Félix Du Temple De La Croix
Félix du Temple de la Croix (18 July 1823 – 3 November 1890) (usually simply called Félix du Temple) was a French naval officer and an inventor, born into an ancient Normandy, Norman family. He developed some of the Early flying machines, first flying machines and is credited with the first successful flight of a powered aircraft of any sort, a powered model plane, in 1857 and is sometimes credited with the first manned powered flight in history aboard his Du Temple Monoplane, Monoplane in 1874. He was a contemporary of Jean-Marie Le Bris. Military life Félix du Temple entered the French Navy Academy (École Navale) in 1838. He participated in most of the conflicts during the Second French Empire, especially the Crimean War, the French intervention in Italy against Austria, and the Second French intervention in Mexico, French intervention in Mexico. At the age of 41, he returned to France, became a captain (Capitaine de Frégate), and joined the Loire Army (Armée de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dihedral (aircraft)
Dihedral angle is the upward angle from horizontal of the wings or tailplane of a fixed-wing aircraft. "Anhedral angle" is the name given to negative dihedral angle, that is, when there is a ''downward'' angle from horizontal of the wings or tailplane of a fixed-wing aircraft. Dihedral angle has a strong influence on dihedral effect, which is named after it. Dihedral effect is the amount of roll moment produced in proportion to the amount of sideslip. Dihedral effect is a critical factor in the stability of an aircraft about the roll axis (the spiral mode). It is also pertinent to the nature of an aircraft's Dutch roll oscillation and to maneuverability about the roll axis. Longitudinal dihedral is a comparatively obscure term related to the pitch axis of an airplane. It is the angle between the zero-lift axis of the wing and the zero-lift axis of the horizontal tail. Longitudinal dihedral can influence the nature of controllability about the pitch axis and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Du Temple Boiler
Three-drum boilers are a class of water-tube boiler used to generate steam, typically to power ships. They are compact and of high evaporative power, factors that encourage this use. Other boiler designs may be more efficient, although bulkier, and so the three-drum pattern was rare as a land-based stationary boiler. The fundamental characteristic of the "three-drum" design is the arrangement of a steam drum above two water drums, in a triangular layout. Water tubes fill in the two sides of this triangle between the drums, and the furnace is in the centre. The whole assembly is then enclosed in a casing, leading to the exhaust flue. Firing can be by either coal or oil. Many coal-fired boilers used multiple firedoors and teams of stokers, often from both ends. Development Development of the three-drum boiler began in the late 19th century, with the demand from naval ships that required high power and a compact boiler. The move to water-tube boilers had already begun, wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Exposition Universelle (1878)
The 1878 Universal Exposition (, ), also known as the 1878 Paris Exposition, 1878 World Fair, or 1878 World Expo, was a world's fair held in Paris, French Third Republic, France, from 1 May to 10 November 1878, to celebrate the recovery of France after the 1870–71 Franco-Prussian War. It was the List of world expositions, third of ten major expositions held in the city between 1855 and 1937. Construction The buildings and the fairgrounds were somewhat unfinished on opening day, as political complications had prevented the French government from paying much attention to the exhibition until six months before it was due to open. However, efforts made in April were prodigious, and by 1 June, a month after the formal opening, the exhibition was finally completed. This exposition was on a far larger scale than any previously held anywhere in the world. It covered over , the main building in the Champ de Mars and the hill of Chaillot, occupying . The Gare du Champ de Mars was rebu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wingspan
The wingspan (or just span) of a bird or an airplane is the distance from one wingtip to the opposite wingtip. For example, the Boeing 777–200 has a wingspan of , and a wandering albatross (''Diomedea exulans'') caught in 1965 had a wingspan of , the official record for a living bird. The term wingspan, more technically 'extent' , is also used for other winged animals such as pterosaurs, bats, insects, etc., and other aircraft such as ornithopters. In humans, the term wingspan also refers to the arm span, which is the distance between the length from the end of an individual's arm (measured at the fingertips) to the individual's fingertips on the other arm when raised parallel to the ground at shoulder height. Wingspan of aircraft The wingspan of an aircraft is always measured in a straight line, from wingtip to wingtip, regardless of wing shape or sweep. Implications for aircraft design and animal evolution The lift from wings is proportional to their area, so the h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
France
France, officially the French Republic, is a country located primarily in Western Europe. Overseas France, Its overseas regions and territories include French Guiana in South America, Saint Pierre and Miquelon in the Atlantic Ocean#North Atlantic, North Atlantic, the French West Indies, and List of islands of France, many islands in Oceania and the Indian Ocean, giving it Exclusive economic zone of France, one of the largest discontiguous exclusive economic zones in the world. Metropolitan France shares borders with Belgium and Luxembourg to the north; Germany to the northeast; Switzerland to the east; Italy and Monaco to the southeast; Andorra and Spain to the south; and a maritime border with the United Kingdom to the northwest. Its metropolitan area extends from the Rhine to the Atlantic Ocean and from the Mediterranean Sea to the English Channel and the North Sea.

Brest, France
Brest (; ) is a port, port city in the Finistère department, Brittany (administrative region), Brittany. Located in a sheltered bay not far from the western tip of a peninsula and the western extremity of metropolitan France, Brest is an important harbour and the second largest French military port after Toulon. The city is located on the western edge of continental France. With 139,456 inhabitants (2020), Brest forms Lower Brittany, Western Brittany's largest functional area (France), metropolitan area (with a population of 370,000 in total), ranking third behind only Nantes and Rennes in the whole of historic Brittany, and the List of communes in France with over 20,000 inhabitants, 25th most populous city in France (2019); moreover, Brest provides services to the one million inhabitants of Western Brittany. Although Brest is by far the largest city in Finistère, the ''Prefectures in France, préfecture'' (administrative seat) of the department is in the much smaller town of ...

Aluminium
Aluminium (or aluminum in North American English) is a chemical element; it has chemical symbol, symbol Al and atomic number 13. It has a density lower than that of other common metals, about one-third that of steel. Aluminium has a great affinity towards oxygen, passivation (chemistry), forming a protective layer of aluminium oxide, oxide on the surface when exposed to air. It visually resembles silver, both in its color and in its great ability to reflect light. It is soft, magnetism, nonmagnetic, and ductility, ductile. It has one stable isotope, 27Al, which is highly abundant, making aluminium the abundance of the chemical elements, 12th-most abundant element in the universe. The radioactive decay, radioactivity of aluminium-26, 26Al leads to it being used in radiometric dating. Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al3+ ...

Monoplane (1874)
The du Temple Monoplane was a steam-powered aircraft made of aluminium, built in Brest, France, by naval officer Félix du Temple in 1874. It had a wingspan of 13 m (43 ft) and weighed 80 kg (180 lb) without the pilot. Several trials were made with the aircraft, and it is generally recognized that it achieved lift-off. It was described by Dollfus as a "short hop or leap"; ''Flight International'' described the plane as having "staggered briefly into the air" – (from a combination of its own power and running down an inclined ramp) It glided for a short time and returned safely to the ground, making it the first successful powered flight in history, though not the first self-powered one. It was displayed at the 1878 ''Exposition Universelle'' ("World Fair") in Paris. Steam engine The aircraft used a very compact, high-speed circulation steam engine for which Félix du Temple applied for a patent on 28 April 1876. The engine used very small pipes packed ...
