Musée Aéronautique Et Spatial Safran
The Musée aéronautique et spatial Safran ( en, Aeronautics and Space Museum Safran, italic=yes) is a French private aviation museum located in Melun, Seine-et-Marne. Established in May 1989 the museum contains a large collection of historic and modern aircraft engines. These engines have been produced by various French engine manufacturers such as Gnome et Rhône and Snecma which are now part of the present day Safran company. The latter is the creator and manager of the museum. The main exhibits are piston engines and turbojets that powered aircraft as well as rocket engines used for aircraft and spacecraft. All the exhibits were developed and produced by companies that were eventually merged into the Safran group. History In 1985 the Musée de l'Air et de l'Espace, Le Bourget held more than 1,000 historic aero engines. Snecma signed an agreement to allow their restoration and future care. The agreement stated that employees of Snecma would restore the engines as volunteer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Melun
Melun () is a Communes of France, commune in the Seine-et-Marne Departments of France, department in the Île-de-France Regions of France, region, north-central France. It is located on the southeastern outskirts of Paris, about from the kilometre zero, centre of the capital. Melun is the prefecture of the Seine-et-Marne, and the seat of one of its ''arrondissements''. Its inhabitants are called ''Melunais''. History Meledunum began as a Gauls, Gaulish town; Julius Caesar, Caesar noted Melun as "a town of the Senones, situated on an island in the Seine"; at the island there was a wooden bridge, which his men repaired. Roman Meledunum was a ''mutatio'' where fresh horses were kept available for official couriers on the Roman road south-southeast of Paris, where it forded the Seine. Around 500 A.D, Clovis I granted Melun to a Gallo-Roman magnate, Aurelianus (Gallo-Roman), Aurelianus, who had fought for Clovis several times and apparently influenced his conversion to Christianity. ...

Hispano-Suiza
Hispano-Suiza () is a Spanish automotive–engineering company. It was founded in 1904 by Marc Birkigt and Damian Mateu as an automobile manufacturer and eventually had several factories in Spain and France that produced luxury cars, aircraft engines, trucks and weapons. In 1923, its French luxury car arm became a semi-autonomous partnership with the Spanish parent company. In 1946, the Spanish parent company sold all of its Spanish automotive assets to Enasa, a Spanish state-owned vehicle manufacturer, and the French arm continued as an independent aviation engine and components manufacturer under the Hispano-Suiza name. In 1968, Hispano-Suiza was taken over by the aerospace company Snecma, which is now part of the French Safran Group. An attempt to relaunch the marque was made by the company Hispano Suiza Cars associated with the Peralada Group (owned by the Suqué Mateu family) in 2019 with a fully-electric car. History Early years In 1898, a Spanish artillery captain, Emilio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sud Aviation Vautour
The Sud-Ouest Aviation (SNCASO) S.O. 4050 Vautour II (French for ''vulture'') was a French jet-powered bomber, interceptor, and attack aircraft developed and manufactured by aircraft company Sud Aviation. The Vautour was operated by France's ''Armée de l'Air'', having been originally developed by Sud Aviation in response to a French requirement for a jet aircraft for bombing, low-level attack and all-weather interception operations. The Vautour was used in the Force de frappe under the Commandement des Forces Aériennes Stratégiques; each aircraft was suitable for the carriage of a nuclear weapon. The shortcomings of the type as a bomber, such as its lack of radar or other advanced navigation/attack systems, led to the type being replaced by the more capable Dassault Mirage IV. The Vautour never saw combat use with the French Air Force. The only other customer for the Vautour was Israel. During its service with the Israeli Air Force (IAF), the type undertook various missi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guerchais-Roche Émouchet
The Arsenal Émouchet (English: ''Kestrel''), more commonly known as Sports Aériens Émouchet, Air Émouchet, or Guerchais-Roche Émouchet, is a modest performance, single-seat training aircraft, training glider (sailplane), glider designed and first produced in France during World War II. Quantity production continued post-war, when it played an important part in re-equipping the French glider movement through its clubs. Design and development The Émouchet was designed and built by Arsenal de l'Aeronautique during World War II. It is an all wood and aircraft fabric covering, fabric, single seat, open cockpit training and club glider (sailplane), glider influenced, like many others, by the Grunau Baby but distinct from it. The single spar (aviation), spar wings, wooden structures with fabric covering, have a parallel chord (aircraft), chord centre section and tapered outer panels with rounded tips. The trailing edges of these outer panels are occupied with ailerons. There a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blériot XI
The Blériot XI is a French aircraft of the pioneer era of aviation. The first example was used by Louis Blériot to make the first flight across the English Channel in a heavier-than-air aircraft, on 25 July 1909. This is one of the most famous accomplishments of the pioneer era of aviation, and not only won Blériot a lasting place in history but also assured the future of his aircraft manufacturing business. The event caused a major reappraisal of the importance of aviation; the English newspaper ''The Daily Express'' led its story of the flight with the headline "Britain is no longer an Island". It was produced in both single- and two-seat versions, powered by several different engines, and was widely used for competition and training purposes. Military versions were bought by many countries, continuing in service until after the outbreak of World War I in 1914. Two restored examples – one in the United Kingdom and one in the United States — of original Blériot XI a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vulcain (rocket Engine)
