How modern ski work

Finally the winter is here and the skiing season starts!

My slalom-skis arrived today from Austria and I'm really excited . The special thing about them which is also the reason why I'm so excited is that they have a computer chip inside which supports the KERS Technology (KINETIC ENERGY RECOVERY SYSTEM) How does that work?

KERS Technology works like a turbo charger that provides additional power and acceleration by stiffening the tail of the ski in outturns.

The effect: a boost, catapulting the rider into the next turn. Just like when Formula 1 pilots push a button for that extra notch of speed.

HEAD KERS Technology is an electronic, fully automatic and integrated system.

HOW IT WORKS

Skis experience maximum flex at the end of a turn. At this moment the energy is released into the fibers of the tail. The tail of the ski then stiffens up, immediately increasing rebound for maximum acceleration at the end of the outturn.

TECHNICAL BACKGROUND

HEAD KERS Technology is an evolution of the idea behind HEAD’s Intelligence Technology. In addition KERS does not influence the torsional stiffness of the ski, KERS empowers the skis’ longitudinal flex. Also KERS Technology is based on a completely new design capable of accumulating power and keeping it in store for the right moment.
 Piezoelectric fibers transform kinetic energy into electrical energy which is stored. Electrical energy is immediately released to areas of the ski, where additional energy is requested. Timing and release are automatically controlled and coordinated. Depending on the flex pattern of different ski models, sensors are programmed beforehand: the more aggressive the ski has to be, the stiffer the tail will become.

Here are two links that will also explain this again.

Can't wait wait to go skiing!!!
