基于故障树的某型无人机助推器分离异常故障诊断方法

Fault analysis of booster separation and improvement for a certain type of UAV Based on the fault tree model

由于故障树的各节点之间有很强的逻辑和层次关系,因而由故障树生成的诊断模式具有很强的条理性和针对性,本文简述了故障树建模方法和故障处理步骤,并通过某型无人机助推器故障诊断实例得到了验证,该方法可适用于目前大多数飞行器故障分析。

Due to the close logical and hierarchical relationship between the incentives of each node in the fault tree, the diagnostic patterns generated by the fault tree are well organized and targeted. This paper describes the modeling method and fault disposal process for the fault tree. This method is verified by a fault tree example which the rocket booster doesn＇t separate from UAV. The result indicates that the method is efficient, reliable, and suitable for most existing faults of UAV.
