By introducing and summarizing the traditional safety analysis method

a model-based safety analysis process and method for aero-engine were proposed. From the property of the aero-engine

unified safety analysis and performance design achieved the goal of balance between them. This could guarantee the consistency

integrity and objective of the analysis results. The three key technical breakthroughs during the safety analysis process and method are:(1) the description method of failure modes; (2) the classification and location methods of the key impact factors; (3) safety analysis verification methods.
