The article continues the theme of the use of the latest scientific achievements in the field of formation of ice covers and modern methods of inventory preparation in highspeed sports. The first focus is on the problem of the stability of the athlete when cornering at high speeds turns. The article presents the main chronological stages of improving the design of blades for ice sports. The physical features of interaction between ice and athlete skate when cornering and the results of investigation of influence of the properties of the ice cover and the configuration of the blade ridge on the athlete’s stability in short track are considered. Experimental equipment, which allowed to simulate the passage of an athlete turns and a comparative analysis of highspeed properties of various configurations of blades are developed. Experimental data of the influence of the profile and form of the modified blades on the highspeed characteristics were obtained and was offered their new design: the blade has a bend radius and the bearing surface, the angle of sharpening the inner edge of the blade is less than 90 о. Experiments have shown that the proposed design of the blades improves the stability of the athlete during turning, as well as increases the speed characteristics. It is shown that the formation by laser ablation structure on support and lateral surfaces is necessary to improve the speed characteristics of curved blades. It gives a skater advantage at the start and during the race in short track.
