1-35 Armor
The Schweizer SGS 1-35 is a United States 15 Meter Class, single-seat, mid-wing glider built by Schweizer Aircraft of Elmira, New York.Said, Bob: ''1983 Sailplane Directory, Soaring Magazine'', page 33. Soaring Society of America, November 1983. USPS 499-920 The 1-35 was first flown in 1973 and a total of 101 were completed by the time production was completed in 1982. Background By the early 1970s competition in the open, standard and 15 meter classes was dominated by fiberglass sailplanes. Schweizer Aircraft evaluated the use of fiberglass for sailplane construction but rejected it for several reasons:Schweizer, Paul A: ''Wings Like Eagles, The Story of Soaring in the United States'', pages 159-209. Smithsonian Institution Press, 1988. *The high cost of demonstrating to the Federal Aviation Administration that this new material could safely be used for aircraft primary structure. *Problems with crash resistance of fiberglass structures in high-impact accidents. *The unknown s ...

Monocoque
Monocoque ( ), also called structural skin, is a structural system in which loads are supported by an object's external skin, in a manner similar to an egg shell. The word ''monocoque'' is a French term for "single shell". First used for boats, a true monocoque carries both tensile and compressive forces within the skin and can be recognised by the absence of a load-carrying internal frame. Few metal aircraft other than those with milled skins can strictly be regarded as pure monocoques, as they use a metal shell or sheeting reinforced with frames riveted to the skin, but most wooden aircraft are described as monocoques, even though they also incorporate frames. By contrast, a semi-monocoque is a hybrid combining a tensile stressed skin and a compressive structure made up of longerons and ribs or frames. Other semi-monocoques, not to be confused with true monocoques, include vehicle unibodies, which tend to be composites, and inflatable shells or balloon tanks, both of which ...

Schweizer Aircraft
The Schweizer Aircraft Corporation was an American manufacturer of sailplanes, agricultural aircraft and helicopters located in Horseheads, New York. It was incorporated in 1939 by three Schweizer brothers (Paul, William, and Ernest), who built their first glider, the Schweizer SGP 1-1, SGP 1-1, in 1930. Previously the oldest privately owned aircraft company in the United States, Schweizer was acquired by Sikorsky Aircraft Corporation of Stratford, Connecticut in 2004, and became a diversified aerospace company. Schweizer Aircraft ceased operations in 2012. It was sold to Schweizer R.S.G. in 2018 and production lines were opened again in Fort Worth, Texas. The company was producing three helicopter models in 2021. History The company grew out of the Mercury Glider Club which produced the first two Schweizer gliders in the Schweizers' barn. The company was originally called the Schweizer Metal Aircraft Company. Attorney Bob McDowell indicated to the Schweizers that they shoul ...

1970s United States Sailplanes
Year 197 ( CXCVII) was a common year starting on Saturday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Magius and Rufinus (or, less frequently, year 950 ''Ab urbe condita''). The denomination 197 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. Events By place Roman Empire * February 19 – Battle of Lugdunum: Emperor Septimius Severus defeats the self-proclaimed emperor Clodius Albinus at Lugdunum (modern Lyon). Albinus commits suicide; legionaries sack the town. * Septimius Severus returns to Rome and has about 30 of Albinus's supporters in the Senate executed. After his victory he declares himself the adopted son of the late Marcus Aurelius. * Septimius Severus forms new naval units, manning all the triremes in Italy with heavily armed troops for war in the East.

National Soaring Museum
The National Soaring Museum (NSM) is an aviation museum whose stated aim is to preserve the history of motorless flight. It is located on top of Harris Hill near Elmira, New York, United States. The NSM is the Soaring Society of America's official repository. In 1975, the SSA Board of Directors transferred the Soaring Hall of Fame to the National Soaring Museum. The museum features a large collection of vintage and historical gliders. The museum also administers the National Landmark of Soaring program to recognize people, places and events which are significant in the history of motorless aviation. History Elmira and Harris Hill have long been associated with soaring in the USA. The establishment of the nation's most prolific glider manufacturer, Schweizer Aircraft in Elmira and the holding of first 13 National Soaring Contests at the site between 1930 and 1946 guaranteed its stature as a location. During the US National Soaring Contests in the 1950s competitors and organizer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transport Canada
Transport Canada (french: Transports Canada) is the department within the Government of Canada responsible for developing regulations, policies and services of road, rail, marine and air transportation in Canada. It is part of the Transportation, Infrastructure and Communities (TIC) portfolio. The current Minister of Transport is Omar Alghabra. Transport Canada is headquartered in Ottawa, Ontario. History The Department of Transport was created in 1935 by the government of William Lyon Mackenzie King in recognition of the changing transportation environment in Canada at the time. It merged three departments: the former Department of Railways and Canals, the Department of Marine, and the Civil Aviation Branch of the Department of National Defence (c. 1927 when it replaced the Air Board) under C. D. Howe, who would use the portfolio to rationalize the governance and provision of all forms of transportation (air, water and land). He created a National Harbours Board and Trans-C ...

