STABILIZER  BOW

 

 

 

 The stabilizer bow is for reducing the rolling of the rig. It is set in an horizontal plane, with the two sails standing vertically. The bushing "D" is locked on the holding-bar of the rig. the two half-bows are inserted in. the back line maintains the bow curved.
The bow is made with carbon rod Ø3mm.
On each half-bow "A" is bonded a sleeve "B" Ø4x0.5mm, on which is also bonded an anti-rotation sheath "C" Ø6x1mm with a chamfered edge. This male shape, when inserted in the female shaped bushing "D" will prevent the bow to rotate downward.
The bushing "D" Ø6x1mm is in aluminum, as well as parts "B" and "C".
Depending on the wind, the sails can be larger or smaller.
It is also necessary that the pendulum can only pitch. So the pendulum is set on an axis perpendicular to the kite line.

 

The above detail shows how the stabilizer bow is set and assembled on the holding bar. The yellow arrow indicates the axis of rolling of the pendulum which can only oscillate from backward to forward.

The efficiency of the stabilizer bow against rolling is high.

The pendulum rig on the opposite photograph is equipped with both the stabilizer bow and the Michael Haugrund damping device. The camera is a bit heavy (Konica Hexar = 520g) and the complete rig weight is 1160g.

The stabilizer bow by itself weights 30g.
