Abstract (en)

[origin: CA3085422A1] A method for controlling the buoyancy of a submarine vehicle (1) such that it substantially has a predetermined target buoyancy Fc when it is submerged in a volume of liquid delimited by a first surface and a second surface along a vertical axis (z), the method comprising: - starting from an initial buoyancy of the vehicle which maintains the vehicle at the level of the first surface (S), a first step (100) of modifying the density of the vehicle (1) such that it approaches the second surface, the first step being implemented until a second step (200) of detecting the crossing, by the vehicle (1), of a predetermined non-zero distance threshold (SD) with respect to the first surface (S), along the vertical axis, then a third step of modifying the density of the vehicle (1) until the vehicle has substantially the target buoyancy.
