The purpose of this study is to get a basic knowledge about the aerodynamics about the riding form of luge sport. 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 course. 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. It was proved that the turbulence of the flow of the air by the form of the foot was related to aerodynamic drag, and rise in the considerable drag value was seen with a form by turning a foot to the top about 20% as that result. Though rise in drag value was low in comparison with the form to raise a foot, the (raise the head) form to see the front saw about 10% of rise in drag value. The improvement of the driving form, the sled shape and the development of the suit for the game are taken based on this verification in future.
