ABSTRACT:
In a device for the suspension of a sonar acoustic base within its protection dome, two connection rods are used. These two connection rods are hinged, by one side, on the hull of the ship and, on the other side, on the acoustic base. These connection rods form a triangular system which, during the motions of the base, dictates a rotation of this base about an instantaneous center of rotation R located above the center of gravity G of the base. In this way, when the base touches the internal surface of the dome, the impact occurs as a surface-to-surface impact and not as a corner-to-surface impact. This limits the damage caused by the impacts, thus making it possible to obtain, simultaneously, a very free suspension of the acoustic base and efficient protection of the sonar dome.
