1-21
The Schweizer SGS 1-21 is a United States single-seat, mid-wing, Open Class glider built by Schweizer Aircraft of Elmira, New York.Schweizer, Paul A: ''Wings Like Eagles, The Story of Soaring in the United States'', pages 99-111. Smithsonian Institution Press, 1988. The 1-21 was a clean-sheet design intended to fill the role of high performance competition sailplane. It was designed by Ernest Schweizer and first announced in the September–October 1946 issue of the Soaring Society of America's ''Soaring'' magazine. Design and development Following World War II soaring in the United States was dominated by surplus two-place gliders that had been used as trainers by the military, such as the TG-1, TG-2 and TG-3. By the end of the war there were only about 400 gliders in the US. Of these only about a dozen were high performance competition sailplanes and half of these were pre-war designs. Schweizer Aircraft realized that if the US was to progress in the sport of soaring, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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 ...

Lift (soaring)
Lift is a meteorological phenomenon used as an energy source by soaring aircraft and soaring birds. The most common human application of lift is in sport and recreation. The three air sports that use soaring flight are: gliding, hang gliding and paragliding. Energy can be gained by using rising air from four sources: * Thermals (where air rises due to heat), * Ridge lift, where air is forced upwards by a slope, * Wave lift, where a mountain produces a standing wave, * Convergence, where two air masses meet In dynamic soaring it is also possible to gain energy, though this uses differences in wind speeds rather than rising air. Thermals Thermals are columns of rising air that are formed on the ground through the warming of the surface by sunlight. If the air contains enough moisture, the water will condense from the rising air and form cumulus clouds. Thermal lift is often used by birds, such as raptors, vultures and storks. Although thermal lift was known to the Wright Brot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1940s United States Sailplanes
Year 194 ( CXCIV) was a common year starting on Tuesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Septimius and Septimius (or, less frequently, year 947 ''Ab urbe condita''). The denomination 194 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 * Emperor Septimius Severus and Decimus Clodius Septimius Albinus Caesar become Roman Consuls. * Battle of Issus: Septimius Severus marches with his army (12 legions) to Cilicia, and defeats Pescennius Niger, Roman governor of Syria.

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] |
Richland, Washington
Richland () is a city in Benton County, Washington, United States. It is located in southeastern Washington at the confluence of the Yakima and the Columbia Rivers. As of the 2020 census, the city's population was 60,560. Along with the nearby cities of Pasco and Kennewick, Richland is one of the Tri-Cities, and is home to the Hanford nuclear site. History For centuries, the village of Chemna stood at the mouth of the current Yakima River. Today that village site is called Columbia Point. From this village, the Wanapum, Yakama and Walla Walla Indians harvested the salmon runs entering the Yakima River. Captain William Clark of the Lewis and Clark Expedition visited the mouth of the Yakima River on October 17, 1805. Formative years In 1904–1905, W.R. Amon and his son Howard purchased and proposed a town site on the north bank of the Yakima River. Postal authorities approved the designation of this town site as Richland in 1905, naming it for Nelson Rich, a state legislat ...

Schweizer SGS 1-23
The Schweizer SGS 1-23 is a United States Open and Standard Class, single-seat, mid-wing glider built by Schweizer Aircraft of Elmira, New York. The original "standard" 1-23 was introduced in 1948. The aircraft quickly became the most numerous competition and performance sailplane in the USA. A total of 93 of all sub-models were built by the time production was completed in 1967. Design and development Schweizer Aircraft started construction of the 1-23 prototype in May 1948. The aircraft was completed and first flew on 5 July 1948, only nine weeks after construction had begun. The prototype had been ordered by Bill Frutchy of Elmira, New York and the aircraft was available for him to fly it in the second half of the US Nationals. The first production 1-23 was ordered by E.J Reeves. The success of this aircraft led to more orders and series production was commenced. The 1-23 was initially sold on a "factory direct" basis, which allowed them to be sold at a lower price than t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
