The invention provides a propeller-driven aircraft lift characteristic calculation method considering dynamic influence. The lift coefficient generated by the propeller-driven aircraft and the pulley thereof is obtained by taking full advantage of the influence of the attack angle, the speed, the engine tension, the number of engines, the size and position of an engine nacelle, the tension line attack angle, the wing mounting angle, the propeller diameter, the flap deflection angle, the flap chord length, the wing elongation and aspect ratio, the propeller slip flow deflection angle and the slip flow viscosity loss on the lift; the method is used for calculating the lift force generated by the propeller-driven aircraft and the slip flow of the propeller-driven aircraft, the lift force generated by the propeller-driven aircraft and the slip flow of the propeller-driven aircraft can be accurately obtained, and effective support can be provided for design, improvement and control of the propeller-driven aircraft.
