Siemens-Halske Sh 12
The Siemens-Halske Sh 12 was a nine-cylinder, air-cooled, radial engine for aircraft built in Germany in the 1920s. First run in 1925, it was rated at 80 kW (110 hp). The Sh 12 was also produced in the United States by Ryan Aeronautical Corp. as the Ryan-Siemens 9.

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".

Aircraft Air-cooled Radial Piston Engines
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 ...

VL Sääski
VL Sääski II (English: mosquito) was the first series-produced aircraft designed in Finland. The aircraft was built by the State Aircraft Factory (''Valtion lentokonetehdas'') (abbreviated either V.L. or VL) and was a two-seat, biplane, single-engine trainer constructed out of wood. Design and development The aircraft was designed by Kurt Berger and Asser Järvinen in 1927 and the prototype was financed by the ten-person construction team that built the aircraft in the A.E. Nyman workshop. The prototype was called Sääski I and was completed in the early spring of 1928. The aircraft's civil registration code was "K-SASA" and it was sold to the Finnish Air Force on June 25, 1928. The constructors of the aircraft formed a company called ''Sääski'' in 1928, obtained the manufacturing license from the designers, and had four improved Sääski II's built by the State Aircraft Company for civilian use. When a lack of orders threatened to drive the company to bankruptcy, the FAF ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Udet U 12
The Udet U 12 Flamingo was an aerobatic sports plane and trainer aircraft developed in Germany in the mid-1920s. Design and development The U 12 was a conventional, single-bay biplane of wooden construction with the wings braced by large I-struts. The pilot and instructor or passenger sat in tandem, open cockpits. The U 12 proved extremely popular and sold well, due in no small part to Ernst Udet's spectacular aerobatics routines while flying the aircraft. One particularly acclaimed part of his act included swooping down towards the airfield and picking up a handkerchief with the tip of one wing. The popularity of this aircraft was insufficient to rescue Udet Flugzeugbau from its dire financial position, but when the company's assets were taken over by the state of Bavaria to form BFW, production of the U 12 soon resumed in earnest. BFW-built U 12s were exported to Austria, Hungary and Latvia, and later built under licence in these countries as well. Variants Germany * U 12a ...

Udet U 11 Kondor
The Udet U 11 Kondor was a German four-engined airliner designed and built by Udet Flugzeugbau, only one was built. Design and development The U 11 Kondor was an open-cockpit, metal-fuselage, wooden high-wing monoplane powered by four Siemens-Halske Sh 12 piston engines in shaft-driven pusher configuration. It had a crew of three and room for eight passengers with a dangerously close clearance between the pusher propellers and rear passenger door, which caused one fatality. The aircraft was tested by Harry Rother near Munich, finding a tail-heavy condition which required addition of larger control surfaces. The only U 11 was first flown on 19 January 1926 and was refused by Deutsche Luft-Reederei then purchased by Deutsche Luft Hansa ''Deutsche Luft Hansa A.G.'' (from 1933 styled as ''Deutsche Lufthansa'' and also known as ''Luft Hansa'', ''Lufthansa'', or DLH) was a German airline, serving as flag carrier of the country during the later years of the Weimar Republic and ...

Udet U 8
The parasol wing, single engine Udet U 8, sometimes referred to as the Limousine, was a three-seat commercial passenger transport designed and built in Germany in 1924. Five were produced and were used by German airlines until about 1928. Design and development The first Udet passenger transport was the two-passenger U 5, which appeared in 1923. This was powered by a , seven-cylinder, Siemens-Halske Sh 5 radial engine. The following year Udet produced the first U 8, which had a nine-cylinder, Siemens-Halske Sh 6 radial, making it rather heavier than the U 5 but leaving the design only slightly changed and the dimensions unaltered. The new engine allowed the U 8 to carry three passengers. The cantilever, one-piece parasol wing of the U.8 was trapezoidal in plan, with long, elliptical tips. It had a thick section which thinned outwards and was built around two spruce box spars and fabric covered. Its ailerons tapered in chord out to the wing tips; together, they occupied ...

Raab-Katzenstein KL
Raab-Katzenstein was a 1920s German aircraft manufacturer based in Kassel. History The main character of the company was its designer Gerhard Fieseler. Following World War I, he returned to printing, but yearned to return to flying. In 1926, he closed his print shop in Eschweiler and became a flight instructor with Raab-Katzenstein and continued to hone his flying skills, becoming an accomplished stunt pilot. In 1927, he performed a particularly daring routine in Zürich and started to command increasingly high fees for appearances. In 1928 while working at Raab-Katzenstein, he designed his own stunt plane, the Fieseler F1 (also known as the Raab-Katzenstein RK-26 Tigerschwalbe), which was offered and sold to a Swedish company called AB Svenska Järnvägverkstaderna (ASJA), which built 25 of the type for Swedish Air Force in the beginning of the 1930s. In 1930, Raab-Katzenstein was bankrupt, and Fieseler decided to strike out on his own. Using money he had been saving from his aer ...

Command-Aire 3C3-B
The Command-Aire 3C3 and similar 4C3 and 5C3 are United States, American three-seat open cockpit utility, training and touring biplanes developed by Command-Aire in the late 1920s and early 1930s. Design and Development The Command-Aire did not at first appear to offer much of an advancement over the vast multitude of three seat biplanes built around the ubiquitous Curtiss OX-5 engine to similar designs, with similar dimensions and construction methods, many of which were already in production. Indeed, the OX-5 era was coming to an end. The vast quantities of war-surplus engines, which had swamped the market in the immediate post-war period, were running low. Only by the smaller details can it be distinguished from its brethren. The basic design was by Morton Cronk, and although it had excellent high altitude capabilities, it was slow. This setback nearly foundered the company before its first aircraft entered production. The design's proportions were good though, but his depar ...
