Wassmer WA-26 Squale
The Wassmer WA 26 Squale ( en, Shark) is a single seat, 15 m (49 ft 3 in) span competition glider, designed and produced in France in the late 1960s. It has wooden wings and a glass fibre fuselage. The Wassmer WA 28 Espadon ( en, Swordfish) is an aerodynamically very similar development with a glass fibre wing. Design and development From 1956 until at least 1964 Wassmer built and developed the successful Javelot series of single seat gliders. These had wooden wings with NACA laminar flow profiles and steel framed fuselages, covered entirely with fabric on early models but later with a mixture of fabric and glass fiber. The Squale was attempt to break into the high performance market. Like the Javelots, it had a wooden wing but one with a Wortmann profile; its fuselage was a more aerodynamically refined and wholly GRP structure. The straight edged high wing of the Squale has a slightly tapered centre section of about 60% of the span and more strong ...

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 Wikimedia project, 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 Magazine, 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 organization ...

Trailing Edge
The trailing edge of an aerodynamic surface such as a wing is its rear edge, where the airflow separated by the leading edge meets.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 521. Aviation Supplies & Academics, 1997. Essential flight control surfaces are attached here to control the direction of the departing air flow, and exert a controlling force on the aircraft. Such control surfaces include ailerons on the wings for roll control, elevators on the tailplane controlling pitch, and the rudder A rudder is a primary control surface used to steer a ship, boat, submarine, hovercraft, aircraft, or other vehicle that moves through a fluid medium (generally air or water). On an aircraft the rudder is used primarily to counter adve ... on the fin controlling yaw. Elevators and ailerons may be combined as elevons on tailless aircraft. The shape of the trailing edge is of prime importance in the aerodynamic function of any aerodynamic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glider Aircraft
A glider is a fixed-wing aircraft that is supported in flight by the dynamic reaction of the air against its lifting surfaces, and whose gliding flight, free flight does not depend on an engine. Most gliders do not have an engine, although motor-gliders have small engines for extending their flight when necessary by sustaining the altitude (normally a sailplane relies on rising air to maintain altitude) with some being powerful enough to take off by Motor glider, self-launch. There are a wide variety of types differing in the construction of their wings, aerodynamic efficiency, location of the pilot, controls and intended purpose. Most exploit lift (soaring), meteorological phenomena to maintain or gain height. Gliders are principally used for the air sports of gliding, hang gliding and paragliding. However some spacecraft have been designed to descend as gliders and in the past military gliders have been used in warfare. Some simple and familiar types of glider are toys such a ...

Wassmer Aircraft
Wassmer was a French specialized woodworking company formed by Bernard Wassmer in 1905. It later became an aircraft manufacturer specializing in Glider (sailplane), gliders. It was bought out by Issoire Aviation, a subsidiary of Siren, in 1978. Aircraft production The company entered into aircraft production in 1955 when it produced under licence a batch of Jodel D.112 two-seater aircraft at its factory at Issoire. The company also produced the single-seat WA-20 and two-seat WA-30 gliders. In 1959 the company produced the Wassmer WA-40, WA-40 Super IV a four-seat touring aircraft. In 1972 in co-operation with Siren they formed a joint company Consortium Europeén de Réalisation et de Ventes d'Avions (CERVA) to build a metal variant of the WA4/21, itself a variant of the WA-40. The components for the Cerva CE.43 Guépard were manufactured by Siren at Argenton-sur-Creuse and final assembly, equipment fitting and flight testing was carried out by Wassmer at Issoire. The company also ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
