Abstract (en)
[origin: FR2793887A1] To increase the stability of the balloon during ascent a unique surface projection is used as an aerodynamic obstacle. This projection is fixed to the balloons envelope so that any aerodynamic force acting on it transmits itself to the balloon. The projection is placed on the upper part of the balloon on the upper hemisphere whilst being separated from the pole and the equator by so as to prevent air currents from sticking to the balloons surface at its lower hemisphere.
