The purpose of this study is to get a basic knowledge about the aerodynamics about the race suit and the sled surface form processing in the luge sport. The 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 luge track 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 inspected a measurement in JAXA (Japan Aerospace Exploration Agency) whether profiling of the treatment of the race suit and the sled surface had influence that how was it on aerodynamic drag this time. That we could plan reduction of the aerodynamic drag was inspected by doing the race suit surface in the shape of several kinds of stripe. In addition, we was going to inspect it how aerodynamic drag changed by affixing tape to the surface of the pod of sled in the shape of stripe.
