今年1月24日当地时间下午6时37分,从法属圭亚那群岛库鲁航天中心发射的一枚“阿丽亚娜”44LP大型运载火箭,在飞行了约7分7秒后,由于第三级氢氧发动机转速高达13000转/分的液氧涡轮泵的一个轴承因温升太高而损坏,导致涡轮泵失效,发动机故障,未能将其运载的一颗“土耳其卫星”1号和一颗“欧洲电信卫星”2F5号送入预定轨道,整个第三级火箭连同两颗通信卫星最终坠入西非海岸数百公里外的大西洋中。这是自“阿丽亚娜”火箭1979年首次成功发射以来的第6次发射失败,也是“阿丽亚娜”火箭自从1982年以来
On January 24 this year, at 6:37 p.m. local time, a “Ariane” 44LP large launch vehicle launched from the Kourou Space Center in the French-Guyanese Islands flew for about 7 minutes and 7 seconds. As a result of A third stage oxyhydrogen engine speed up to 13000 RPM liquid oxygen turbo pump bearing due to a temperature rise is too high, resulting in failure of the turbo pump, engine failure, failed to carry a “Turkish satellite” 1 and a “Eurosatellite” 2F5 into orbit, the entire third stage rocket, together with the two communications satellites, eventually fall into the Atlantic Ocean hundreds of kilometers away from the West African coast. This is the 6th launch since the first successful launch of the “Ariane” rocket in 1979 and the “Ariane” rocket since 1982
