一种连续打蜡的滑雪板已经被开发出来,它可以在滑雪板的底部释放一层润滑剂薄膜。这复制了滑雪板中观察到的由摩擦和太阳能加热引起的融水层。该系统在人造(干燥)斜坡上特别有效,滑雪者在塑料刷毛而不是雪上滑行。使用该系统可以达到与雪上相当的速度,这改善了滑雪者的体验。使用聚乙二醇水溶液,塑料斜坡的速度可提高高达 50%。在人造雪上速度提高约 9%,在新鲜高山雪上速度提高 2%。后一个值非常重要,因为它可能是在滑雪比赛中赢得奖牌和进入前十名之外的区别。除了定量数据外,还记录了运动员的定性感知,并表明可以在人造表面上实现像雪一样的感觉。由于润滑系统安装在滑雪板上,因此无论水雾系统是否运行,它都可以提高个人表现。该设计符合滑雪国际管理机构的装备规定,因此可以在比赛中使用。
A continuously waxed ski has been developed that releases a thin film of lubricant under the base of a ski. This replicates the melt water layer observed in snow skis which is caused by frictional and solar heating. The system is particularly effective on artificial (dry) slopes where skiers slide on plastic bristles rather than snow. Speeds comparable to those achieved on snow are achieved using this system and this improves the experience for the skier. Speed enhancements on plastic slopes of up to 50 % have been achieved using solutions of polyethylene glycol in water. There is speed enhancement of approximately 9 % on artificial snow and 2 % on fresh alpine snow. The latter value is highly significant as it can be the difference between winning a medal in ski competitions and finishing outside the top ten. In addition to the quantitative data, qualitative athlete perceptions were also recorded and show that a feel like snow can be achieved on artificial surfaces. Because the lubrication system is attached to the ski, it allows personal performance enhancement irrespective of a water misting system being in operation or not. The design complies with the equipment regulations of the skiing’s international governing body so it can be used in competition.
