In order to achieve high-speed stability control of two-dimensional correction projectile, the spin-decelerating moment of a two-dimensional correct projectile with rubber and fin under different speed was studied by simulation experiment based on the principle of trajectory correction. The equipment motor damping to stir oil which oil box under spin-decelerating moment simulate spin-decelerating moment of the correction projectile. The spin torque calculated by FLUENT simulation software, the oil box simulation result was measured by strain gauge dynamometer, the of the motor and oil box were measured by hall speed sensor, and the test data was analyzed by MATLAB. The experiment result indicates that the designed equipment could meet the test requirement of correction projectile control.
