Vulcain is a family of European first stage rocket engines for Ariane 5 and 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.

The Vulcain 2 engine delivered a thrust in the order of 130 tonnes. This progress was achieved by concentrating an extremely powerful turbopump into a relatively compact volume and by mastering the extreme temperatures involved.

The development of the Vulcain-2 cryogenic engine forms part of ESA’s Ariane-5 Evolution Programme, which was endorsed by the Ministers of the Agency’s Member States in October 1995, at the Ministerial Council in Toulouse. Vulcain-2 is an improved version of the original Vulcain engine powering the main cryogenic stage of the Ariane-5 ...

2018年1月29日 · Vulcain 2.1为“阿丽亚娜6号”提供动力，这颗卫星运载工具将于2020年由欧洲空间局(ESA)送往太空。 就像Ariane 6的其余部分一样，Vulcain 2.1由欧洲航空航天公司Airbus和法国工程公司Safran的合资企业ArianeGroup组装而成。

2024年5月13日 · The Vulcain 2.1 is a liquid-fueled rocket engine that utilizes cryogenic propellants, namely liquid oxygen (LOX) and liquid hydrogen (LH2). It operates on a gas generator cycle, where a small portion of the propellants is burned in a separate combustion chamber to drive the turbopumps that feed the main combustion chamber.
