Timeline Of Aviation - 18th Century
This is a list of aviation-related events during the 18th century (January 1, 1701 – December 31, 1800): 1700s–1770s *1709 **Portuguese Father Bartolomeu de Gusmão demonstrates a practical model of a hot-air balloon made of a paper envelope with burning material suspended below it to King John V of Portugal in the Ambassadors drawing room. Worried that it will set fire to the curtains, servants end its flight by dashing it to the ground. It is the first known demonstration of a practical lighter-than-air craft. *1716 ** Well thought-out glider-project of the Swedish scholar Emanuel Swedenborg. Basis for his construction are bird flight and the glider kite. *1738 **In his ''Hydrodynamica'' the Swiss scholar Daniel Bernoulli (1700–1782) formulates the principle of the conservation of energy for fluids (Bernoulli's principle), the relationship between pressure and velocity in a flow. *1746 **English military engineer Benjamin Robins (1707–1751) invented a whirling arm centr ...

Robert Brothers
Les Frères Robert were two French brothers. Anne-Jean Robert (1758–1820) and Nicolas-Louis Robert (1760–1828) were the engineers who built the world's first hydrogen balloon for professor Jacques Charles, which flew from central Paris on 27 August 1783. They went on to build the world's first manned hydrogen balloon, and on 1 December 1783 Nicolas-Louis accompanied Jacques Charles on a 2-hour, 5-minute flight. Their barometer and thermometer made it the first balloon flight to provide meteorological measurements of the atmosphere above the Earth's surface. The brothers subsequently experimented with an elongated elliptical shape for the hydrogen envelope in a balloon they attempted to power and steer by means of oars and umbrellas. In September 1784 the brothers flew 186 km from Paris to Beuvry, the world's first flight of more than 100 km. Career Background The Robert brothers were skilled engineers with a workshop at the ''Place des Victoires'' in Paris, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jacques Charles
Jacques Alexandre César Charles (12 November 1746 – 7 April 1823) was a French people, French inventor, scientist, mathematician, and balloonist. Charles wrote almost nothing about mathematics, and most of what has been credited to him was due to mistaking him with another Jacques Charles (sometimes called Charles the Geometer), also a member of the Paris Academy of Sciences, entering on 12 May 1785. Charles and the Robert brothers launched the world's first hydrogen-filled gas balloon August 27, 1783; then December 1, 1783, Charles and his co-pilot Robert brothers, Nicolas-Louis Robert ascended to a height of about 1,800 feet (550 m) in a piloted gas balloon. Their pioneering use of hydrogen for lift led to this type of gas balloon being named a ''Charlière'' (as opposed to the hot air balloon, hot-air Montgolfière). Charles's law, describing how gases tend to expand when heated, was formulated by Joseph Louis Gay-Lussac in 1802, but he credited it to unpublished work by Ch ...

Hydrogen Balloon
Hydrogen is a chemical element; it has symbol H and atomic number 1. It is the lightest and most abundant chemical element in the universe, constituting about 75% of all normal matter. Under standard conditions, hydrogen is a gas of diatomic molecules with the formula , called dihydrogen, or sometimes hydrogen gas, molecular hydrogen, or simply hydrogen. Dihydrogen is colorless, odorless, non-toxic, and highly combustible. Stars, including the Sun, mainly consist of hydrogen in a plasma state, while on Earth, hydrogen is found as the gas (dihydrogen) and in molecular forms, such as in water and organic compounds. The most common isotope of hydrogen (H) consists of one proton, one electron, and no neutrons. Hydrogen gas was first produced artificially in the 17th century by the reaction of acids with metals. Henry Cavendish, in 1766–1781, identified hydrogen gas as a distinct substance and discovered its property of producing water when burned; hence its name means 'wate ...

Lyon
Lyon (Franco-Provençal: ''Liyon'') is a city in France. It is located at the confluence of the rivers Rhône and Saône, to the northwest of the French Alps, southeast of Paris, north of Marseille, southwest of Geneva, Switzerland, northeast of Saint-Étienne. The City of Lyon is the List of communes in France with over 20,000 inhabitants, third-largest city in France with a population of 522,250 at the Jan. 2021 census within its small municipal territory of , but together with its suburbs and exurbs the Lyon Functional area (France), metropolitan area had a population of 2,308,818 that same year, the second largest in France. Lyon and 58 suburban municipalities have formed since 2015 the Lyon Metropolis, Metropolis of Lyon, a directly elected metropolitan authority now in charge of most urban issues, with a population of 1,424,069 in 2021. Lyon is the Prefectures in France, prefecture of the Auvergne-Rhône-Alpes Regions of France, region and seat of the Departmental co ...

Annonay
Annonay (; ) is a Communes of France, commune and largest city in the north of the Ardèche department in the Auvergne-Rhône-Alpes region of southeastern France. It is the most populous commune in the Ardèche department although it is not the capital which is the smaller town of Privas. Other communes in the Ardèche department are Aubenas, Guilherand-Granges, and Tournon-sur-Rhône. Geography The commune consists of the city of Annonay and the hamlets of Vissenty, Chatinais, and Boucieu. With residential development, these four entities have merged into one today. Further away is the hamlet of Toissieu. Annonay was built over several small hills at the confluence of the rivers Cance (Canse) and Deûme (Deôme). Annonay is a crossroads of trade routes: from the Rhône Valley to the region of Saint-Étienne (east-west) and from Lyon to south of the Massif Central (north-south). It is located south of Lyon, south-west of Saint-Rambert-d'Albon, and north-west of Saint-Vallier ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hot Air Balloon
A hot air balloon is a lighter-than-air aircraft consisting of a bag, called an envelope, which contains heated air. Suspended beneath is a gondola or wicker basket (in some long-distance or high-altitude balloons, a capsule), which carries passengers and a source of heat, in most cases an open flame caused by burning liquid propane. The heated air inside the envelope makes it buoyant, since it has a lower density than the colder air outside the envelope. As with all aircraft, hot air balloons cannot fly beyond the atmosphere. The envelope does not have to be sealed at the bottom, since the air inside the envelope is at about the same pressure as the surrounding air. In modern sport balloons the envelope is generally made from nylon fabric, and the inlet of the balloon (closest to the burner flame) is made from a fire-resistant material such as Nomex. Modern balloons have been made in many shapes, such as rocket ships and the shapes of various commercial products, thou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Montgolfier Brothers
The Montgolfier brothers – Joseph-Michel Montgolfier (; 26 August 1740 – 26 June 1810) and Jacques-Étienne Montgolfier (; 6 January 1745 – 2 August 1799) – were aviation pioneers, balloonists and paper manufacturers from the Communes of France, commune Annonay in Ardèche, France. They invented the ''Montgolfière''-style hot air balloon, globe aérostatique, which launched the first confirmed piloted ascent by humans in 1783, carrying Jacques-Étienne. Joseph-Michel also invented the self-acting hydraulic ram (1796) and Jacques-Étienne founded the first paper-making vocational school. Together, the brothers invented a process to manufacture Vellum#Paper vellum, transparent paper. Early years Joseph-Michel and Jacques-Étienne Montgolfier were born into a family of paper manufacturers. Their parents were Pierre Montgolfier (1700–1793) and Anne Duret (1701–1760), who had 16 children. Pierre Montgolfier established his eldest son, Raymond (1730–1772), as his succ ...
