U-Turn Infinity
The U-Turn Infinity is a German single-place paraglider, designed and produced by U-Turn GmbH of Villingen-Schwenningen. It was the first glider introduced by the company in 2003 and remained in production in 2016 as the Infinity 4.Bertrand, Noel; Rene Coulon; et al: ''World Directory of Leisure Aviation 2003-04'', page 34. Pagefast Ltd, Lancaster OK, 2003. Design and development The Infinity was designed as an intermediate glider. The design has progressed through four generations of models, the Infinity, Infinity 2, 3 and 4, each improving on the last. The Infinity 4 was a complete redesign and not just an evolution of previous versions. The models are each named for their relative size. Operational history Reviewer Noel Bertrand noted the Infinity's distinctive wing graphics in a 2003 review as "easily recognizable" and noted that the design is "quick and full of promise". Variants Infinity ;Infinity S :Small-sized model for lighter pilots. Its span wing has a wing area ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

A WikiProject, or Wikiproject, is an affinity group for contributors with shared goals within the Wikimedia movement. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within Wikimedia project, sibling 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 Magazine, 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), glider aircraft with no rigid primary structure. The pilot sits in a :wikt:harness, harness or 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 five hours and covering some tens of kilometres are more the norm. By skillful exploitation of sources of lift (soaring), 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 p ...

U-Turn GmbH
U-Turn GmbH is a German aircraft manufacturer originally based in Villingen-Schwenningen and later in Tuningen. The company specializes in the design and manufacture of paragliders in the form of ready-to-fly aircraft, particularly for aerobatics.Bertrand, Noel; Rene Coulon; et al: ''World Directory of Leisure Aviation 2003-04'', page 34. Pagefast Ltd, Lancaster UK, 2003. The company was founded by Thomas Vosseler and Ernst Strobl in 2002. One early innovation was offering glider purchase financing through an owners' club. U-Turn is organized as a Gesellschaft mit beschränkter Haftung (GmbH), a German Limited liability company. The company's first product was the U-Turn Infinity, an intermediate glider designed for easy handling and safety. By 2016 they had a full line of gliders for all levels of pilots, plus aerobatics, including a two-place aerobatic glider, the U-Turn Twinforce.

Villingen-Schwenningen
Villingen-Schwenningen (; Low Alemannic: ''Villinge-Schwenninge'') is a city in the Schwarzwald-Baar district in southern Baden-Württemberg, in south-western Germany. It had 89,743 inhabitants as of September 2024. History In the Middle Ages, Villingen was a town under Austrian lordship. During the Protestant Reformation it remained Catholic. Villingen came to international attention when it was besieged by Marshal of France Camille d'Hostun, duc de Tallard on 17 July 1704. Colonel Von Wilstorff put up a stout defence of the outdated fortifications, and after six days the siege failed. Schwenningen remained a village until the 19th century. In 1858, the first watch factory was established, and watchmaking and precision mechanics have been important industries ever since. The town styled itself "the greatest watch city in the world" at one time, and the Kienzle Uhren watchmaking company was founded there in 1822 and remained until moving to Hamburg in 2002.

Aspect Ratio (aeronautics)
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 cylinder of air with a diameter equal to the wing ...

U-Turn Aircraft
A U-turn in driving refers to performing a 180° rotation to reverse the direction of travel. It is called a "U-turn" because the maneuver looks like the letter U. In some areas, the maneuver is illegal, while in others, it is treated as a more ordinary turn, merely extended. In still other areas, lanes are occasionally marked "U-turn permitted" or even "U-turn only." Occasionally, on a divided highway, special U-turn ramps exist to allow traffic to make a U-turn, though often their use is restricted to emergency and police vehicles only. In the United States, U-turn regulations vary by state: in Indiana U-turns are allowed as long as the driver follows all of the precautions normally ascribed to making a left turn (yielding right-of-way, etc.). Many places, including Texas and Georgia, have specially designed U-turn lanes (referred to as Texas U-turn lanes). In Michigan, U-turns are required for many left turns to and from divided highways, as part of the Michigan left m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
