Coandă-1910
The Coandă-1910, designed by Romanian inventor Henri Coandă, was an unconventional sesquiplane aircraft powered by a ducted fan. Called the "turbo-propulseur" by Coandă, its experimental engine consisted of a conventional piston engine driving a multi-bladed centrifugal blower which exhausted into a duct. The unusual aircraft attracted attention at the Second International Aeronautical Exhibition in Paris in October 1910, being the only exhibit without a propeller, but the aircraft was not displayed afterwards, and it fell from public awareness. Coandă used a similar turbo-propulseur to drive a snow sledge, but he did not develop it further for aircraft. Decades later, after the practical demonstration of motorjets and turbojets, Coandă began to tell various conflicting stories about how his early experiments were precursors to the jet, even that his turbo-propulseur was the first motorjet engine with fuel combustion in the airstream. He also claimed to have made a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henri Coandă
Henri Marie Coandă (; 7 June 1886 – 25 November 1972)''Flight'' 1973 was a Romanian inventor, aerodynamics pioneer, and builder of an experimental aircraft, the Coandă-1910, which never flew. He invented a great number of devices, designed a "flying saucer" and discovered the Coandă effect of fluid dynamics. In the 1950s, Coandă inflated his importance in aviation history, describing falsely how he had invented the air-breathing jet engine and incorporated that design into the Coandă-1910 aircraft. However, his ducted engine design, the "turbo-propulseur", was described in its patent as working the same way with either water or air running through. Life Early life Born in Bucharest, Coandă was the second child of a large family. His father was General Constantin Coandă, a mathematics professor at the National School of Bridges and Roads. His mother, Aida Danet, was the daughter of French physician Gustave Danet, and was born in Brittany. Coandă recalled later in ...

Counter-rotating Propellers
Counter-rotating propellers (CRP) are propellers which turn in opposite directions to each other. They are used on some twin- and multi-engine propeller-driven aircraft. The propellers on most conventional twin-engined aircraft turn clockwise (as viewed from behind the engine). Counter-rotating propellers generally turn clockwise on the left engine and counterclockwise on the right. The advantage of such designs is that counter-rotating propellers balance the effects of torque and P-factor, meaning that such aircraft do not have a critical engine in the case of engine failure. Drawbacks of counter-rotating propellers come from the fact that, in order to reverse the rotation of one propeller, either one propeller must have an additional reversing gearbox, or the engines themselves must be adapted to turn in opposite directions. (Meaning that there are essentially two engine designs, one with left-turning and the other with right-turning parts, which complicates manufacture a ...

Octave Chanute
Octave Chanute (February 18, 1832 – November 23, 1910) was a French-American civil engineer and aviation pioneer. He advised and publicized many aviation enthusiasts, including the Wright brothers. At his death, he was hailed as the father of aviation and the initial concepts of the heavier-than-air flying machine. Early life Octave Chanute was born in Paris to Elise and Joseph Chanut, professor at the Collège de France. Octave and Joseph emigrated to the United States of America in 1838, when Joseph was named Vice President of Jefferson College in Louisiana. Octave attended private schools in New York. He added the "e" to his last name in his adult life. In 1857, he married Anne Riddell James, with whom he had a son and three daughters. Career Railroad civil engineer Chanute began his training as a civil engineer in 1848. He was widely considered brilliant and innovative in the engineering profession.

Otto Lilienthal
Karl Wilhelm Otto Lilienthal (23 May 1848 – 10 August 1896) was a German pioneer of aviation who became known as the "flying man". He was the first person to make well-documented, repeated, successful flights with gliders, therefore making the idea of heavier-than-air aircraft a reality. Newspapers and magazines published photographs of Lilienthal gliding, favourably influencing public and scientific opinion about the possibility of flying machines becoming practical. Lilienthal's work led to his developing the concept of the modern wing. His flight attempts in 1891 are seen as the beginning of human flight and the " Lilienthal Normalsegelapparat" is considered the first airplane in series production, making the ''Maschinenfabrik Otto Lilienthal'' in Berlin the first airplane production company in the world. He has been referred to as the "father of aviation" and "father of flight". On 9 August 1896, Lilienthal’s glider stalled and he was unable to regain control. Fallin ...

A fervent supporter of ''Weltpolitik'', Bülow devoted his chancellorship to transforming Germany into a global power. Despite presiding over sustained economic growth and major technological advancements within his country, his government's foreign policy did much to antagonize France and Great Britain thereby contributing significantly to the outbreak of the World War I, a conflict that resulted in the fall of the German Empire. Born into a prominent family of Danish-German aristocrats, Bülow entered the German foreign service after his father, Bernhard Ernst von Bülow, was appointed foreign secretary in Otto von Bismarck's government.

Degree (angle)
A degree (in full, a degree of arc, arc degree, or arcdegree), usually denoted by ° (the degree symbol), is a measurement of a plane (mathematics), plane angle in which one Turn (geometry), full rotation is 360 degrees. It is not an SI unit—the SI unit of angular measure is the radian—but it is mentioned in the SI Brochure, SI brochure as an Non-SI units mentioned in the SI, accepted unit. Because a full rotation equals 2 radians, one degree is equivalent to radians. History The original motivation for choosing the degree as a unit of rotations and angles is unknown. One theory states that it is related to the fact that 360 is approximately the number of days in a year. Ancient astronomers noticed that the sun, which follows through the ecliptic path over the course of the year, seems to advance in its path by approximately one degree each day. Some ancient calendars, such as the Iranian calendar, Persian calendar and the Babylonian calendar, used 360 days for a year. ...
