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.
