The invention belongs to the technical field of propeller aircraft rolling moment calculation, and particularly relates to a propeller aircraft rolling moment characteristic calculation method considering dynamic influence. The influence of an attack angle, a sideslip angle, a speed, engine tension, the number of engines, the size and position of an engine nacelle, the diameter and rotating speed of a propeller, a flap deflection angle and a flap chord length on the rolling moment is fully considered, the influence of propeller slip flow and a propeller disc lateral force on the rolling moment is accurately represented, and a propeller aircraft rolling moment coefficient considering the dynamic influence is obtained. The method is used for calculating the rolling torque of the propeller-driven aircraft and can provide effective support for design, improvement and control of the propeller-driven aircraft.
