Alexander Soldenhoff
Alexander Leo Soldenhoff (1882–1951) was a Swiss artist and aircraft designer. Born in Switzerland, he lived much of his life in Germany. In 1906 he married Anna Zweifler from Glarus. They separated in 1947, only a few years before his death. Painting Soldenhoff trained as an artist and during the early 1900s was employed as an art teacher. His aeronautical work interrupted his career as a painter, but he would return to it from time to time when he ran out of money to build more aeroplanes. Aircraft Soldenhoff became interested in aviation during the pioneer years of the twentieth century. After the end of WWI he determined to develop a tailless, swept-wing "safety aeroplane" after the manner of designs already produced from 1909. He built his first full-size glider and began attempts to fly in 1915. He completed the ''Bülbül I'' in July 1928 and entered it in that year's Rhön competition but it was blown backwards and damaged before he could launch it. His subsequent ...

Switzerland
Switzerland, officially the Swiss Confederation, is a landlocked country located in west-central Europe. It is bordered by Italy to the south, France to the west, Germany to the north, and Austria and Liechtenstein to the east. Switzerland is geographically divided among the Swiss Plateau, the Swiss Alps, Alps and the Jura Mountains, Jura; the Alps occupy the greater part of the territory, whereas most of the country's Demographics of Switzerland, 9 million people are concentrated on the plateau, which hosts List of cities in Switzerland, its largest cities and economic centres, including Zurich, Geneva, and Lausanne. Switzerland is a federal republic composed of Cantons of Switzerland, 26 cantons, with federal authorities based in Bern. It has four main linguistic and cultural regions: German, French, Italian and Romansh language, Romansh. Although most Swiss are German-speaking, national identity is fairly cohesive, being rooted in a common historical background, shared ...

Tailless Aircraft
In aeronautics, a tailless aircraft is a fixed-wing aircraft with no other horizontal aerodynamic surface besides its main wing. It may still have a fuselage, vertical tail fin (vertical stabilizer), and/or vertical rudder. Theoretical advantages of the tailless configuration include low parasitic drag as on the Horten H.IV soaring glider and good stealth characteristics as on the Northrop B-2 Spirit bomber. Disadvantages include a potential sensitivity to trim. Tailless aircraft have been flown since the pioneer days; the first stable aeroplane to fly was the tailless Dunne D.5, in 1910. The most successful tailless configuration has been the tailless delta, especially for combat aircraft, though the Concorde airliner is also a delta configuration. NASA has used the 'tailless' description for the novel X-36 research aircraft which has a canard foreplane but no vertical fin. Aircraft configuration A tailless aircraft has no other horizontal surface besides its main wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Swept Wing
A swept wing is a wing angled either backward or occasionally forward from its root rather than perpendicular to the fuselage. Swept wings have been flown since the pioneer days of aviation. Wing sweep at high speeds was first investigated in Germany as early as 1935 by Albert Betz and Adolph Busemann, finding application just before the end of the Second World War. It has the effect of delaying the shock waves and accompanying aerodynamic drag rise caused by fluid compressibility near the speed of sound, improving performance. Swept wings are therefore almost always used on jet aircraft designed to fly at these speeds. The term "swept wing" is normally used to mean "swept back", but variants include forward sweep, variable sweep wings and oblique wings in which one side sweeps forward and the other back. The delta wing is also aerodynamically a form of swept wing. Reasons for sweep There are three main reasons for sweeping a wing: 1. to arrange the center of gravity o ...

Glider (aircraft)
A glider is a fixed-wing aircraft that is supported in flight by the dynamic reaction of the air against its lifting surfaces, and whose free flight does not depend on an engine. Most gliders do not have an engine, although motor-gliders have small engines for extending their flight when necessary by sustaining the altitude (normally a sailplane relies on rising air to maintain altitude) with some being powerful enough to take off by self-launch. There are a wide variety of types differing in the construction of their wings, aerodynamic efficiency, location of the pilot, controls and intended purpose. Most exploit meteorological phenomena to maintain or gain height. Gliders are principally used for the air sports of gliding, hang gliding and paragliding. However some spacecraft have been designed to descend as gliders and in the past military gliders have been used in warfare. Some simple and familiar types of glider are toys such as paper planes and balsa wood glider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pusher Propeller
In aeronautical and naval engineering, pusher configuration is the term used to describe a drivetrain of air- or watercraft with propulsion device(s) after the engine(s). This is in contrast to the more conventional tractor configuration, which places them in front. Though the term is most commonly applied to aircraft, its most ubiquitous propeller example is a common outboard motor for a small boat. “Pusher configuration” describes the specific (propeller or ducted fan) thrust device attached to a craft, either aerostats (airship) or aerodynes (aircraft, WIG, paramotor, rotorcraft) or others types such as hovercraft, airboats, and propeller-driven snowmobiles. History The rubber-powered "Planophore", designed by Alphonse Pénaud in 1871, was an early successful model aircraft with a pusher propeller. Many early aircraft (especially biplanes) were "pushers", including the Wright Flyer (1903), the Santos-Dumont 14-bis (1906), the Voisin-Farman I (1907), and ...

Gottlob Espenlaub
Gottlob Espenlaub (25 October 1900 – 9 January 1972), nicknamed Espe, was an inventor who specialized in early types of aircraft, specifically gliders and rocket propulsion systems designed for them. He invented a number of different aircraft, focusing on tailless designs. Espenlaub co-founded the practice of aerotowing. Aeronautic career Espenlaub was born in Balzholz, since 1938 part of Beuren. As a young man Espenlaub served as a joiner to aircraft builders. He helped Alexander Lippisch to build a style of glider in 1921 according to Lippisch's designs. The glider was subsequently dubbed the Lippisch-Espenlaub E-2 glider, due to Espenlaub's participation in its creation. Espenlaub began building his own rocket propelled gliders in 1928, conducting his first rocket test on October 22, 1929. His rocket glider for this test was dubbed the RAK-3 and it featured missiles attached to the wings. During the flight, these missiles caught the tail on fire, forcing an early l ...

Swiss Museum Of Transport
The Swiss Museum of Transport or ''Verkehrshaus der Schweiz'' (literally "Transportation House of Switzerland") in Lucerne opened in July 1959 and exhibits all forms of transport including trains, automobiles, ships and aircraft as well as communication technology. It is Switzerland's most popular museum. The museum also maintains a large collection of work by Hans Erni, a local painter and sculptor. There are several other attractions in the museum besides the collection, including a planetarium, a large-format cinema and a 1:20,000 scale aerial photograph of Switzerland. History The museum traces its history to 1897, when the first attempts at creating a museum of railway equipment were made. Following a national exhibition in 1914, the Swiss Railway Museum was founded by Swiss Federal Railways in 1918 in Zurich. The concept eventually grew to encompass all transportation and, in 1942, the Swiss Museum of Transport association was established. Swiss Federal Railways was joi ...

Aircraft Designers
An aircraft ( 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 the dynamic lift of an airfoil, or, in a few cases, direct downward thrust from its engines. Common examples of aircraft include airplanes, rotorcraft (including helicopters), airships (including blimps), gliders, paramotors, and hot air balloons. Part 1 (Definitions and Abbreviations) of Subchapter A of Chapter I of Title 14 of the U. S. Code of Federal Regulations states that aircraft "means a device that is used or intended to be used for flight in the air." 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, whereas unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
