La France (airship)
The ''La France'' was a French Army non-rigid airship launched by Charles Renard and Arthur Constantin Krebs on August 9, 1884. Collaborating with Charles Renard, Arthur Constantin Krebs piloted the first fully controlled free-flight with the ''La France''. The long, airship, electric-powered with a zinc-chlorine flow battery completed a flight that covered in 23 minutes. It was the first full round trip flight with a landing on the starting point. On its seven flights in 1884 and 1885 the ''La France'' dirigible returned five times to its starting point. Hangar The ''La France'' was constructed in Hangar "Y" at Chalais-Meudon near Paris in 1879. Hangar "Y" is one of the few remaining airship hangars in Europe.

Chalais-Meudon
Chalais-Meudon is an aeronautical research and development centre in Meudon, to the south-west of Paris. It was originally founded in 1793 in the nearby Château de Meudon and has played an important role in the development of French aviation. Starting with the development and production of balloons, the site has been a centre of aviation development, mainly but not exclusively military, ever since. Many famous French aircraft designers and engineers worked here or used its resources, such as hangars, wind tunnels, and laboratories to further their activities, and the site continues as an aerospace research hub into the 21st century. The site was the original home of the world's first aviation museum, now known as the Musée de l'air et de l'espace at Paris–Le Bourget Airport. History Balloons The story of aviation at Chalais-Meudon starts in October 1793 when the French Committee of Public Safety ordered the construction of an observation balloon capable of carrying two obs ...

Aviation History Of France
Aviation includes the activities surrounding mechanical flight and the aircraft industry. ''Aircraft'' include fixed-wing and rotary-wing types, morphable wings, wing-less lifting bodies, as well as lighter-than-air aircraft 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. Clément Ader built the "Ader Éole" in France and made an uncontrolled, powered hop in 1890. This was the first powered aircraft, although it did not achieve controlled flight. Some of the most significant advancements in aviation technology came with the controlled gliding flying of Otto Lilienthal in 1896. A major leap followed with the construction of the ''Wright Flyer'', 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 engine which enabled aviation ...

Airships Of France
An airship, dirigible balloon or dirigible is a type of aerostat (lighter-than-air) aircraft that can navigate through the air flying under its own power. Aerostats use buoyancy from a lifting gas that is less dense than the surrounding air to achieve the lift needed to stay airborne. In early dirigibles, the lifting gas used was hydrogen, due to its high lifting capacity and ready availability, but the inherent flammability led to several fatal accidents that rendered hydrogen airships obsolete. The alternative lifting gas, helium gas is not flammable, but is rare and relatively expensive. Significant amounts were first discovered in the United States and for a while helium was only available for airship usage in North America. Most airships built since the 1960s have used helium, though some have used hot air. The envelope of an airship may form the gasbag, or it may contain a number of gas-filled cells. An airship also has engines, crew, and optionally also payload accommo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
19th-century French Experimental Aircraft
The 19th century began on 1 January 1801 (represented by the Roman numerals MDCCCI), and ended on 31 December 1900 (MCM). It was the 9th century of the 2nd millennium. It was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanded beyond its British homeland for the first time during the 19th century, particularly remaking the economies and societies of the Low Countries, France, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Catholic Church, in response to the growing influence and power of modernism, secularism and materialism, formed the First Vatican Council in the late 19th century to deal with such problems and confirm ce ...

Hydrogen
Hydrogen is a chemical element; it has chemical symbol, symbol H and atomic number 1. It is the lightest and abundance of the chemical elements, most abundant chemical element in the universe, constituting about 75% of all baryon, normal matter. Under standard conditions, hydrogen is a gas of diatomic molecules with the chemical formula, 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 discovere ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Airship Hangars
Airship hangars (also known as airship sheds) are large specialized buildings that are used for sheltering airships during construction, maintenance and storage. Rigid airships always needed to be based in airship hangars because weathering was a serious risk. History Early hangars The first real airship hangar was built as Hangar "Y" at Chalais-Meudon near Paris in 1879 where the engineers Charles Renard and Arthur Constantin Krebs constructed their first airship " La France". Hangar "Y" is one of the few remaining airship hangars in Europe. The construction of the first operational rigid airship LZ1 by Count Ferdinand von Zeppelin started in 1899 in a floating hangar on Lake Constance at Manzell today part of Friedrichshafen. The floating hangar turned into the direction of the wind on its own and so it was easier to move the airship into the hangar exactly against the wind. For the same reason later rotating hangars were built at Biesdorf (today part of Berlin) and at t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The 1884 Krebs & Renard First Fully Controllable Free-flights With The LA FRANCE Dirigible Near Paris (Krebs Arch
''The'' is a grammatical article in English, denoting nouns that are already or about to be mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with nouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of the archaic pronoun ''thee'') ...
