| Abstract: | In order to meet the urgent needs for enhancing system safety level of aero-engine,the required attributes and technology foundations of systematic model for engine life limited parts operating boundary analysis (SMELLIPOBA) was analyzed.The development of relevant technology foundations in recent years was discussed based on substantive aero-engines characteristics and some exploratory research results.The development situation of SMELLIPOBA was introduced.The research directions in the future of this field were predicted.The conclusion can be drawn is that:SMELLIPOBA which meets the airworthiness requirements should includethe following five characteristics namely:coupling, dynamicity, uncertainty,multidiscipline and multiscale,and development of SMELLIPOBA in future will mainly depends on the development in these characteristics as well. |
