Rodrig Goliescu
Rodrig Goliescu (1877 – 1942) was a Romanian inventor, engineer, and lieutenant of Polish descent. He designed and built the "Avioplan," the first airplane with a tubular fuselage. Life Early life Rodrig Goliescu was born in Dorohoi in 1877. His father was Polish who moved to Romania in 1873. In 1900, Rodrig Goliescu finished the artillery and engineer school and became a lieutenant, at the same time receiving Romanian citizenship. He served as an active officer and from 1906 he dedicated himself to research in the aeronautical field. Studying the flight of birds, he created various aeromodelling projects. Aviation career In 1909, he worked out several highly original principals regarding the flight of heavier-than-air machines. His ideas were materialized in the flying machine called the ''Goliescu Avioplan''. The most original aspect of the Avioplan was the shape of its fuselage, designed for minimum aerodynamic drag and acting as a tube fan, increasing the efficiency of the ...

Dorohoi
Dorohoi () is a city in Botoșani County, Romania, on the right bank of the river Jijia, which broadens into a lake on the north. History Dorohoi used to be a market for the timber and farm produce of the north Moldavian highlands; merchants from the neighboring states flocked to its great fair, held on the June 12. The settlement is first mentioned in documents from 1408, where a treaty was signed between Moldavian voievode, Alexandru cel Bun, and the King of Poland and Hungary. Dorohoi was bombed by the Russians during World War I. Dorohoi used to be the capital of Dorohoi County, but was degraded to a municipality when the Soviet Union occupied Bessarabia and Northern Bukovina in late June 1940. On July 1, 1940, units of the Romanian Army attacked local Jews in a pogrom. These military actions against the Jews were not endorsed by the Romanian Government. When the conspiracy against the Jews was discovered by the military command, troops were sent to end the abuse. Geogr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spiru Haret
Spiru C. Haret (; 15 February 1851 – 17 December 1912) was a Romanian mathematician, astronomer, and politician. He made a fundamental contribution to the ''n''-body problem in celestial mechanics by proving that using a third degree approximation for the disturbing forces implies instability of the major axes of the orbits, and by introducing the concept of ''secular perturbations'' in relation to this. As a politician, during his three terms as Minister of Education, Haret ran deep reforms, building the modern Romanian education system. He was made a full member of the Romanian Academy in 1892. He also founded the Bucharest Observatory, appointing as its first director. The crater Haret on the Moon is named after him. Life Haret was born in Iași, Moldavia, to Constantin and Smaranda Haret, who were of Armenian origin. His baptismal record listed his name as Spiridon Haret. He started his studies in Dorohoi Iași, and in 1862 moved to Saint Sava High School in Bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eurocopter AS365 Dauphin
The Eurocopter (now Airbus Helicopters) AS365 Dauphin (''Dolphin''), also formerly known as the Aérospatiale SA 365 Dauphin 2, is a medium-weight multipurpose twin-engine helicopter produced by Airbus Helicopters. It was originally developed and manufactured by French firm Aérospatiale, which was merged into the multinational Eurocopter company during the 1990s. Since entering production in 1975, the type has been in continuous production for more than 40 years. The intended successor to the Dauphin is the Airbus Helicopters H160, which entered operational service in 2021. The Dauphin 2 shares many similarities with the Aérospatiale SA 360, a commercially unsuccessful single-engine helicopter; however the twin-engine Dauphin 2 did meet with customer demand and has been operated by a wide variety of civil and military operators. Since the type's introduction in the 1970s, several major variations and specialised versions of the Dauphin 2 have been developed and entered prod ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stipa-Caproni
The Stipa-Caproni, also known as the Caproni Stipa, was an experimental Italian aircraft designed in 1932 by Luigi Stipa (1900–1992) and built by Caproni. It featured a hollow, barrel-shaped fuselage with the engine and propeller completely enclosed by the fuselage—in essence, the whole fuselage was a single ducted fan. Although the ''Regia Aeronautica'' (Italian Royal Air Force) was not interested in pursuing development of the Stipa-Caproni, its design influenced the development of jet propulsion. Stipa's design Stipa’s basic idea, which he called the " intubed propeller", was to mount the engine and propeller inside a fuselage that itself formed a tapered duct, or venturi tube, and compressed the propeller's airflow and the engine exhaust before it exited the duct at the trailing edge of the aircraft, essentially applying Bernoulli's principle of fluid movements to make the aircraft's propeller more efficient. This is a similar principle as is used in turbofan engines ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Luigi Stipa
Luigi Stipa (30 November 1900 – 9 January 1992) was an Italian aeronautical, hydraulic, and civil engineer and aircraft designer who invented the "intubed propeller" for aircraft, a concept that some aviation historians view as the predecessor of the turbofan engine. Early life and career Stipa was born in Appignano del Tronto, Italy in 30 November 1900. He left school to serve in the Italian Army's Bersaglieri Corps during World War I. After the war, he earned academic degrees in aeronautical engineering, hydraulic engineering and civil engineering. He went to work for the Italian Air Ministry, where he rose to the position of general inspector of the Engineering Division of the ''Regia Aeronautica'' (Italian Royal Air Force). Intubed propeller In the 1920s, Stipa applied his study of hydraulic engineering to develop a theory of how to make aircraft more efficient as they traveled through the air. Noting that in fluid dynamics—in accordance with Bernoulli's principle ... [...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 ...

