Scheibe Tandem-Falke
The Scheibe SF 28 Tandem-''Falke'' (English: "falcon") is a German motorglider that was designed by Egon Scheibe in 1970 and which flew for the first time in May the following year. It was a development of the Scheibe Falke with (as its name suggests) seating in tandem rather than side-by-side as in the original Falke design. Development The SF 28 is a low-wing, cantilever monoplane of conventional design with a large perspex canopy. The undercarriage consists of a non-retractable monowheel and a steerable tailwheel, linked to the rudder. Small outrigger wheels are fitted to nylon legs under each wing. The fuselage is of steel tube construction, covered in fabric and the wings are constructed of wood and fabric around a single spar. Operational history Scheibe entered at least one Tandem-Falke in the German Motor Glider Competition of 1977. At least one SF28 was used by the Spanish military as 'UE 16-1' and demobilized in April 2008. Specifications (SF 28A) See also No ...

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".

Göttingen 533
Göttingen (, , ; nds, Chöttingen) is a university city in Lower Saxony, central Germany, the capital of the eponymous district. The River Leine runs through it. At the end of 2019, the population was 118,911. General information The origins of Göttingen lay in a village called ''Gutingi, ''first mentioned in a document in 953 AD. The city was founded northwest of this village, between 1150 and 1200 AD, and adopted its name. In medieval times the city was a member of the Hanseatic League and hence a wealthy town. Today, Göttingen is famous for its old university (''Georgia Augusta'', or "Georg-August-Universität"), which was founded in 1734 (first classes in 1737) and became the most visited university of Europe. In 1837, seven professors protested against the absolute sovereignty of the kings of Hanover; they lost their positions, but became known as the " Göttingen Seven". Its alumni include some well-known historical figures: the Brothers Grimm, Heinrich Ewa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Motor Gliders
An engine or motor is a machine designed to convert one or more forms of energy into mechanical energy. Available energy sources include potential energy (e.g. energy of the Earth's gravitational field as exploited in hydroelectric power generation), heat energy (e.g. geothermal), chemical energy, electric potential and nuclear energy (from nuclear fission or nuclear fusion). Many of these processes generate heat as an intermediate energy form, so heat engines have special importance. Some natural processes, such as atmospheric convection cells convert environmental heat into motion (e.g. in the form of rising air currents). Mechanical energy is of particular importance in transportation, but also plays a role in many industrial processes such as cutting, grinding, crushing, and mixing. Mechanical heat engines convert heat into work via various thermodynamic processes. The internal combustion engine is perhaps the most common example of a mechanical heat engine, in which he ...

1970s German Sailplanes
Year 197 ( CXCVII) was a common year starting on Saturday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Magius and Rufinus (or, less frequently, year 950 ''Ab urbe condita''). The denomination 197 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Aircraft Fabric Covering
Aircraft fabric covering is a term used for both the material used and the process of covering aircraft open structures. It is also used for reinforcing closed plywood structures. The de Havilland Mosquito is an example of this technique, as are the pioneering all-wood monocoque fuselages of certain World War I German aircraft like the LFG Roland C.II in its wrapped ''Wickelrumpf'' plywood strip and fabric covering. Early aircraft used organic materials such as cotton and cellulose nitrate dope; modern fabric-covered designs usually use synthetic materials such as Dacron and butyrate dope for adhesive. Modern methods are often used in the restoration of older types that were originally covered using traditional methods. Purpose/requirements The purposes of the fabric covering of an aircraft are: * To provide a light airproof skin for lifting and control surfaces. * To provide structural strength to otherwise weak structures. * To cover other non-lifting parts of an airc ...

Scheibe Falke
The Scheibe SF-25 Falke ( en, Falcon) is a German touring motor glider developed from the earlier Bergfalke glider by Scheibe Flugzeugbau. Since May 2006 the business has been run by Scheibe Aircraft GmbH. Development The company had produced the Motor Spatz but decided to produce a better light aircraft based on the Bergfalke glider. It had a new forward fuselage with an enclosed cockpit with two side-by-side seats and originally a Hirth F10A2a engine in the nose. It first flew in May 1963 as the SF-25A Motor Falke. After an initial batch of aircraft the wing was lowered and it was renamed as just the SF-25B Falke. A number of variants were built with various engines and the type was licence built by Sportavia-Putzer, Aeronautica Umbra (Italy), Loravia (France) and Slingsby (United Kingdom). The current model is the SF 25C. It is currently available with a choice of three engines: the Rotax 912 80 hp, the Rotax 912S (100 hp) and the Rotax 914F3 (115 hp). V ...
