据报道,国际发射服务公司(ILS)故障监察评审委员会(FROB)日前公布了质子-M/微风-M火箭发射异常的故障调查报告,审查认定本次故障的根本原因是温度过高导致上面级发动机轴承损坏。2012年12月8日,微风-M上面级在发射Yamal-402通信卫星时,由于上面级提前4min关机,卫星只能依靠自身动力到达预定轨道。完成一系列在轨试验后,卫星于2013年1月8日正式服役,但其寿命却因此受到影响,由原先的15年缩短到11年。事故发生后,俄罗斯联邦航天局立即成立了故障调查小组,并在
According to reports, the International Launch Services Corporation (ILS) Failure Monitoring Panel (FROB) recently released a proton-M / Breeze-M rocket launcher fault investigation report found that the root cause of this failure is caused by the temperature is too high level Engine bearing damaged. On December 8, 2012, when the Breeze-M upper-class fired the Yamal-402 communications satellite, the satellite could only rely on its own power to reach the scheduled orbit due to the 4-minute shutdown of the upper level. After completing a series of on-orbit tests, the satellite was officially commissioned on January 8, 2013, but its life expectancy has been affected, reducing from the previous 15 years to 11 years. After the accident, the Russian Federal Space Agency immediately set up a fault investigation team, and at
