Embodiment approach
[0043] In the present invention, based on the fault tree analysis method, the risk control is carried out for the long-term on-orbit operation of large manned spacecraft. As can be seen from the above, according to one embodiment of the present invention, the manned spacecraft long-term on-orbit dangerous event analysis method of the present invention specifically includes:
[0044] Step a: Determine the dangerous events during the manned spacecraft’s on-orbit operation, that is, determine the undesired failure consequence state during the manned spacecraft’s on-orbit operation. Then the consequence state of the dangerous event of the manned spacecraft is analyzed, and the severity level of the dangerous event is analyzed.
[0045] Step b: Carry out functional analysis of the manned spacecraft, and on the basis of the functional analysis of the manned spacecraft, classify the functions of the manned spacecraft according to dangerous events. Specifically, it is to establish a ...
