Abstract: This paper studies the influence of Gurney flaps（ GF） on flight dynamics characteristics of autogyro,taking a certain autogyro as object. Aerodynamic coefficients of rotor airfoil equipped with GF are calculated by numerical method. Flight dynamics model of autogyro with gurney flaps was established based on autorotation rotor dynamics modeled,which modeling by blade element theory coupled with dynamic inflow theory. The result shows that GF has a great influence on longitudinal trim characteristics of autogiro. GF increases the amount of longitudinal pitch control and decreases the steady rotary speed of autogyro. GF almost does not influence the stability of autogiro,and meanwhile,GF can also reduce the power consumption,which is in favor of flight performance.
