Abstract

The invention relates to the technical field of aircrafts, and discloses a rapid rudder effect estimation method. The method comprises the steps that CFD calculation is carried out based on the zero-rudder-deviation reference state of the aircraft to obtain the aerodynamic coefficient Cy of a rudder surface under each missile body attack angle alpha under the zero-rudder-deviation reference state;carrying out center interpolation on the aerodynamic coefficient Cy to obtain an aerodynamic coefficient Cy, alpha of the control surface under each missile body attack angle; and based on the binaryarray (alpha, Cy, alpha), calculating aerodynamic coefficient increment caused by control surface deflection delta under any missile body attack angle alpha 0, and estimating the control effect basedon the aerodynamic coefficient increment, so that the high-precision rapid estimation of the control effect can be realized by considering the missile body interference influence.