Vulcain is a family of European first stage rocket engines for Ariane 5 and the future Ariane 6. Its development began in 1988 and the first flight was completed in 1996. The updated version of the engine, Vulcain 2, was first successfully flown in 2005. Both members of the family use liquid oxygen/liquid hydrogen cryogenic fuel. The new version under development for Ariane 6 will be called Vulcain 2.1. History The Vulcain rocket engine is named in French for Vulcan, the ancient Roman god of fire. Its development, carried out by a European partnership, began in 1988 with the Ariane 5 rocket program. It first flew in 1996 powering the ill-fated flight 501 without being the cause of the disaster, and had its first successful flight in 1997 (flight 502). In 2002 the upgraded Vulcain 2 with 20% more thrust first flew on flight 157, although a problem with the engine turned the flight into a failure. The cause was due to flight loads being much higher than expected, as the inqu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Viking (rocket Engine)
The Viking rocket engines were members of a series of bipropellant engines for the first and second stages of the Ariane 1 through Ariane 4 commercial launch vehicles, using storable, hypergolic propellants: dinitrogen tetroxide and UH 25, a mixture of 75% UDMH and 25% hydrazine (originally UDMH). The earliest versions, developed in 1965, had a sea-level thrust of about 190 kN. By 1971, the thrust had improved to 540 kN, with resulting engine named Viking 1 and adopted for the Ariane program. The engine first flown on the Ariane 1 rocket in 1979 was Viking 2, with thrust further improved to 611 kN. The version used on the Ariane 4 first stage, which used a cluster of four, had 667 kN thrust each. The second stage of Ariane used a single Viking. Over 1000 were built, and achieved a high level of reliability from early in the programme. The 144 Ariane 1 to 4 launchers used a total of 958 Viking engines. Only two engines led to a failure. The first failure (on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Satellite
A satellite or artificial satellite is an object intentionally placed into orbit in outer space. Except for passive satellites, most satellites have an electricity generation system for equipment on board, such as solar panels or radioisotope thermoelectric generators (RTGs). Most satellites also have a method of communication to ground stations, called Transponder (satellite communications), transponders. Many satellites use a Satellite bus, standardized bus to save cost and work, the most popular of which is small CubeSats. Similar satellites can work together as a group, forming Satellite constellation, constellations. Because of the high launch cost to space, satellites are designed to be as lightweight and robust as possible. Most communication satellites are radio Broadcast relay station, relay stations in orbit and carry dozens of transponders, each with a bandwidth of tens of megahertz. Satellites are placed from the surface to orbit by launch vehicles, high enough to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intercontinental Ballistic Missile
An intercontinental ballistic missile (ICBM) is a ballistic missile with a range greater than , primarily designed for nuclear weapons delivery (delivering one or more thermonuclear warheads). Conventional, chemical, and biological weapons can also be delivered with varying effectiveness, but have never been deployed on ICBMs. Most modern designs support multiple independently targetable reentry vehicles (MIRVs), allowing a single missile to carry several warheads, each of which can strike a different target. Russia, the United States, China, France, India, the United Kingdom, and North Korea are the only countries known to have operational ICBMs. Early ICBMs had limited precision, which made them suitable for use only against the largest targets, such as cities. They were seen as a "safe" basing option, one that would keep the deterrent force close to home where it would be difficult to attack. Attacks against military targets (especially hardened ones) still demanded th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turbomeca Astazou
The Turbomeca Astazou is a highly successful series of turboprop and turboshaft engines, first run in 1957. The original version weighed and developed at 40,000 rpm. It was admitted for aviation service on May 29, 1961, after a 150-hour test run. The main developing engineer was G. Sporer. It was named after two summits of the Pyrenees. A simplified version was built by Agusta as the Turbomeca-Agusta TA.230. Design and development The Astazou IIA version was derived from the original Astazou powerplant for use in helicopters. By 1993, 2,200 had been built. As of 2007, it was still in production. However, many aircraft initially equipped with it, especially the heavier ones, have since been upgraded with more powerful engines. The early single-shaft Astazou has a two-stage compressor, with the first stage an axial and the second stage a radial design. It has an annular combustion chamber, after which the combustion gases enter a three-stage axial turbine. Engines have a reduc ...

Snecma M88
The Snecma M88 is a French afterburning turbofan engine developed by Snecma (now known as Safran Aircraft Engines) for the Dassault Rafale fighter. History The program for the M88 arose from a need for a suitable propulsion system for air-superiority and ground-attack missions. In 1983, Dassault Aviation planned to produce a technology demonstrator for the ''Avion de Combat eXpérimental'' (ACX), which was expected to fly in 1986. Although the M88 was intended to be fitted to the definitive aircraft, it was not expected to be ready in time, and the ACX was therefore initially powered by the General Electric F404. Due to the broad application of the new engine (as the aircraft was to replace considerable number of French fleet), it was necessary for the engine to have a high thrust-to-weight ratio, low fuel consumption in all flight regimes, and a long engine life. Additional considerations were afforded to good maintainability, and upgrade potential (73 kN to 105 kN us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
