去年12月中旬,阿里安5型火箭将欧洲航天局的X射线多用途望远镜(XMM)送入轨道,因此最终证明了欧洲新型运载火箭的可靠性,并为未来发射重型卫星开辟了市场。XMM望远镜是欧洲有史以来最大的卫星。编号为504号的阿里安5型火箭飞行十分顺利。主发动机点火7秒钟后,两个固体燃料助推器也同时点火。经过5秒钟垂直飞行,就逐渐转向东北,2分钟后助推器分离,继续飞行1分钟后,有效载荷的整流罩分离。飞行不到10分钟,低温液体主发动机关闭并脱落,几秒钟后二级发动机点火。飞行近20分
In mid-December last year, the Allianz 5 rocket brought the European Space Agency’s X-ray multipurpose telescope (XMM) into orbit, thus ultimately demonstrating the reliability of the new European launch vehicle and opening up the market for the launch of heavy-satellites in the future. XMM telescope is Europe’s largest satellite ever. The No. 5 Arian 5 rocket flies very well. Seven seconds after the main engine was fired, both solid-fuel booms were also fired. After 5 seconds vertical flight, it gradually turned to the northeast, 2 minutes after the booster separation, continued flight 1 minute after the separation of the payload of the fairing. Within 10 minutes of flight, the cryogenic liquid main engine shuts off and falls off, and the second stage engine ignites after a few seconds. Nearly 20 minutes flight
