国外航天器在轨故障统计与分析
Analysis on Foreign Spacecraft In-orbit Failures
摘要
Abstract
Through studying the in-orbit failures of spacecraft,the rule of failure occurrence can be gotten which can help taking precautionary or corrective measures.On the basis of failure data collected,satellite in-orbit failures are categorized and analyzed,and the current of in-orbit failure is summarized.The number of spacecraft failure increases every year,and the failure numbers of attitude and orbit control subsystem（AOCS）,power subsystem and propulsion subsystem are more than the other subsystems.Moreover,the failures of power,integrative electronics,propulsion,thermal,environmental control and life support subsystems are analyzed.The result shows that the most failures of power subsystem are solar array mechanical failure,interconnect failure,and solar cell failures;for integrative electronics failure,the most transient failures are attitude and orbit control failure and communication subsystem failure,and the most permanent failures are attitude and orbit control computer failure and electric equipment failure;the propulsion subsystem failure in high orbit is mostly.And then,in order to reduce the occurrence probability of spacecraft failure and decrease the in-orbit risk of spacecraft,precautionary or corrective countermeasures are to be adopted,which are enforcing failure simulation in initial stage,building specific space environment model,normalizing space environment design method,adopting failure diagnose and flexibility design,developing long life study of move or turn machine,and optimizing test items before spacecraft launching.关键词
