Apco Presta
The Apco Presta is an Israeli single-place, paraglider that was designed and produced by Apco Aviation of Caesarea. It is now out of production.Bertrand, Noel; Rene Coulon; et al: ''World Directory of Leisure Aviation 2003-04'', page 12. Pagefast Ltd, Lancaster OK, 2003. ISSN 1368-485X Design and development The Presta was designed as an intermediate glider, to fit in the company's line between the Apco Allegra and the Bagheera, with higher performance than the Allegra. The sail is made from 46gr/m2 "Zero Porosity" ripstop nylon Nylon is a generic designation for a family of synthetic polymers composed of polyamides ( repeating units linked by amide links).The polyamides may be aliphatic or semi-aromatic. Nylon is a silk-like thermoplastic, generally made from petro .... The design uses an ''Active Double Valve System'' to allow closed cells to be easily inflated on launch.

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 Wikimedia project, 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 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 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 (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 s ...

Israel
Israel (; he, יִשְׂרָאֵל, ; ar, إِسْرَائِيل, ), officially the State of Israel ( he, מְדִינַת יִשְׂרָאֵל, label=none, translit=Medīnat Yīsrāʾēl; ), is a country in Western Asia. It is situated on the Eastern Mediterranean, southeastern shore of the Mediterranean Sea and the northern shore of the Red Sea, and Borders of Israel, shares borders with Lebanon to the north, Syria to the northeast, Jordan to the east, and Egypt to the southwest. Israel also is bordered by the Palestinian territories of the West Bank and the Gaza Strip to the east and west, respectively. Tel Aviv is the Economy of Israel, economic and Science and technology in Israel, technological center of the country, while its seat of government is in its proclaimed capital of Jerusalem, although Status of Jerusalem, Israeli sovereignty over East Jerusalem is unrecognized internationally.

Apco Aviation
Apco Aviation (usually styled APCO), is an Israeli aircraft manufacturer based in Caesarea and founded in 1982 by Anatoly Cohn. The company specializes in the design and manufacture of paragliders and at one time also made hang gliders and ultralight aircraft. It also manufacturers paraglider harnesses, the Mayday line of parachute rescue systems and other accessories.Bertrand, Noel; Rene Coulon; et al: ''World Directory of Leisure Aviation 2003-04'', page 12. Pagefast Ltd, Lancaster UK, 2003. Cohn started building his first prototype hang glider in 1974. In 1978 he produced his first high performance hang glider and in 1982 started Apco Aviation. The company started producing paragliders in 1986 and has built more than 40 different models. It produces a wide range of paragliders that has included the competition Apco Simba, the Prima trainer, the Fiesta beginner glider, the intermediate Presta and Keara. The company occupies a factory in northern Israel that was spec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Caesarea, Israel
Caesarea (; he, קֵיסָרְיָה, , ''Keysariya'' or ''Qesarya''), also transliterated as Keisarya or Qaysaria, is an affluent town in north-central Israel, which was named after the ancient city of Caesarea Maritima situated to the south. Located midway between Tel Aviv and Haifa on the coastal plain near the city of Hadera, it falls under the jurisdiction of Hof HaCarmel Regional Council. With a population of , it is the only Israeli locality managed by a private organization, the Caesarea Development Corporation, and also one of the most populous localities not recognized as a local council. History Ancient Caesarea The modern town is named after the nearby ancient city of Caesarea Maritima, built by Herod the Great about 25–13 BCE as a major port. It served as an administrative center of the province of Judaea (later named Syria Palaestina) in the Roman Empire, and later as the capital of the Byzantine province of Palaestina Prima.

Nylon
Nylon is a generic designation for a family of synthetic polymers composed of polyamides ( repeating units linked by amide links).The polyamides may be aliphatic or semi-aromatic. Nylon is a silk-like thermoplastic, generally made from petroleum, that can be melt-processed into fibers, films, or shapes. Nylon polymers can be mixed with a wide variety of additives to achieve many property variations. Nylon polymers have found significant commercial applications in fabric and fibers (apparel, flooring and rubber reinforcement), in shapes (molded parts for cars, electrical equipment, etc.), and in films (mostly for food packaging). History DuPont and the invention of nylon Researchers at DuPont began developing cellulose based fibers, culminating in the synthetic fiber rayon. DuPont's experience with rayon was an important precursor to its development and marketing of nylon. DuPont's invention of nylon spanned an eleven-year period, ranging from the initial researc ...

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 t ...
