The invention provides a propeller-driven aircraft resistance characteristic calculation method considering dynamic influence. The influence of the attack angle, the speed, the engine tension, the engine number, the engine nacelle size and position, the tension line attack angle, the wing installation angle, the propeller diameter, the flap deflection angle, the flap chord length, the wing elongation and the aspect ratio, the propeller slip flow deflection angle and the slip flow viscosity loss on the resistance is fully considered, and the resistance coefficient of the propeller aircraft slip flow can be accurately obtained. The method is used for calculating the resistance generated by the slipstream of the propeller-driven aircraft, and can provide effective support for design, improvement and control of the propeller-driven aircraft.
