Aigle (rocket)
Aigle (French for ''eagle'') was a French experimental rocket launched several times between 1960 and 1961. The Aigle was propelled by 984 kilograms of solid fuel Solid fuel refers to various forms of solid material that can be burnt to release energy, providing heat and light through the process of combustion. Solid fuels can be contrasted with liquid fuels and gaseous fuels. Common examples of solid fuels ... and measured 55 cm in diameter. It could propel 360 kilograms of payload to an altitude of up to 6 kilometers. With the addition of an extra booster it became the Éridan.

French Language
French ( or ) is a Romance language of the Indo-European family. It descended from the Vulgar Latin of the Roman Empire, as did all Romance languages. French evolved from Gallo-Romance, the Latin spoken in Gaul, and more specifically in Northern Gaul. Its closest relatives are the other langues d'oïl—languages historically spoken in northern France and in southern Belgium, which French ( Francien) largely supplanted. French was also influenced by native Celtic languages of Northern Roman Gaul like Gallia Belgica and by the ( Germanic) Frankish language of the post-Roman Frankish invaders. Today, owing to France's past overseas expansion, there are numerous French-based creole languages, most notably Haitian Creole. A French-speaking person or nation may be referred to as Francophone in both English and French. French is an official language in 29 countries across multiple continents, most of which are members of the ''Organisation internationale de la Francophonie'' ...

Rocket
A rocket (from it, rocchetto, , bobbin/spool) is a vehicle that uses jet propulsion to accelerate without using the surrounding air. A rocket engine produces thrust by reaction to exhaust expelled at high speed. Rocket engines work entirely from propellant carried within the vehicle; therefore a rocket can fly in the vacuum of space. Rockets work more efficiently in a vacuum and incur a loss of thrust due to the opposing pressure of the atmosphere. Multistage rockets are capable of attaining escape velocity from Earth and therefore can achieve unlimited maximum altitude. Compared with airbreathing engines, rockets are lightweight and powerful and capable of generating large accelerations. To control their flight, rockets rely on momentum, airfoils, auxiliary reaction engines, gimballed thrust, momentum wheels, deflection of the exhaust stream, propellant flow, spin, or gravity. Rockets for military and recreational uses date back to at least 13th-century China. Signific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solid Fuel
Solid fuel refers to various forms of solid material that can be burnt to release energy, providing heat and light through the process of combustion. Solid fuels can be contrasted with liquid fuels and gaseous fuels. Common examples of solid fuels include wood, charcoal, peat, coal, hexamine fuel tablets, dry dung, wood pellets, corn, wheat, rye, and other grains. Solid fuels are extensively used in rocketry as solid propellants. Solid fuels have been used throughout human history to create fire and solid fuel is still in widespread use throughout the world in the present day. Types of solid fuels Wood Wood fuel can refer to several fuels such as firewood, charcoal, ''wood chips'' sheets, pellets, and sawdust. The particular form used depends upon factors such as source, quantity, quality and application. In many areas, wood is the most easily available form of fuel, requiring no tools in the case of picking up dead wood, or few tools. Today, burning of wood is the largest use ...

Éridan (rocket)
The Éridan is a two-stage French sounding rocket, which resulted from the use of the Stromboli engine of the Dragon and/or Dauphin as first and second stage. It belonged thereby to a family of solid-propellant rockets from the Belier (rocket), the Centaure (rocket) Centaure was a two-stage French sounding rocket consisting of a Belier (rocket) starting stage and a Venus upper stage. It was operated by CNES between 1961 and 1986. The Centaure has been built in a number of 230 and has been launched from th ..., to the Dragon, the Dauphin and the Eridan. As the most powerful version of this series it could lift payloads from 100 to 420 kg to heights of 200 to a maximum of 460 km. Its climbing time is between 230 and 350 seconds.Les débuts de la recherche spatiale française 2846082154 IFHE,, Institut français d'histoire de l'espace - 2007 Intéressés, ils demandèrent au CNES d'envisager sérieusement un projet d'astronomie spatiale d'envergure qui serait réali ...
