Paratech P43
The Paratech P43 is a Swiss single-place paraglider that was designed by Uwe Bernholz and produced by Paratech of Appenzell. It was introduced in 2003, but is now out of production.Bertrand, Noel; Rene Coulon; et al: ''World Directory of Leisure Aviation 2003-04'', page 26. Pagefast Ltd, Lancaster OK, 2003. Design and development The aircraft was designed as an intermediate glider. The wing design includes "Permanent Air Flow", a feature by which the cell openings are made smaller to improve the leading edge The leading edge of an airfoil surface such as a wing is its foremost edge and is therefore the part which first meets the oncoming air.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 305.

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 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 exte ...

Paratech
Paratech AG was a Swiss aircraft manufacturer based in Wasserauen and previously in Appenzell. The company specialized in the design and manufacture of paragliders in the form of ready-to-fly aircraft, as well as paragliding harnesses, clothing and accessories.Bertrand, Noel; Rene Coulon; et al: ''World Directory of Leisure Aviation 2003-04'', page 26. Pagefast Ltd, Lancaster UK, 2003. The company was founded in 1988 and seems to gone out of business in 2015. The company was an aktiengesellschaft, a stockholder owned company. Paratech's paragliders, designed by Uwe Bernholz, had a unique model numbering system. In the early 2000s production included the beginner P25 and P26, the intermediate P43 and the performance P70, as well as the two-place P Bi4 for flight training.

Euro
The euro ( symbol: €; code: EUR) is the official currency of 19 out of the member states of the European Union (EU). This group of states is known as the eurozone or, officially, the euro area, and includes about 340 million citizens . The euro is divided into 100 cents. The currency is also used officially by the institutions of the European Union, by four European microstates that are not EU members, the British Overseas Territory of Akrotiri and Dhekelia, as well as unilaterally by Montenegro and Kosovo. Outside Europe, a number of special territories of EU members also use the euro as their currency. Additionally, over 200 million people worldwide use currencies pegged to the euro. As of 2013, the euro is the second-largest reserve currency as well as the second-most traded currency in the world after the United States dollar. , with more than €1.3 trillion in circulation, the euro has one of the highest combined values of banknotes and coins in ci ...

Appenzell (town)
Appenzell is a village, a town, and the capital of the canton of Appenzell Innerrhoden in Switzerland. Appenzell has no municipal government of its own; rather, the different parts of Appenzell belong to and are governed by the districts (and municipalities) Appenzell, Schwende and Rüte. Because of that, for firefighting, energy and water, the village Appenzell has a special-purpose municipality, the Feuerschaugemeinde. History In 1071 the village was referred to as ''Abbacella''. By 1223 this changed to ''Abbatiscella'', meaning the Abbot's cell. This refers to the abbot of the Abbey of Saint Gall. The buildings in the village core, the parish church, the 1563 town hall, the ''Salesis'' house, the ruins of Castle Clanx and the state archives with the administration building are listed as heritage sites of national significance.

Leading Edge
The leading edge of an airfoil surface such as a wing is its foremost edge and is therefore the part which first meets the oncoming air.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 305. Aviation Supplies & Academics, 1997. Characteristics Sweep Seen in plan the leading edge may be straight, curved, kinked or a combination of these. A straight leading edge may be swept or unswept, while curves or kinks always mean that part of the leading edge is swept. On a swept wing the sweep angle may differ from that of the wing, as wing sweep is conventionally measured at the airfoil 25% chord line. However on a delta wing the leading edge sweep defines the wing sweep. Radius and stagnation point A rounded leading edge helps to maintain a smooth airflow at varying angles of incidence to the airflow. Most subsonic airfoils therefore have a rounded leading edge. The degree of rounding is characterised by the profile radius at that point. The airflow divides ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 circular cylinder of air with a diameter equal to ...