Paris
Paris () is the capital and most populous city of France, with an estimated population of 2,165,423 residents in 2019 in an area of more than 105 km² (41 sq mi), making it the 30th most densely populated city in the world in 2020. Since the 17th century, Paris has been one of the world's major centres of finance, diplomacy, commerce, fashion, gastronomy, and science. For its leading role in the arts and sciences, as well as its very early system of street lighting, in the 19th century it became known as "the City of Light". Like London, prior to the Second World War, it was also sometimes called the capital of the world. The City of Paris is the centre of the Île-de-France region, or Paris Region, with an estimated population of 12,262,544 in 2019, or about 19% of the population of France, making the region France's primate city.

Juvisy
Juvisy-sur-Orge (, literally ''Juvisy on Orge'') is a commune in the Essonne department in Île-de-France in northern France. It is located 18 km south-east of Paris, a few kilometres south of Orly Airport. The site of the town has been occupied from ancient times; it is noted in Julius Caesar's book about the Gallic Wars. Centuries later, it became an important place under the French monarchy, as a royal hotel. It would also be used as a post relay, the first one on the road to Fontainebleau. It became a major road and railway junction in the 1840s after its railway station was built in 1840, and after 1893 was the first city surrounding Paris with a bridge crossing the river Seine. Most of the city was destroyed in April 1944 by an Allied bombing as the city was the only one surrounding Paris that had such a big railway station and had railway lines going to most of France's major cities. It was then rebuilt between 1945 and the 1970s. The city is today known for Gare d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aéro-Club De France
The Aéro-Club de France () was founded as the Aéro-Club on 20 October 1898 as a society 'to encourage aerial locomotion' by Ernest Archdeacon, Léon Serpollet, Henri de la Valette, Jules Verne and his wife, André Michelin, Albert de Dion, Alberto Santos-Dumont, Henri Deutsch de la Meurthe, and Henry de La Vaulx. On 20 April 1909, its name was changed to ''Aéro-Club de France''. The Aéro-Club de France originally set many of the regulations that controlled aviation in France. From its formation it also set the rules that have marked some of the 'firsts' in aviation, such as the first closed-circuit flight of over 1 km and the first helicopter flight, and has organised competitions including: * the Prix Deutsch de la Meurthe, a challenge for dirigibles from 1901 * the Gordon Bennett Cup for fixed-wing aircraft in 1909 The club published the journal ''L'Aérophile'' from 1898 to 1947, and since 1997 publishes the magazine ''Aérofrance''.
