民用航空发动机型号审定概念设计阶段风险模型

Risk model in conceptual design phase of civil aero-engine type certification

为了在审定项目概念设计阶段识别潜在风险并规划处理措施以提高审定效率,通过综合条款分类统计、符合性方法及实施风险、技术要点解析等方法建立了典型民用航空发动机概念设计阶段工作模型,并开发了条款工作状态信息表。模型在某型民用航空发动机型号审定的实施识别了278项潜在风险,并针对典型结构完整性条款从要求确定到设计实现各个过程的潜在风险进行了详细分析,验证了模型的有效性。

A systematic working mechanism for risk identification in conceptual design phase of civil aero-engine was established to promote efficient type certification with corrective actions.The mechanism comprehensively categorized the risks of regulations,means of compliance,implementations and critical technical points,by which the regulation terms information table was developed.278 potential risks were identified by regulation terms information table utilization in specific civil aero-engine model.In addition,the potential risk of typical rotor integrity regulation in process from requirement definition to design implementation was analyzed in detail,which verified the mechanism and regulation terms information table.
