Skif Raptor
The Skif Raptor is a Ukrainian single-place paraglider that was designed by Sergei Rozhko and produced by Skif Paragliding of Feodosia. It is now out of production.Bertrand, Noel; Rene Coulon; et al: ''World Directory of Leisure Aviation 2003-04'', page 30. Pagefast Ltd, Lancaster OK, 2003. The aircraft is not related to the Independence Raptor. Design and development The Raptor was designed as an advanced and competition glider. The Raptor 29 model is named for its approximate wing area in square metres. The Raptor 29's span wing has 94 cells, a wing area of and an aspect ratio of 5.4:1. The crew weight range is .

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".

Paraglider
Paragliding is the recreational and competitive adventure sport of flying paragliders: lightweight, free-flying, foot-launched glider aircraft with no rigid primary structure. The pilot sits in a harness or lies supine in a cocoon-like 'pod' suspended below a fabric wing. Wing shape is maintained by the suspension lines, the pressure of air entering vents in the front of the wing, and the aerodynamic forces of the air flowing over the outside. Despite not using an engine, paraglider flights can last many hours and cover many hundreds of kilometres, though flights of one to two hours and covering some tens of kilometres are more the norm. By skillful exploitation of sources of lift, the pilot may gain height, often climbing to altitudes of a few thousand metres. History In 1966, Canadian Domina Jalbert was granted a patent for a ''multi-cell wing type aerial device—''"a wing having a flexible canopy constituting an upper skin and with a plurality of longitudinally extend ...

Ukraine
Ukraine ( uk, Україна, Ukraïna, ) is a country in Eastern Europe. It is the second-largest European country after Russia, which it borders to the east and northeast. Ukraine covers approximately . Prior to the ongoing Russian invasion, it was the eighth-most populous country in Europe, with a population of around 41 million people. It is also bordered by Belarus to the north; by Poland, Slovakia, and Hungary to the west; and by Romania and Moldova to the southwest; with a coastline along the Black Sea and the Sea of Azov to the south and southeast. Kyiv is the nation's capital and largest city. Ukraine's state language is Ukrainian; Russian is also widely spoken, especially in the east and south. During the Middle Ages, Ukraine was the site of early Slavic expansion and the area later became a key centre of East Slavic culture under the state of Kievan Rus', which emerged in the 9th century. The state eventually disintegrated into rival regional po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Skif Paragliding
Skif Paragliding is a Ukraine, Ukrainian aircraft manufacturer founded by Sergei Rozhko in 1993 and based in Feodosia. The company specializes in the design and manufacture of paragliders in the form of ready-to-fly aircraft, and also runs a paragliding flight training school.Bertrand, Noel; Rene Coulon; et al: ''World Directory of Leisure Aviation 2003-04'', page 30. Pagefast Ltd, Lancaster UK, 2003. Rozhko is also the designer of the company's paraglider line. The company flight training operation takes place on Klementyeva Mountain. By 2003, the company was offering a line of paragliders, including the beginner to intermediate Skif Skif-A, Skif-A, the competition Skif Raptor, Raptor and the two-place Skif BigSkif Bi, BigSkif Bi for flight training.

Independence Raptor
The Independence Raptor is a German single-place, paraglider that was designed by Michaël Nesler and produced by Independence Paragliding of Eisenberg, Thuringia. It is now out of production.Bertrand, Noel; Rene Coulon; et al: ''World Directory of Leisure Aviation 2003-04'', pages 20 and 30. Pagefast Ltd, Lancaster OK, 2003. ISSN 1368-485X The aircraft is not related to the Skif Raptor. Design and development The Raptor was designed as a competition glider, with an unusually low price as a method of assisting completion pilots. The models are each named for their relative size. Company test pilot Christian Amon was also involved in the development as well as flight testing of the Raptor. Variants ;Raptor S :Small-sized model for lighter pilots. Its span wing has a wing area of , 75 cells and the aspect ratio is 6.34:1. The pilot weight range is . ;Raptor M :Mid-sized model for medium-weight pilots.

Aspect Ratio (wing)
In aeronautics, the aspect ratio of a wing is the ratio of its span to its mean chord. It is equal to the square of the wingspan divided by the wing area. Thus, a long, narrow wing has a high aspect ratio, whereas a short, wide wing has a low aspect ratio.Kermode, A.C. (1972), ''Mechanics of Flight'', Chapter 3, (p.103, eighth edition), Pitman Publishing Limited, London Aspect ratio and other features of the planform are often used to predict the aerodynamic efficiency of a wing because the lift-to-drag ratio increases with aspect ratio, improving the fuel economy in powered airplanes and the gliding angle of sailplanes. Definition The aspect ratio \text is the ratio of the square of the wingspan b to the projected wing area S, which is equal to the ratio of the wingspan b to the standard mean chord \text: \text \equiv \frac = \frac Mechanism As a useful simplification, an airplane in flight can be imagined to affect a circular cylinder of air with a diameter equal to th ...
