Strategy for safeguarding an airship in the event of heating of its solar generator

A method for controlling a stratospheric airship comprising a nonrigid balloon equipped with a solar generator arranged on an upper part of the nonrigid balloon intended to be illuminated in flight by the sun, wherein a position of a center of gravity of the airship and stabilization of an attitude of the airship are controlled in a coupled manner by a module in said airship which controls the attitude of the airship to specifically rotate said airship by substantially 180 degrees about its longitudinal axis (AL), in response to at least one of a speed of travel of the airship with respect to surrounding air being below a first threshold (S1) or a temperature of the solar generator being above a second threshold (S2), so as to protect the solar generator from illumination by the sun, wherein the airship comprises a device for managing the position of the center of gravity of the airship, which comprises a predetermined positioning of elements carried onboard the airship, so that the center of gravity of the airship is situated between its longitudinal axis (AL) and the solar generator, and wherein the airship comprises a device for stabilizing the attitude of the airship, which comprises aerodynamic control surfaces.