World Gliding Championships
The World Gliding Championships (WGC) is a gliding competition held every two years or so by the FAI Gliding Commission. The dates are not always exactly two years apart, often because the contests are sometimes held in the summer in the Southern Hemisphere. History Gliding had been a demonstration sport at the 1936 Summer Olympics and was due to become an official Olympic sport in the Helsinki Games in 1940. However, since the Second World War, gliding has not featured in the Olympics, and so the World Championships are the highest level in the sport. There are now contests for six classes of glider and so in recent years the Championships have been divided between two locations. The women's, junior, grand prix and aerobatic events are also held separately. Each of the following entries give the year and location of the contest followed by the winner of each class, nationality and the glider used. A list of future events is available here World Grand Prix Gliding Champ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Airfoil
An airfoil (American English) or aerofoil (British English) is the cross-sectional shape of an object whose motion through a gas is capable of generating significant lift, such as a wing, a sail, or the blades of propeller, rotor, or turbine. A solid body moving through a fluid produces an aerodynamic force. The component of this force perpendicular to the relative freestream velocity is called lift. The component parallel to the relative freestream velocity is called drag. An airfoil is a streamlined shape that is capable of generating significantly more lift than drag. Airfoils can be designed for use at different speeds by modifying their geometry: those for subsonic flight generally have a rounded leading edge, while those designed for supersonic flight tend to be slimmer with a sharp leading edge. All have a sharp trailing edge. Foils of similar function designed with water as the working fluid are called hydrofoils. The lift on an airfoil is primarily the result o ...

Glasflügel 303
The Glasflügel 303 Mosquito is a composite 15 metre Class single-seat sailplane manufactured by Glasflügel between 1976 and 1980. Design and development Designed for the 15 metre racing class, the Mosquito married the Standard Class Hornet fuselage with a flapped wing employing the then widely-used FX 67-K-170 airfoil developed at the University of Stuttgart by Professor Franz Wortmann. The Mosquito had a new design of one-piece canopy rather than the two-piece canopy used on the Hornet. This profile and its sister profile FX 67-K-150 are among the most prolific in the history of gliding, as they were employed also in the Nimbus-2, Mini-Nimbus, DG-200 and DG-400, PIK-20, Kestrel, Mosquito, Vega, Jantar and LAK-12 among other types. The 303 wing featured innovative interconnected trailing edge dive brakes-variable camber flaps. The glider had automatic connection for all controls: ailerons, elevator, air brakes and water ballast. The Mosquito also uses a pneumatic ...

Schempp-Hirth Mini-Nimbus
The Schempp-Hirth Mini Nimbus is a 15 Metre-class glider designed and built by Schempp-Hirth GmbH in the late 1970s. Design and development In designing the Mini-Nimbus, Klaus Holighaus incorporated the flapped wings from the Glasflügel 303 Mosquito, with the fuselage of the Standard Cirrus. The wings feature trailing edge terminal speed dive brakes-variable camber flaps that limit the vertical dive speed to a maximum of 70 knots when the dive brakes are fully deployed. The name "Mini Nimbus" was adopted to distinguish it from longer-wingspan Nimbus models. It first flew on 18 September 1976. The Mini Nimbus range all feature self-connecting controls, of Glasflügel design, for added safety and ease of rigging, and have been incorporated in all newer Schempp-Hirth models. The trim lever is connected to the flap operating rod and needs to be set only once per flight; thereafter changes in flap setting (-7 to +10 degrees) automatically provides trim compensation.
