Some maggots are asking how to quantify the performance of an alpine ski? There is a serious modelling of regular shaped ski, reported by Swiss institute (Federolf et al) under the title "Finite element simulation of the ski–snow interaction of an alpine ski in a carved turn" published in Sports Engineering, 2010, Volume 12, Number 3, Page 123. Federolf found that /under normal conditions/ so called "carving ski" cannot really carve but it is wildly skidding aside. The sacred "radius" is just a house number! We are working on testing RaxSkis under equal conditions.
Yet even if you do not trust the experimental physics, you may be able to evaluate some facts when comparing regular ski with the RaxSki:
how easy is a ski turn.
Well, a shorter ski should have an advantage here. Moreover, when you lift its tip, the RaxSki will pivot on its rear fins having the total length of 10cm. 10cm is a little shorter than 160 or 180cm of your regular ski.
how good is the carved turn / we want to keep on carving, to avoid skidding aside
Well, the fins and wings can cut much deeeper than the sharpest ski edge, so holding the curve radius.
can I execute carved turns with radii between 1m and 40m on the same ski
The answer is YES for the RaxSki and NO for any other ski.
can I vary the radius during the execution of a carved turn
The same as above
There is a simple method how to evaluate the tracking of your ski:
read your own tracks
Do you really think any other ski would hold the track on this >50° wall ?
