Here is some video files, demonstrating situations where using of new ski constructions would help.

The ski tips collisions and overcomings during
mass-starts . This causes the speed losses and the fall danger. The twisted-tip ("s-tip") ski construction has evident advantage at this situation. To make You sure at this we offer to perform a simple tip collision experiment: |
|
At the final pushing off stage the ski tip is coming into
the snow bank. The biathlonist moves the ski up ahead and the header rakes up the snow with its surface from the snow bank. The biathlonist pulls the ski to himself but the on the header snow mass pulls it down . The biathlonist moves as usual the ski to the first pushing off stage, but the lowered ski tip strikes onto the track and significantly brakes the skier movement. The twisted-tip ski construction ("s-tip") at this situation would provide raising out of snow of the ski tip by the up ahead ski move. The snow mass would not be raked up or be significantly less raked up at this situation. (Look 3D model in patent description). |
|
The ski tip by the on track strike rakes up the snow. That
causes the biathlonist ski rotation about at 90° relative to the move direction.
The fall is inevitable. By use the "parallelogram" ski ("r-shift") construction at this situation the on track ski strike would be damped and the snow raking up would be much less, because the internal edge has an obtuse angle. A twisted-tip ski would slide at this situation without significant resistance. By the use the new construction ski this falls could be avoided. |

Asymmetrical ski ("Slash") avoid the snow raking up by the ski tip and tail. |
Ski tails collisions have unfavorable influence on ski sliding too. Asymmetrical ski construction ("Slash") provides soft ski sliding-off from another ski. Asymmetrical ski also avoids the snow raking up by the ski tip and tail. |
