Abstract
A style of ski jumping has been changed from a parallel style to the present V-style. The glide ratio varies in jumping styles. The glide ratio and the pitching moment of different jumping styles were examined with wind tunnel experiments by using a replica of a human figure. Opening angle between skis, spacing of skis and a posture of the figure were defined as parameters. It was observed that the glide ratio of the V-style was higher than that of the parallel style at the same angle of attack. A stoop shouldered style was also effective to increase the glide ratio. Differences of the flow field among jumping styles were observed with cotton balls and a tuft method in a smoke wind tunnel. While strong but narrow band downwash was appeared in a wake of the parallel style, wide but weaker band downwash was seen in that of V-style.
