The invention discloses a design method of an aero-engine propeller flange conical surface connecting structure. The design method comprises the steps of S1, determining a large-diameter basic size ofa conical surface shaft and material parameters of a connecting piece; S2, determining a pre-tightening force of a fastener; S3, setting a taper angle of a first outer circular surface and a length of a contact surface; S4, calculating contact pressure of the contact surface; S5, calculating a connection bearing torque; S6, calculating allowable working pressure of the contact surface; S7, setting a size of a flat key, and calculating a bearing torque of the flat key; S8, judging whether a calculation result meets an expected design index or not; and S9, determining a final size of the firstouter circular surface and the flat key. According to the design method of the aero-engine propeller flange conical surface connecting structure, an optimal design of conical surface shaft connectioncan be simply and efficiently completed, a design period is shortened, design cost is saved, and therefore the design of aero-engine parts is better achieved.
