In order to study and analyze the aerials freestyle athletes in the curve slideway stage of the aerodynamic characteristics, the parameters for the calculation of aerodynamic characteristics using the introduction of the speed of time. By analysis of the CFD method using the technique of Chinese aerials of freestyle skiing athlete Xu Mengtao. The results show that: in the curve slideway, the lift is very small, can be neglected, but because of the relatively large resistance can’t be ignored. When self gravity resistance and athletes of the tangential component is overlapped, sliding speed athletes will decay rapidly. In addition, in order to improve the athlete's movement in the left platform stability. Athletes should be kept away from the vortex region is formed in the slope and vertical wall corner off the platform.
