The safety assessment process of carrier aircraft's control system

摘要

Carrier aircraft's control system is the core system of carrier aircraft, the existing military standards such as MIL-STD-882E fail to provide specific or sufficient division of safety sessions for the development cycle of such systems and don't specify the kind of safety analysis using, which allows the carrier aircraft's control system safety analysis can't be fully carried out. Therefore, it's the urgent need to put forward a set of safety assessment process for the carrier aircraft's control system. Firstly, This article which submits a detailed work phases of the safety assessment process for carrier aircraft's control system, divides the process into preliminary hazard list and function hazard assessment, preliminary system safety assessment, subsystem system safety assessment, System safety verification corresponding to its four development stages; Secondly, there have many different safety analysis methods which decided by the characteristic of each working stage, such as Fault Tree Analysis and Failure modes and Effects Analysis to analysis component failure, Common Cause Analysis to analysis coupled dangerous, and analysis method for the interactive danger of carrier aircraft's control system is System Control Hazard Analysis; Finally it put forward a comprehensive safety assessment process of carrier aircraft's control system. Safety assessment process proposed this article can guarantee that the safety analysis work of carrier aircraft carries out smoothly.
