  • A twist fin improved from oblique plate tail was proposed to meet the requirements of vehicle speed and rotating speed matching. According to the characteristics of twist fin providing rolling moment for vehicle, the twist rate and average attack angle were introduced to represent geometric features of twist fin based on the model of oblique plate tail. Based on correction-type blade element theory, four degrees of freedom rigid body equations were established to describe the motion law of aircraft, and the results were compared with the balancing rotating speed obtained by numerical simulation method. The results show that increasing the average attack angle and the twist rate, and reducing the span length of twist fin can improve the vehicle rotating speed, while increasing the root shoot ratio of twist fin has little effect on improving the vehicle balancing rotating speed. When the average attack angle of twist fin stays unchanged, the vehicle balancing rotating speed and twist rate show a linear relationship.
