Luge sport is adopted as one of the sled sports in the Winter Olympics game, and it is one of a certain very popular sports in Europe. A player rides on the sled, and drives on the course at a speed which reaches best 140km/h on the ice track. It becomes the important point of view of the performance boost how aerodynamic drag is reduced in sliding. The influence of the driving form that it is formed by a sled with the player was verified at 2m x 2m Low-speed Wind Tunnel of Wind Tunnel Technology Center in JAXA. We lowered front projection area when I compared the sled of the improvement type with the current model, and that the improvement type that raised a rectification effect reduced aerodynamic drag of about 7-9% was checked. In Single use sled, a riding form to lift a femoral region a little was advantageous to aerodynamic drag reduction. In addition, it was observed affecting the flow of air the shape of pod of sled. That improvement could reduce aerodynamic drag to Doubles use sled equally was checked.
