Mélanie (rocket)
Mélanie is a French solid rocket motor, 16 cm in diameter, initially used as first stage of the Monica rocket. There are two versions, Mélanie and ''"2Mélanie"'' (exact name unknown) : The first version was used on Monica I, II and IVA; while the improved ''"2Melanie"'', with twice the propellant, was used on Monica III, IVB and V. Melanie was later used in several ATEF and ONERA rockets. In the ONERA rockets, such as Daniel, Antarès and Berenice, Melanie was placed inside a 22 cm diameter cylindrical housing. This version delivered a total impulse of 48 kN.s with about 22 kilograms of propellant.

Rocket
A rocket (from , and so named for its shape) is a vehicle that uses jet propulsion to accelerate without using any 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. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monica (rocket)
Monica is the designation of a small French sounding rocket. It was intended as a cheaper counterpart to the relatively expensive Veronique rockets. Monica was a 3-stage rocket, with all stages burning solid fuel: the ''Melanie'' (burning Plastolite) for the first stage and ''Theodore'' and ''Oreste'' (burning Epictete) for the second and third stages. The first stage delivered 450 daN (decanewtons) for 3 seconds and the two upper stages deliver 50 daN for 15 and 5.5 seconds, respectively. It was built in several versions (Meteo, Monica I to V, MD-01, Grannos), which were between 3.05 and 6.27 m long and had a takeoff weight between 62 and 154 kg. It was launched several times between 1955 and 1962 at the CIEES launch site in Hammaguir, French Algeria, and the Ile du Levant site in France. The Monica design process encountered a number of difficulties, leading to many failed tests and the early cancellation of the program in 1962. However, elements of its design were ...

ONERA
The Office National d'Études et de Recherches Aérospatiales ( English: National office for aerospace studies and research) or ONERA, dubbed ''The French Aerospace Lab'' in English, is the French national aerospace research center. Originally founded as the ''Office National d’Études et de Recherches Aéronautiques'' (National Office for Aeronautical Studies and Research) in 1946, it was relabeled in 1963. It is France's leading research center in aerospace and defense. It covers all disciplines and technologies in the field. Numerous high-profile French and European aerospace programs have passed through the ONERA since its creation including the Ariane family of launch vehicles, the Concorde supersonic airliner, the Dassault Mirage family of fighter aircraft and the Rafale, the Dassault Falcon family of business jets, Aérospatiale and later Airbus projects, missiles, engines, radars and many more. Under the supervision of the Ministry of the Armed Forces, it is a p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Daniel (rocket)
Daniel (OPD-220-ADX) is the designation for a French experimental rocket A rocket (from , and so named for its shape) is a vehicle that uses jet propulsion to accelerate without using any surrounding air. A rocket engine produces thrust by reaction to exhaust expelled at high speed. Rocket engines work entirely ..., a precursor to the Israeli Jericho ballistic missile. Description It consisted of 3 stages: a SPRAN-50 first stage, a Jericho second stage and a Mélanie third stage. Daniel was capable of reaching a maximum altitude of 130 km and had a takeoff weight of 1000 kg, a diameter of 0.40 m and a length of 8.40 m Launches Daniel was launched three times between 1959 and 1961 by ONERA from Centre d'Essais et de Recherches d'Engins Speciaux - Ile de Levant.

Antarès (OPd-56-39-22D)
The Antarès (OPd-56-39-22D) was a French multistage rocket designed by ONERA for reentry studies. In the late 1950s, the study of missile warhead reentry necessitated the development of a more robust rocket than the existing OR, VD and OPd series. The Antarès rocket, designated OPd-56-39-22D during its developmental phase, was designed to facilitate the study of kinetic heating on objects flying at speeds up to Mach number, Mach 7. Description Measuring 12.2 meters in length and boasting a takeoff weight of up to 1785 kg, the rocket consisted of four stages. Three of these stages were ignited in an upward trajectory, reaching altitudes of up to 150 km, while the fourth stage accelerated the payload during its descent. Utilizing all four stages during ascent, Antares had the capability to send a payload of 35 kg to an altitude of 280 km. The first stage featured a SEPR 734-1 Vesuve motor with a diameter of 56 cm and a length of 3.5 m, delivering a tota ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bérénice (rocket)
Bérénice was the designation of a four-stage French atmospheric reentry test rocket, developed by O.N.E.R.A. (''Office National d'Etudes et de Recherches Aérospatiales''). Description Bérénice was long, possessed a diameter of and weighed at launch. The takeoff thrust of Bérénice, which could carry a payload of to a height of , amounted to . The first stage, a SEPR-739 ''Stromboli'', was stabilised by four SEPR-P167 rockets developing . The second stage consisted of a SEPR-740 ''Stromboli'', almost identical to the first stage. The third stage was a SEPR-P200 ''Tramontane'' and the fourth stage comprised a '' Mélanie'' rocket and payload. Launches The twelve production rockets, Bérénice 001 to Bérénice 012, were launched by ONERA from Ile du Levant from 1962 to 1966.

French Space Program
The French space program includes both commercial spaceflight, civil and military spaceflight activities. It is the third oldest national space program in the world, after the Soviet space program, Soviet (now Roscosmos, Russian) and Space policy of the United States, American space programs, and the largest space program in Europe. Background Space travel has long been a significant ambition in French culture. From the Gobelins Manufactory, Gobelins' 1664 tapestry representing a space rocket, to Jules Verne's 1865 novel ''From the Earth to the Moon'' and George Méliès' 1902 film ''A Trip to the Moon'', space and rocketry were present in French society long before the technological means appeared to allow the development of a space exploration program. During the late 18th century, Jean-François Pilâtre de Rozier, Jacques Charles and the Montgolfier brothers are seen as worldwide precursors and explorers of aeronautics, with the world record altitude then reached by a human a ...
