A stratospheric airship includes a nonrigid balloon equipped with a solar generator arranged on the upper part of the nonrigid balloon intended to be illuminated in flight by the sun, the airship comprising: at least one device for managing the position of the centre of gravity of the airship; at least one device for stabilizing the attitude of the airship; and a module for the coupled control of the devices, configured to control the airship, when the speed of travel of the airship with respect to the surrounding air is below a first threshold (S1) and/or the temperature of the solar generator is above a second threshold (S2), in such a way that it rotates by substantially half a turn about its longitudinal axis (AL), so as to protect the solar generator from illumination by the sun.
A stratospheric airship comprising a nonrigid balloon equipped with a solar generator arranged on the upper part of the nonrigid balloon intended to be illuminated in flight by the sun, the airship comprising:
A method for controlling a stratospheric airship comprising a nonrigid balloon equipped with a solar generator arranged on the upper part of the nonrigid balloon intended to be illuminated in flight by the sun, wherein the position of the centre of gravity of the airship and the stabilization of the attitude of the airship are controlled in a coupled manner so that, when the speed of travel of the airship with respect to the surrounding air is below a first threshold (S1) and/or the temperature of the solar generator is above a second threshold (S2), the airship rotates by substantially half a turn about its longitudinal axis (AL) so as to protect the solar generator from illumination by the sun.
