Akaflieg Stuttgart FS-29
The Akaflieg Stuttgart fs29 TF ''Stadt Stuttgart'' is a glider designed and built in Germany from 1972. Development The fs29 was designed and built to research the telescopic variable span wing. With the wing at full extension the fs29 could thermal successfully in very weak conditions and land safely in small spaces, conversely with the wing fully retracted the fs29 could cruise between lift at higher speeds, improving performance in distance/speed competitions, as well as perform aerobatics to higher load factors with faster control response. Construction of the fs29 was as follows:- *Inner wing: ** Spar: Carbon Fibre Epoxy. ** Skin: Glassfibre Re-inforced Epoxy + Foam Sandwich. *Outer wing: ** Rectangular section: Carbon Fibre Epoxy Skin. ** Trapezoidal Section: Glassfibre Re-inforced Epoxy + Foam Sandwich. *Fuselage Structure: Welded steel tubing. *Cockpit: Glassfibre Re-inforced Epoxy + Foam Sandwich . *Tail Boom Skin: Aluminum Alloy. *Tail Unit: Glassfibre Re-inforced Ep ...

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 ...

Akaflieg Braunschweig SB-13 Arcus
The Akaflieg Braunschweig SB-13 Arcus was an experimental tailless, single seat, Standard Class glider designed and built in Germany in the early 1990s. Though it performed as well as its conventional contemporaries, it did not offer sufficiently improved performance to compensate for its difficult handling characteristics. Design and development The Akaflieg Braunschweig or Akademische Fliegergruppe Braunschweig ( en, The Brunswick Academic Flying Group) is one of some fourteen German undergraduate student flying groups attached to and supported by their home Technical University. Several have designed and built aircraft, often technically advanced and leading the development of gliders in particular. In 1982 when the SB-13 design was first discussed no new tailless glider had been built for thirty years, during which time glass reinforced plastic materials had replaced wood in glider construction and much learned about laminar flow wings; it was hoped that tailless designs ...

Aircraft First Flown In 1975
An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-air ball ...
