Abstract :Different from previous aerodynamic brake studies where aerodynamic brake is used to support conventional brakes, in this paper, a novel design of wing set for high speed trains insert ignore into journalissuearticles values(HSTs); has been proposed to provide safer and faster movement in curved rails. We have investigated, for the first time, the contribution of those two-axis wings on the running capability of a HST in a curved path to reduce derail or overturn risk. We have put 6 wings, 4 on sides which are proposed first time and 2 on top on each car. We have found that at same speed insert ignore into journalissuearticles values(0.8ma);, minimum radius of curvature decreased from 7km to 3km when the wings are used. In the second part, the advantages of the aerodynamic drag brakes induced from proposed novel design wings at the speed of 0.8ma are discussed.
