Weltensegler
Weltensegler G.m.b.H. was a German aircraft company formed by Friedrich Wenk, who became its Technical Director.Lippisch, A.; ''The Delta Wing: History and Development'', Iowa State University 1981, pages 2-4. Wenk developed tailless gliders and entered one in the 1921 Rhön gliding competition held at the Wasserkuppe, from 8 August to 25 August 1921.Hoff, Wilhelm. “Technical memorandum No. 100, Rhön Soaring Flight Competition, 1921”. National Advisory Committee for Aeronautics. Washington D.C.. June 1922. The designer Alexander Lippisch was an employee. History Friedrich Wenk had experimented with model gliders since his teen-age years and discovered that tailless gliders would fly with swept back wings and forward centres of gravity. Stabilising moments in Wenk's designs were provided by swept back wing-tips set with negative incidence relative to the rest of the main-plane.Simons, Martin.

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 ...

Aircraft First Flown In 1921
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 ...

Lippisch Storch V
The RRG Storch V was the only member of Alexander Lippisch's Storch series of tailless aircraft to be powered. It flew successfully in the year 1929. Design and development Before the Storch V, Lippisch had designed only gliders, many of them tailless. The first of these, the Espenlaub E.2, was built by Espenlaub in 1922 but Lippisch, at RRG from 1925, did not return to the tailless layout until 1927. Development progressed with a series of the Storch models; with the Storch IV he achieved a fully controllable aircraft which flew well. The Storch V was essentially the Storch IV with a small pusher configuration engine added behind the pilot. The Storch V had a straight edged wing with about 17° of sweep on the leading edge and with only slight taper and dihedral. It was built around a plywood skinned D-box leading edge spar and a second spar near mid- chord and was fabric covered. Broad, lobate ailerons were hinged at right angles to the line of flight, protruding beyon ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
