white photos, diagrams, profiles and three-view drawings. Earlier issues featured cutaway drawings, but these were dropped. The articles provided detail for varieties of aircraft An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from ...

Pratt & Whitney Wasp Junior
The Pratt & Whitney R-985 Wasp Junior is a series of nine-cylinder, air-cooled, radial aircraft engines built by the Pratt & Whitney Aircraft Company from the 1930s to the 1950s. These engines have a displacement of ; initial versions produced , while the most widely used versions produce . Wasp Juniors have powered numerous smaller civil and military aircraft, including small transports, utility aircraft, trainers, agricultural aircraft, and helicopters. Over 39,000 engines were built, and many are still in service today. Design and development Pratt & Whitney developed the R-985 Wasp Junior as a smaller version of the R-1340 Wasp to compete in the market for medium-sized aircraft engines. Like its larger brother, the Wasp Junior was an air-cooled, nine-cylinder radial, with its power boosted by a gear-driven single-speed centrifugal type supercharger. Its cylinders were smaller, however, with a bore and stroke of , giving a 27% lesser total displacement. The Wasp Junior used ...

Armstrong Siddeley Cheetah
The Armstrong Siddeley Cheetah is a seven-cylinder British air-cooled aircraft radial engine of 834 cu in (13.65 L) capacity introduced in 1935 and produced until 1948. Early variants of the Cheetah were initially known as the Lynx Major.Lumsden 2003, p.74. The Cheetah was used to power many British trainer aircraft during World War II including the Avro Anson and Airspeed Oxford. Design and development The Cheetah was developed from the earlier Lynx using the increased bore cylinders from the Armstrong Siddeley Panther but the engine retained the stroke of the Lynx. Initially only direct-drive variants were produced with later engines being made available with propeller reduction gear of various ratios. Superchargers were also available for later variants, both geared and directly driven by the crankshaft. The basic design of the Cheetah remained unchanged from its introduction in 1935 to the last examples built in 1948. It was the first engine of its type to be certified ...

NACA Cowl
The NACA cowling is a type of aerodynamic fairing used to streamline radial engines installed on airplanes. It was developed by Fred Weick of the National Advisory Committee for Aeronautics (NACA) in 1927. It was a major advance in aerodynamic drag reduction, and paid for its development and installation costs many times over due to the gains in fuel efficiency that it enabled. History and design The NACA cowling enhanced speed through drag reduction while delivering improved engine cooling. The cowling consists of a symmetric, circular airfoil that is wrapped around the engine. In a normal planar airfoil, like a wing, it is the difference in airspeed, and their associated changes in pressure, on the top and bottom of the surface that produces lift. In the case of the NACA cowl, the ring-shaped airfoil is positioned so this lift effect is forward, producing thrust. This thrust does not counteract the total drag of the cowl, but greatly reduces its overall value. The differenc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caproni Ca
Caproni, also known as ''Società de Agostini e Caproni'' and ''Società Caproni e Comitti'', was an Italian aircraft manufacturer. Its main base of operations was at Taliedo, near Linate Airport, on the outskirts of Milan. Founded by Giovanni Battista "Gianni" Caproni during 1908, the company produced several successful heavy bombers during the First World War. Following the acquisition of several other aviation firms throughout the interwar period, Caproni transformed into a sizable aviation-orientated syndicate, the ''Società Italiana Caproni, Milano''. The majority of its aircraft were bombers and transport aircraft. It played a pioneering role in the development of the Caproni Campini N.1, an experimental aircraft powered by a thermo-jet. It provided large numbers of combat aircraft for the Axis during the Second World War. The firm did not prosper in the postwar era, the Società Italiana Caproni collapsing during 1950. Many of the company's former assets were subseque ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
