Ellehammer Semi-biplane
__NOTOC__ The Ellehammer Semi-biplane was a pioneering aircraft flown in Denmark in 1906. Jacob Ellehammer built the aircraft based on his monoplane design of the previous year. Like that aircraft, it featured a large, triangular wing, with a motor (of Ellehammer's own design and construction) mounted beneath it. The pilot sat on a seat that was suspended like a pendulum A pendulum is a weight suspended from a pivot so that it can swing freely. When a pendulum is displaced sideways from its resting, equilibrium position, it is subject to a restoring force due to gravity that will accelerate it back toward the ..., allowing him to shift his weight to control the aircraft, similar in concept (if not execution) to the control of a modern hang-glider. Unlike his monoplane, however, the semi-biplane's main wing formed a constant, unbroken span. Additionally, it was fitted with an upper wing of the same triangular shape, which connected to the main wing at its three corners and t ...

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".

Danmarks Flymuseum
The Danmarks Flymuseum is a museum located at Stauning Vestjylland Airport, Stauning Airport in Stauning (village), Stauning, Denmark. It has a collection of around 70 aircraft from the period 1911 until 2000. Around 60 aircraft are on display. The collection includes gliders, fighter planes and helicopters. Many are still airworthy. The collection is considered part of Military museums in Denmark, Denmark's Air Force Museum as it hosts the collection of the Royal Danish Air Force. The museum has a restoration department which restores and maintains aircraft. Stauning Airport is also home of a yearly vintage aircraft rally. Denmark.

Jacob Ellehammer
Jacob Christian Hansen-Ellehammer (14 June 1871 – 20 May 1946) was a Danish watchmaker and inventor born in Bakkebølle, Denmark. He is remembered chiefly for his contributions to powered flight. Following the end of his apprenticeship as a watchmaker, he moved to Copenhagen where he worked as an electronics mechanic before establishing his own company in 1898. In the beginning he produced cigarette machines, beverage machines and other electronic machinery. In 1904 he produced his first motorcycle, the Elleham motorcycle. The Elleham motorcycle is of step-tru type with the engine situated beneath the seating, thus predating the Vespa scooter by 40 years. In 1903–1904 Jacob Hansen-Ellehammer used his experience constructing motorcycles fitted with single-cylinder Peugeot Frères engines to build the world's first air-cooled radial engine, a three-cylinder engine by utilizing Peugeot Frères cylinders and heads in a home-cast engine block. The initial engine soon proved too ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1906 In Aviation
This is a list of aviation-related events from 1906: Events January–December *17 January – The Zeppelin '' LZ2'' makes its first flight, which ends in a forced landing. *18 January – The Zeppelin ''LZ2'' is destroyed in high winds. *27 February – American aviation pioneer Samuel Pierpont Langley dies at Aiken, South Carolina. *5 March – Romanian inventor Traian Vuia begins testing his ''Vuia 1'' at Montesson, France, by driving it as an automobile without its wings mounted. It is a high-wing monoplane powered by a carbonic acid gas engine, and is first aircraft with pneumatic tires. *18 March – At Montesson, Traian Vuia achieves several short hops in his ''Vuia 1'', traveling about 12 meters (39 feet) at an altitude of about 1 meter (3 feet). He flies four more times; one flight travels some 20 meters (66 feet) at an altitude of 1 meter (3 feet), and the longest flight is 24 meters (79 feet), the first manned flights ...

Pendulum
A pendulum is a weight suspended from a pivot so that it can swing freely. When a pendulum is displaced sideways from its resting, equilibrium position, it is subject to a restoring force due to gravity that will accelerate it back toward the equilibrium position. When released, the restoring force acting on the pendulum's mass causes it to oscillate about the equilibrium position, swinging back and forth. The time for one complete cycle, a left swing and a right swing, is called the period. The period depends on the length of the pendulum and also to a slight degree on the amplitude, the width of the pendulum's swing. From the first scientific investigations of the pendulum around 1602 by Galileo Galilei, the regular motion of pendulums was used for timekeeping and was the world's most accurate timekeeping technology until the 1930s. The pendulum clock invented by Christiaan Huygens in 1658 became the world's standard timekeeper, used in homes and offices for 270 years, and ac ...

Citroën 2CV
The Citroën 2CV (french: link=no, deux chevaux(-vapeur), , lit. "two steam horse(power)s", meaning "two ''taxable'' horsepower") is an air-cooled front-engine, front-wheel-drive, economy family car, introduced at the 1948 Paris Mondial de l'Automobile, and manufactured by Citroën for model years 1948–1990. Conceived by Citroën Vice-President Pierre Boulanger to help motorise the large number of farmers still using horses and carts in 1930s France, the 2CV has a combination of innovative engineering and straightforward, utilitarian bodywork — at first with extra thin panels, reinforced by ''corrugating'' the metal. The 2CV featured overall low cost of ownership, simplicity of maintenance, an easily serviced air-cooled engine (originally offering 9 hp), and minimal fuel consumption. In addition, it had literally been designed to cross a freshly ploughed field, because of the great lack of paved roads in France then; with a long-travel suspension system, that con ...
