Neukom Elfe
The Neukom Elfe is family of Swiss single-seat high-performance sailplane designs. The aircraft is a shoulder-wing cantilever monoplane with a wing made from a balsa and plywood sandwich covered in fiberglass and a fuselage built from plywood. Design and development Elfe and Elfe 2 The first Elfe was a 9-metre wingspan glider that was designed by Swiss designer W. Pfenninger before World War II. A new design was introduced by Pfenninger in 1947 and was named the Elfe 2. This was probably the first sailplane to feature a laminar flow airfoil. It crashed due to rudder flutter PM-3 The Elfe series was then taken over, improved and strengthened by the Swiss engineer Markwalder into a third prototype, called the Elfe PM-3.Said, Bob: ''1983 Sailplane Directory, Soaring Magazine'', page 79. Soaring Society of America, November 1983. USPS 499–920 The sole PM-3's construction was started in one factory, but finished in another. It was first flown in 1955 and then went into stor ...

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 ...

V-tail
The V-tail or ''Vee-tail'' (sometimes called a butterfly tail or Rudlicki's V-tailGudmundsson S. (2013). "General Aviation Aircraft Design: Applied Methods and Procedures" (Reprint). Butterworth-Heinemann. p. 489. , 9780123973290) of an aircraft is an unconventional arrangement of the tail control surfaces that replaces the traditional fin and horizontal surfaces with two surfaces set in a V-shaped configuration. It is not widely used in aircraft design. The aft edge of each twin surface is a hinged control surface called a ruddervator, which combines the functions of both a rudder and elevator. The V-tail was invented in 1930 by Polish engineer Jerzy Rudlicki and was tested for the first time on the Hanriot H-28 trainer aircraft, modified by a Polish aerospace manufacturer Plage and Laśkiewicz in the summer of 1931. Variants The X-shaped tail surfaces of the experimental Lockheed XFV were essentially a V tail that extended both above and below the fuselage. Conventional ...

1960s Swiss Sailplanes
Year 196 ( CXCVI) was a leap year starting on Thursday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Dexter and Messalla (or, less frequently, year 949 '' Ab urbe condita''). The denomination 196 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.

Leszno
Leszno (german: Lissa, 1800–1918 ''Lissa in Posen'') is a historic city in western Poland, within the Greater Poland Voivodeship. It is the seventh-largest city in the province with an estimated population of 62,200, as of 2021. Previously, it was the capital of the Leszno Voivodeship (1975–1998) and is now the seat of Leszno County. History Early history The city's unrecorded history dates to the 13th century. It was first mentioned in historical documents in 1393, when the estate was the property of a noble named Stefan Karnin- Wieniawa. The family eventually adopted the name Leszczyński (literal meaning "of Leszno"), derived from the name of their estate, as was the custom among the Polish nobility. 16th–18th centuries In around 1516, a community of Protestants known as the Unity of the Brethren (''Unitas fratrum'') were expelled from the Bohemian lands by King Vladislaus II and settled in Leszno. They were invited by the Leszczyński family, imperial counts since ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Cerney
South Cerney is a village and civil parish in the Cotswold district of Gloucestershire, 3 miles south of Cirencester and close to the border with Wiltshire. It had a population of 3,074 according to the 2001 census, increasing to 3,464 at the 2011 census. It was founded in 999 by Saxon settlers, with a charter by King Aethelred II. In 2001 South Cerney was winner of the Bledisloe Cup for the best-kept village in Gloucestershire (large village class), having previously won the award in 1955. Church of All Hallows, South Cerney and Ann Edwards School Two fragments of a carved wooden crucified Christ, a head and a foot, were found in 1915 concealed in a wall of the village church. The crucifix was probably hidden at the time of the Reformation but mostly disintegrated due to the damp. Part of a crucifix that dates from the 12th century, it is one of very few early-medieval wooden sculptures of Christ extant in England, and would have been part of the 'rood' that stood above ...

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.

Cruciform Tail
__NOTOC__ The cruciform tail is an aircraft empennage configuration which, when viewed from the aircraft's front or rear, looks much like a cross. The usual arrangement is to have the horizontal stabilizer intersect the vertical tail somewhere near the middle, and above the top of the fuselage. The design is often used to locate the horizontal stabilizer away from jet exhaust, propeller and wing wake, as well as to provide undisturbed airflow to the rudder. Prominent examples of aircraft with cruciform tails include the Avro Canada CF-100 Canuck, the British Aerospace Jetstream 31, the Fairchild Swearingen Metroliner, and the Rockwell B-1 Lancer.

FAI Standard Class
Competition classes in gliding, as in other sports, mainly exist to ensure fairness in competition. However the classes have not been targeted at fostering technological development as in other sports. Instead classes have arisen because of: * the popularity of certain types of glider * attempts to contain the cost of access to the sport * the need to establish a stable environment for investment decisions by both manufacturers and competitors. The FAI Gliding Commission (IGC) is the sporting body overseeing air sports at the international level so that essentially the same classes and class definitions are followed in all countries. FAI Competition Classes Seven glider classes are currently recognised by the FAI and are eligible for European and World Championships: * Open Class, places no restrictions except a limit of 850 kg to the maximum all-up mass, may be one- or two-seater e.g. JS-1C, Lange Antares 23E, Quintus, ASW 22, ASH 30, LAK-20. * Standard Class, restri ...
