Abstract

In the design of advanced Aero-Engines, it is necessary to carry out an effective quantitative analysis of the internal relations between structural features and mechanical characteristics. According to the structural features, function and performance of aero gas turbine engine, the conception and connotation of Structural Efficiency are proposed. By evaluating the Structural Efficiency, the benefits of the structural system can be quantitatively analyzed, to evaluate the contribution of the structure adopted in the Aero-Engine design process to the performance improvement of the whole engine. In this paper, the structural efficiency coefficient of one typical high bypass ratio turbofan engine is calculated by establishing appropriate evaluation parameters, and consequently the direction of structural optimization is pointed out.
