| 摘要： | The primary objective of this research effort is to identify failure modes and hazards associated withseveral configurations of multicopter concept vehicles supplied by NASA. Functional hazard analyses(FHA) and failure modes and effects criticality analyses (FMECA) are performed for each of the eightvehicle configurations under review. Conceptual design of notional powertrain configurations (turboshaft,electric, hybrid electric), notional thrust control systems (rpm control and collective control), andnavigation control systems for the concept vehicles were to support the reliability and safety analysis andto assess whether a mission can be completed safely. Two kinds of analyses are performed: static safetyanalysis which enable the quantification of the likelihood of individual events, and dynamic safety analyseswhich allows the investigation of multiple time-dependent failures. Their objective is to quantify thelikelihood of catastrophic failures. |
