Abstract (en)
The invention concerns suspension devices for acoustic bases for sonars (2) inside their protective dome (9). <??>It consists in using two rods (3, 4) articulated at one end on the hull of the ship (5, 6) and at the other end (7, 8) on the acoustic base. These rods form a triangulation which imposes, during movements of the base, a rotation of the latter about an instantaneous centre of rotation (R) located above the centre of gravity (G) of the base. In this way when the base touches the inside surface of the dome, the shock is produced surface against surface and not corner against corner, which limits damage due to shocks. <??>It allows the simultaneous obtaining of a very free suspension of the acoustic base and good protection of the sonar dome. <IMAGE>
