Grigore Brișcu
Grigore Brişcu (1884 in Bârlad – 1965 in Bucharest) was a Romanian engineer and inventor.Petru Ciontu, ''Inventatori români'', p.46. Editura Osim, 2000 Inventor of the helicopter 1909 Brişcu was the first engineer to begin experimenting with the cyclic variation of rotor blade pitch to ensure horizontal flight and stability in helicopters. He invented a prototype "air-carriage" with all the features of a helicopter-like flying-machine: horizontal, vertical and lateral movement and fixed-point landing. It was equipped with two coaxial propellers rotating in opposite directions. This was flown experimentally by the French aviator Paul Cornu, who built a prototype with an Antoinett engine.

Bârlad
Bârlad () is a city in Vaslui County, Romania. It lies on the banks of the river Bârlad, which waters the high plains of Western Moldavia. At Bârlad the railway from Iași diverges, one branch skirting the river Siret, the other skirting the Prut; both reunite at Galați. Along with a maze of narrow and winding streets, Bârlad features several notable modern buildings, including the hospital administered by the Saint Spiridion Foundation of Iași. In the vicinity of the city are the ruins of a Roman camp. The city is the birthplace of Romanian ''Domnitor'' (Ruler) and diplomat Alexandru Ioan Cuza. Etymology Scholars continue to debate the origin of the city's name. The Hypatian Codex mentions a market town called ''Berlad'', and some historians, influenced by a document Bogdan Petriceicu Hasdeu published in the 19th century, have tried to link this town and its inhabitants (variously considered Romanians, East Slavs or an amalgam) with the Moldavian Bârlad.

Antoinette (manufacturer)
Antoinette was a French manufacturer of light petrol engines. Antoinette also became a pioneer-era builder of aeroplanes before World War I, most notably the record-breaking monoplanes flown by Hubert Latham and René Labouchère. Based in Puteaux, the Antoinette concern was in operation between 1903 and 1912. The company operated a flying school at Chalons for which it built one of the earliest flight simulators. Private engine-building venture Antoinette began as a private venture led by the engineer Léon Levavasseur and financed by Jules Gastambide, who owned an electricity generating station in Algeria. While on holiday with Gastambide and his family in 1902, Levavasseur expressed his interest in the emerging field of aviation and proposed the development of light, powerful engines for use in aircraft. Levavasseur then suggested to Gastambide's daughter, Antoinette, that the engines should be named after her. Gastambide financed the venture. Levavasseur patented th ...

People From Bârlad
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of ...

Aviation Pioneers
Aviation pioneers are people directly and indirectly responsible for the advancement of flight, including people who worked to achieve manned flight before the invention of aircraft, as well as others who achieved significant "firsts" in aviation after heavier-than-air flight became routine. Pioneers of aviation have contributed to the development of aeronautics in one or more ways: through science and theory, theoretical or applied design, by constructing models or experimental prototypes, the mass production of aircraft for commercial and government request, achievements in flight, and providing financial resources and publicity to expand the field of aviation. Table key Pioneer type * Science: Contributions to aerodynamic theory, aviation principles, discoveries advancing aircraft development, etc. * Design: Original or derivative ideas or drawings for conceptual/experimental/practical methods of air travel * Construction: Building prototypes/experimental/practical aircraft * ...

Aviation Inventors
Aviation includes the activities surrounding mechanical flight and the aircraft industry. ''Aircraft'' includes fixed-wing and rotary-wing types, morphable wings, wing-less lifting bodies, as well as lighter-than-air craft such as hot air balloons and airships. Aviation began in the 18th century with the development of the hot air balloon, an apparatus capable of atmospheric displacement through buoyancy. Some of the most significant advancements in aviation technology came with the controlled gliding flying of Otto Lilienthal in 1896; then a large step in significance came with the construction of the first powered airplane by the Wright brothers in the early 1900s. Since that time, aviation has been technologically revolutionized by the introduction of the jet which permitted a major form of transport throughout the world. Etymology The word ''aviation'' was coined by the French writer and former naval officer Gabriel La Landelle in 1863. He derived the term from the v ...

