Antivibration device for submerged towing of a submarine acoustic measurement base

摘要

Antivibration device for submerged towing of a submarine acoustic measurement base and in particular a long base. The antivibration device, inserted between the towing end (2) of the measurement base and the end of the towing cable (1) includes a main damper (3) composed of a flexible tube (32) provided with water circulation openings (33) along its wall and containing an electrical cable (42) which is longer than it. An additional damper (4) placed upstream of the main damper is composed of an inextensible and leaktight flexible tube (342) containing a fluid having low density compared to water and mobile masses (48) of high density which are spaced along the tube. The invention applies to systems for measuring in a marine environment. <IMAGE>
