Abstract

Abstract Translated from French L'invention se rapporte à un hydrophone de vitesse directif ne perturbant pas de façon notable le mouvement particulaire du fluide dans lequel il est plongé. L'invention a pour objet un hydrophone à lamelles fléchissantes (31) disposées en couronne et encastrées dans une masse inertielle (10) qui délivre un courant électrique sensiblement proportionnel à la vitesse particulaire du fluide. L'invention s'applique notamment à la réalisation d'antennes pour utilisation en acoustique sous-marine. The invention relates to a directional speed hydrophone which does not significantly disturb the particulate movement of the fluid in which it is immersed. The subject of the invention is a hydrophone with flexing lamellae (31) arranged in a crown and embedded in an inertial mass (10) which delivers an electric current substantially proportional to the particle speed of the fluid. The invention applies in particular to the production of antennas for use in underwater acoustics.
