L'Intrépide
''L'Intrépide'' ("The Intrepid") was a hydrogen balloon of the ''Compagnie d'Aérostiers'' (French Aerostatic Corps) and is the oldest preserved manned aircraft in Europe.Information plaque displayed in the ''Heeresgeschichtliches Museum'': "Da es sich hierbei um das älteste noch bekannte Luftfahrzeug Europas handelte, mußte nicht zuletzt aus Rücksicht auf konservatorische Bedingungen die originale Ballonhülle entsprechend gesondert untergebracht werden." ''L'Intrépide'' was the larger of two observation balloons, the other being '' Hercule'' ("Hercules"), issued to the Aerostatic Corps in June 1795, twelve years after the pioneering hydrogen balloon flights of Professor Jacques Charles and the Robert brothers in Paris. These balloons were used by the Corps's first company attached to General Jourdan's Army of Sambre-et-Meuse in 1796. When that army was defeated by Austrian forces at the Battle of Würzburg on 3 September 1796, the balloon was captured and taken to Vien ...

Compagnie D'Aérostiers
The French Aerostatic Corps or Company of Aeronauts (french: compagnie d'aérostiers) was the world's first balloon unit,Jeremy Beadle and Ian Harrison, ''First, Lasts & Onlys: Military'', p. 42 founded in 1794 to use balloons, primarily for reconnaissance. Experimentation Numerous suggestions had been made for the use of balloons during the French Revolutionary Wars, and in 1793 the Committee of Public Safety began testing their potential. Initial tests of airship designs proved unsatisfactory.F. Stansbury Haydon, ''Military Ballooning During the Early Civil War'', pp.5-15 However, experiments conducted near the Tuileries from September to October 1793 to produce the required hydrogen without the use of sulphuric acid, which was in short supply, were successful, producing more than 20 cubic metres.Charles Coulston Gillispie, ''Science and Polity in France: The Revolutionary and Napoleonic Years'', pp. 372-373 As a result, the Committee determined to use this technique to floa ...

Observation Balloon
An observation balloon is a type of balloon that is employed as an aerial platform for intelligence gathering and artillery spotting. Use of observation balloons began during the French Revolutionary Wars, reaching their zenith during World War I, and they continue in limited use today. Synonyms include espionage balloon, reconnaissance balloon, or surveillance balloon. Historically, observation balloons were filled with hydrogen. The balloons were fabric envelopes filled with hydrogen gas, whose flammable nature led to the destruction of hundreds of balloons on both sides. Observers manning these observation balloons frequently had to use a parachute to evacuate their balloon when it came under attack. To avoid the potentially flammable consequences of hydrogen, observation balloons after World War I were often filled with non-flammable helium. Typically, balloons were tethered to a steel cable attached to a winch that reeled the gasbag to its desired height (usually 1,000-1,5 ...

Hydrogen Balloon
Hydrogen is the chemical element with the symbol H and atomic number 1. Hydrogen is the lightest element. At standard conditions hydrogen is a gas of diatomic molecules having the formula . It is colorless, odorless, tasteless, non-toxic, and highly combustible. Hydrogen is the most abundant chemical substance in the universe, constituting roughly 75% of all normal matter.However, most of the universe's mass is not in the form of baryons or chemical elements. See dark matter and dark energy. Stars such as the Sun are mainly composed of hydrogen in the plasma state. Most of the hydrogen on Earth exists in molecular forms such as water and organic compounds. For the most common isotope of hydrogen (symbol 1H) each atom has one proton, one electron, and no neutrons. In the early universe, the formation of protons, the nuclei of hydrogen, occurred during the first second after the Big Bang. The emergence of neutral hydrogen atoms throughout the universe occurred about 370,000 yea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jacques Charles
Jacques Alexandre César Charles (November 12, 1746 – April 7, 1823) was a 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, also a member of the Paris Academy of Sciences, entering on May 12, 1785. He was sometimes called Charles the Geometer. Charles and the Robert brothers launched the world's first unmanned hydrogen-filled gas balloon in August 1783; then in December 1783, Charles and his co-pilot Nicolas-Louis Robert ascended to a height of about 1,800 feet (550 m) in a manned gas balloon. Their pioneering use of hydrogen for lift led to this type of balloon being named a ''Charlière'' (as opposed to a Montgolfière which used hot air). 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 Jacques Charles. Charles ...

Robert Brothers
Les Frères Robert were two French brothers. Anne-Jean Robert (1758–1820) and Nicolas-Louis Robert (1760–1820) 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, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jean-Baptiste Jourdan
Jean-Baptiste Jourdan, 1st Count Jourdan (29 April 1762 – 23 November 1833), was a French military commander who served during the French Revolutionary Wars and the Napoleonic Wars. He was made a Marshal of the Empire by Emperor Napoleon I in 1804. He was also a Jacobin politician during the Directory phase of the French Revolution, serving as member of the Council of Five Hundred between 1797 and 1799. One of the most successful commanders of the French Revolutionary Army, Jourdan is best remembered in the Revolution for leading the French to a decisive victory over the First Coalition at the Battle of Fleurus, during the Flanders campaign. Under the Empire he was rewarded by Napoleon with the title of Marshal and continued to hold military assignments, but suffered a major defeat at the Battle of Vitoria, which resulted in the Empire's permanent loss of Spain. In 1815 he became reconciled with the Bourbon Restoration, and later supported the July Revolution and served in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Army Of Sambre-et-Meuse
The Army of Sambre and Meuse (french: Armée de Sambre-et-Meuse) was one of the armies of the French Revolution. It was formed on 29 June 1794 by combining the Army of the Ardennes, the left wing of the Army of the Moselle and the right wing of the Army of the North. Its maximum paper strength (in 1794) was approximately 120,000. After an inconclusive campaign in 1795, the French planned a co-ordinated offensive in 1796 using Jean-Baptiste Jourdan's Army of the Sambre et Meuse and the Army of the Rhine and Moselle commanded by his superior, Jean Victor Moreau. The first part of the operation called for Jourdan to cross the Rhine north of Mannheim and divert the Austrians while the Army of the Moselle crossed the southern Rhine at Kehl and Huningen. This was successful and, by July 1796, a series of victories forced the Austrians, commanded by Archduke Charles to retreat into the German states. By late July, most of the southern German states had been coerced into an armisti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
