Patent FR-1910-416676
Inventor location: Germany
This is a kite with support surfaces oscillating around tranversal axes, characterised by the fact that to the end obtaining automatic equilibrium in both the longitudinal and tranversal senses, the support surfaces, with their transversal axes, can turn around a common longitudinal axis of the chassis.
The connexion of the support surfaces in their rotation around the tranversal axes is such that, for a constant length of these connexions, an upwards rotation of one surface corresponds automatically with a downwards rotation of the other, though, if the length of the connexions is modified by hand, the two surfaces turn at the same angle, simultaneously, upwards or downwards.
The movable ailerons are situated at the extremities of the (lift) surfaces, such that their movements take opposing effect, in such a manner that the one turns in and the other turns outwardly, thanks to the rotation of the support surfaces around the longitudinal axis of the chassis.
The control of the movable ailerons is achieved by way of an endless cable passing through a stable pulley able to be commanded by the operator to the effect of regulating the ailerons during turns.
