摘　　要：基于风险评估技术,研究了航空发动机设计过程质量控制点的设置方法。将每项设计工作的失效视为一个风险源,根据制定的具体化风险准则确定其后果严重性、发生可能性以及风险等级大小,在设计过程中设置不同层次的质量控制点。结合航空发动机方案阶段的设计流程,采用该方法进行分析,表明了将风险评估技术应用于设计质量控制点设置或优化的可行性和有效性。The quality control point constructing methods of aero-engine design process was studied basedon risk evaluation technology. Each design work failure could be regarded as a risk source, and according tothe formulated refined risk criterion, the consequences, probability and risk grade could be determined.Consequently, multi-level quality control points could be set in the design process. This method has beenapplied to the conceptual design phase of aero-engines. The results demonstrate that the method of settingor optimizing design quality control points based on risk evaluation is practicable and effective.
