由欧洲动力装置制造公司(SEP)牵头、MBB等来自12个欧洲国家的二十多家公司参与研制和建造的火神发动机已进入样机试验阶段,于1990年7～9月间在巴黎西部的弗农进行了首批7次地面试车。这种欧洲目前最大的低温火箭发动机将作为欧空局阿里安5大型运载火箭的主动力,为期10年的研制计划(从1985年1月开始)共将耗资7.7亿美元。 火神发动机的真空推力为1070千牛,工作时间为600 Led by the European Power Plant Manufacturing Company (SEP), the Vulcan engine, which was developed and built by more than 20 companies including MBB from 12 European countries, has entered the prototype test phase and was tested in the western part of Paris from July to September 1990 Vernon conducted the first 7 ground-based tests. This European, currently the largest low-temperature rocket engine, will be the main force behind the ESA Arian 5 large launch vehicle. The 10-year development plan (starting January 1985) will cost a total of $ 770 million. Vulcan engine vacuum thrust of 1070 kN, working hours of 600