Rotary Engine
The rotary engine is an early type of internal combustion engine, usually designed with an odd number of cylinders per row in a radial configuration. The engine's crankshaft remained stationary in operation, while the entire crankcase and its attached cylinders rotated around it as a unit. Its main application was in aviation, although it also saw use in a few early motorcycles and automobiles. This type of engine was widely used as an alternative to conventional inline engines (straight or V) during World War I and the years immediately preceding that conflict. It has been described as "a very efficient solution to the problems of power output, weight, and reliability". By the early 1920s, the inherent limitations of this type of engine had rendered it obsolete. Description Distinction between "rotary" and "radial" engines A rotary engine is essentially a standard Otto cycle engine, with cylinders arranged radially around a central crankshaft just like a conventional ra ...

Paul Cornu
Paul Cornu (; June 15, 1881 – 6 June 1944) was a French engineer. Life Paul Cornu, of Romanian origins, was born in Glos la Ferrière, France and was one of thirteen children. At a young age, he helped his father in his transports company. He made history by designing the world's first successful manned rotary wing aircraft. Cornu first built an unmanned experimental design powered by a 2 hp Buchet engine. His manned helicopter was powered by a Antoinette engine. He piloted this construction himself at Normandy, France on November 13, 1907. Previously, a French helicopter, the Breguet-Richet Gyroplane I, had managed to lift off under its own power, but it had been held in position by men standing on the ground. Cornu's performance was a considerable progress because his aircraft flew without additional support and lifted Cornu about 30 cm (1 ft) for 20 seconds. Unfortunately this early helicopter was scarcely maneuverable and had only a few additional flig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bucharest
Bucharest ( , ; ro, București ) is the capital and largest city of Romania, as well as its cultural, industrial, and financial centre. It is located in the southeast of the country, on the banks of the Dâmbovița River, less than north of the Danube River and the Bulgarian border. Bucharest was first mentioned in documents in 1459. The city became the capital of Romania in 1862 and is the centre of Romanian media, culture, and art. Its architecture is a mix of historical (mostly Eclectic, but also Neoclassical and Art Nouveau), interbellum ( Bauhaus, Art Deco and Romanian Revival architecture), socialist era, and modern. In the period between the two World Wars, the city's elegant architecture and the sophistication of its elite earned Bucharest the nickname of 'Paris of the East' ( ro, Parisul Estului) or 'Little Paris' ( ro, Micul Paris). Although buildings and districts in the historic city centre were heavily damaged or destroyed by war, earthquakes, and even Nic ...

Propeller
A propeller (colloquially often called a screw if on a ship or an airscrew if on an aircraft) is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral which, when rotated, exerts linear thrust upon a working fluid such as water or air. Propellers are used to pump fluid through a pipe or duct, or to create thrust to propel a boat through water or an aircraft through air. The blades are specially shaped so that their rotational motion through the fluid causes a pressure difference between the two surfaces of the blade by Bernoulli's principle which exerts force on the fluid. Most marine propellers are screw propellers with helical blades rotating on a propeller shaft (ship), propeller shaft with an approximately horizontal axis. History Early developments The principle employed in using a screw propeller is derived from sculling. In sculling, a single blade is moved through an arc, from side to side taking care to keep presenting the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helicopter
A helicopter is a type of rotorcraft in which lift and thrust are supplied by horizontally spinning rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forward, backward and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of STOL (Short TakeOff and Landing) or STOVL (Short TakeOff and Vertical Landing) aircraft cannot perform without a runway. In 1942, the Sikorsky R-4 became the first helicopter to reach full-scale production.Munson 1968.Hirschberg, Michael J. and David K. Dailey"Sikorsky". ''US and Russian Helicopter Development in the 20th Century'', American Helicopter Society, International. 7 July 2000. Although most earlier designs used more than one main rotor, the configuration of a single main rotor accompanied by a vertical anti-torque tail rotor (i.e. unicopter, not to be confused with the single-blade monocopter) has become the most comm ...
