SpaceX公司星舰第二次飞行异常情况初步分析

Initial Analysis of Anomalies in the Second Flight of SpaceX’s Starship

2023年11月18日,美国太空探索技术(SpaceX)公司在自建发射场,进行了星舰运载火箭的第二次轨道级发射试验,火箭一级上升段飞行正常,顺利通过最大动压,一二级火箭成功完成热分离,随后一级火箭在翻转过程中多台发动机工作异常,最终爆炸解体,二级火箭在飞行数分钟后发动机异常,触发自毁,未能达到预定轨道,发射失利。通过调研梳理了火箭一二级在发射过程中出现的异常现象,分析可能造成异常现象和飞行失利的原因,并总结经验和启示。

On November 18,2023,SpaceX conducted the second orbital launch test of a Starship carrier rocket at its own launch site.The first stage of the rocket's upward flight was normal and successfully passed the MaxQ.The first and second stages of the rocket successfully completed thermal separation.Subsequently,multiple engines of the first stage malfunctioned during the flipping process,eventually exploding and disintegrating.The second stage experienced engine abnormalities after flying for several minutes,and the rocket ultimately triggered self destruction and failed to reach the predetermined orbit,resulting in a failed launch.Based on the relevant research content,the abnormal phenomena that occurred during the launch of the first and second stages of the rocket were sorted out,and the possible causes of abnormal phenomena and flight failures were analyzed.The experience and inspiration for similar rocket systems were summarized.
