The scale of this rocket paper model is 1:96, it is designed by niels. Ariane 3 was a European expendable carrier rocket, which was used for eleven launches between 1984 and 1989. It was a member of the Ariane family of rockets, derived from the Ariane 2, although it flew before this. It was designed by the Centre National d'Etudes Spatiales, and produced by Aérospatiale in France.
The Ariane 3 followed the same basic design as the earlier Ariane 1, but incorporated modifications made for the Ariane 2. Unlike the Ariane 2, two solid-fuelled PAP strap-on booster rockets were used to augment the first stage at liftoff.
The core of the Ariane 3 was essentially an Ariane 2. The first stage was powered by four Viking 2B bipropellant engines, burning Nitrogen tetroxide in an UH 25 oxidiser, which was a mixture of three parts UDMH and one part Hydrazine. The second stage was powered by a Viking 4B, which used the same fuel-oxidiser combination. The third stage used a cryogenically fuelled HR7-B engine, burning liquid hydrogen in liquid oxygen. On some flights, a Mage 2 kick motor was flown as a fourth stage.
