Spalinger S.18
The Spalinger S.18 is a Swiss 1930s performance sailplane. Several variants were built and the S.18 dominated Swiss contests and set records for nearly a decade. Many were active into the 1960s and four remain on the Swiss register. Design and development In the 1930s Jakob Spalinger designed and built a series of wooden, gull-winged gliders. His 1936 S.18 had a span and modest performance but good handling. Later variants with longer spans improved performance and the type became the dominant Swiss sailplane. The Spalinger S.18 has a high wing with rectangular plan inner panels. On the S.18 II these extend out to 40% span, with strong dihedral over their inner 55% and slight anhedral beyond. The tapered outer panels continue this anhedral out to elliptical tips which have dihedral. The wing has a single main spar with plywood forward of it around the leading edge forming a torsion-resisting D-box. Drag loads are taken by internal diagonal struts from the main spar to the ...

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".

Tailplane
A tailplane, also known as a horizontal stabiliser, is a small lifting surface located on the tail (empennage) behind the main lifting surfaces of a fixed-wing aircraft as well as other non-fixed-wing aircraft such as helicopters and gyroplanes. Not all fixed-wing aircraft have tailplanes. Canards, tailless and flying wing aircraft have no separate tailplane, while in V-tail aircraft the vertical stabiliser, rudder, and the tail-plane and elevator are combined to form two diagonal surfaces in a V layout. The function of the tailplane is to provide stability and control. In particular, the tailplane helps adjust for changes in position of the centre of pressure or centre of gravity caused by changes in speed and attitude, fuel consumption, or dropping cargo or payload. Tailplane types The tailplane comprises the tail-mounted fixed horizontal stabiliser and movable elevator. Besides its planform, it is characterised by: *Number of tailplanes - from 0 ( tailless or canard) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aircraft First Flown In 1936
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-a ...

Altenrhein
Thal is a village and municipality in the ''Wahlkreis'' (constituency) of Rorschach in the canton of St. Gallen in Switzerland. Besides the village of Thal itself, the municipality also includes the villages of Altenrhein, Buechen, Buriet and Staad. History Thal is first mentioned in 1163 as ''curtis tale''. The Weinburg was of regional importance as the seat of noble dynasties (1419-1686), of federal importance as a county recorder's office (1686-1772) and of European importance as the seat of the Prince of Hohenzollern-Sigmaringen (1817-1929). After the First World War, the House of Hohenzollern-Sigmaringen was impoverished and Prince Friedrich von Hohenzollern (1891-1965) was forced to sell the Weinburg estate. The Steyler Mission Society (Societas Verbi Divini, SVD) was found as the buyer. On 2 December 1929, the contract of sale was concluded. One year later, the Weinburg could be opened under the new name Gymnasium Marienburg, first as a mission school. The secondary sc ...

Argentina
Argentina (), officially the Argentine Republic ( es, link=no, República Argentina), is a country in the southern half of South America. Argentina covers an area of , making it the second-largest country in South America after Brazil, the fourth-largest country in the Americas, and the eighth-largest country in the world.

Erich Nessler
The given name Eric, Erich, Erikk, Erik, Erick, or Eirik is derived from the Old Norse name ''Eiríkr'' (or ''Eríkr'' in Old East Norse due to monophthongization). The first element, ''ei-'' may be derived from the older Proto-Norse ''* aina(z)'', meaning "one, alone, unique", ''as in the form'' ''Æ∆inrikr'' explicitly, but it could also be from ''* aiwa(z)'' "everlasting, eternity", as in the Gothic form ''Euric''. The second element ''- ríkr'' stems either from Proto-Germanic ''* ríks'' "king, ruler" (cf. Gothic ''reiks'') or the therefrom derived ''* ríkijaz'' "kingly, powerful, rich, prince"; from the common Proto-Indo-European root * h₃rḗǵs. The name is thus usually taken to mean "sole ruler, autocrat" or "eternal ruler, ever powerful". ''Eric'' used in the sense of a proper noun meaning "one ruler" may be the origin of ''Eriksgata'', and if so it would have meant "one ruler's journey". The tour was the medieval Swedish king's journey, when newly elected, to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Berlin Olympic Games
The 1936 Summer Olympics (German: ''Olympische Sommerspiele 1936''), officially known as the Games of the XI Olympiad (German: ''Spiele der XI. Olympiade'') and commonly known as Berlin 1936 or the Nazi Olympics, were an international multi-sport event held from 1 to 16 August 1936 in Berlin, Germany. Berlin won the bid to host the Games over Barcelona at the 29th IOC Session on 26 April 1931. The 1936 Games marked the second and most recent time the International Olympic Committee gathered to vote in a city that was bidding to host those Games. Later rule modifications forbade cities hosting the bid vote from being awarded the games. To outdo the 1932 Los Angeles Games, Reich Führer Adolf Hitler had a new 100,000-seat track and field stadium built, as well as six gymnasiums and other smaller arenas. The Games were the first to be televised, with radio broadcasts reaching 41 countries.Rader, Benjamin G. "American Sports: From the Age of Folk Games to the Age of Televised Spo ...

Chord (aeronautics)
In aeronautics, the chord is an imaginary straight line joining the leading edge and trailing edge of an aerofoil. The chord length is the distance between the trailing edge and the point where the chord intersects the leading edge. L. J. Clancy (1975), ''Aerodynamics'', Section 5.2, Pitman Publishing Limited, London. The point on the leading edge used to define the chord may be the surface point of minimum radius. p.18 For a turbine aerofoil the chord may be defined by the line between points where the front and rear of a 2-dimensional blade section would touch a flat surface when laid convex-side up. The wing, horizontal stabilizer, vertical stabilizer and propeller/rotor blades of an aircraft are all based on aerofoil sections, and the term ''chord'' or ''chord length'' is also used to describe their width. The chord of a wing, stabilizer and propeller is determined by measuring the distance between leading and trailing edges in the direction of the airflow. (If a win ...
