<p>This invention is applicable to the production of ski sporting equipment (ski jumping). The aim of the invention is to reduce unfavourable air resistance of the skis during flight and to raise the take-off power index thus raising the skis aerodynamic quality during the flight. This new construction differs from the previous by the chinks that are located along the ski, one by one, excluding ski ends and space for the ski boot. These chinks reduce unfavourable air resistance and raise take-off power index. By raising aerodynamic quality of the skis, flight time is prolonged and distance of the jump is increased.</p> |
