Patent

CA 2232153

An underwater vehicle (1) having a negative buoyancy comprises thrust units (4, 5) by which it can hover. Slow speed manoeuvrability while hovering is achieved by moving the position of a mass (9) fore and aft and/or side to side such as to cause the vehicle to pitch or roll and thereby vector the otherwise vertical thrust such that the vehicle is propelled in the direction in which the mass has moved.

Un engin sous-marin (1) présentant une flottabilité négative comprend des unités de poussée (4, 5) grâce auxquelles il peut rester stationnaire. Cet engin peut se manoeuvrer à petite vitesse, tout en conservant une position stationnaire, par déplacement d'une masse (9) d'avant en arrière et/ou d'un côté à l'autre, de manière à provoquer un tangage et un roulis de l'engin et ainsi guider la poussée verticale différemment de manière à ce que l'engin soit propulsé dans la direction dans laquelle la masse s'est déplacée.
