摘要

针对高推质比航空发动机结构设计，提出了航空发动机转子结构布局优化设计方案。对总体结构布局的优化可以有效提高材料使用效率，获取更优的力学特性，减小结构质量以提高推质比。介绍了转子结构布局的研究内容，给出了结构布局优化设计方法，并通过对高负荷转子结构系统的布局优化设计，验证了结构布局设计方法的可行性。算例结果表明：该方法可使结构效率损失系数降低0.335，方法的创新对航空发动机转子系统初始结构设计具有指导意义，对转子结构设计方案筛选和缩短设计周期具有重要的作用。

Abstract

For the structural design of high thrust-mass ratio aero-engine

the method of optimum design of aero-engine rotor structure was put forward. The optimization of the overall structure layout can effectively improve the material utilization efficiency

obtain higher mechanical properties

reduce the structural mass and increase the thrust-mass ratio. The research content of the rotor structure layout was introduced

and the optimum design method of the structure layout was given. The feasibility of the structure layout design method was verified by optimizing the layout of the high load rotor structure system. The numerical results showed that this method can reduce the structural efficiency loss coefficient by 0.335

and the research content was of guiding significance to the initial structure design of the aero-engine rotor system

playing an important role in screening the design scheme of the rotor structure and shortening the design cycle.
