Hall Cherokee II
The Hall Cherokee II is an American high-wing, single seat glider that was designed by Stan Hall and introduced in 1956 as plans for amateur construction.Said, Bob: ''1983 Sailplane Directory, Soaring Magazine'', pages 8-9. Soaring Society of America, November 1983. USPS 499-920 Due to its low cost and ease of construction, the Cherokee II is one of the most produced home-built gliders. Design and development The Cherokee was designed by Hall to provide homebuilders with an easy-to-construct and inexpensive aircraft that would give performance at least equal to the Schweizer SGS 1-26, which had flown two years earlier. The Cherokee structure is built from wood and covered in doped aircraft fabric covering. The fuselage features truss construction, with longerons and gussets and a fixed monowheel landing gear. The wing has two spars, with geodetic braces handling the torsion loads and is built with a fixed center section and removable outer wing panels. The wings have spoil ...

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 ...

Glass Reinforced Plastic
Fiberglass (American English) or fibreglass (Commonwealth English) is a common type of fiber-reinforced plastic using glass fiber. The fibers may be randomly arranged, flattened into a sheet called a chopped strand mat, or woven into glass cloth. The plastic matrix may be a thermoset polymer matrix—most often based on thermosetting polymers such as epoxy, polyester resin, or vinyl ester resin—or a thermoplastic. Cheaper and more flexible than carbon fiber, it is stronger than many metals by weight, non-magnetic, non-conductive, transparent to electromagnetic radiation, can be molded into complex shapes, and is chemically inert under many circumstances. Applications include aircraft, boats, automobiles, bath tubs and enclosures, swimming pools, hot tubs, septic tanks, water tanks, roofing, pipes, cladding, orthopedic casts, surfboards, and external door skins. Other common names for fiberglass are glass-reinforced plastic (GRP), glass-fiber reinforced plastic (GFRP) or GFK ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soaring Society Of America
The Soaring Society of America (SSA) was founded at the instigation of Warren E. Eaton to promote the sport of soaring in the USA and internationally. The first meeting was held in New York City in the McGraw–Hill Building on February 20, 1932. Its first objective was to hold a national soaring competition every year, but other roles were quickly adopted. In 1954, the Society created the Soaring Hall of Fame. Today the SSA, with a nationwide membership of over 10,000, is headquartered in Hobbs, New Mexico. It is a 501(c)(3) charity organization. The SSA is led by the 17 members on its board of directors and its executive committee, ten of whom are regionally elected by the general membership and serve for three years. The other seven at-large directors are elected annually by the other directors. In addition to the executive meetings of the board, full SSA Board meetings are held twice a year and are open to the general membership. A support staff administers the daily busin ...
