Abstract

La présente invention concerne le domaine général de la lutte anti sous-marine. Elle concerne plus particulièrement le domaine des sonars aéroportés dits "sonars trempés" mis en oeuvre depuis un hélicoptère. L'invention est un système sonar déployable formé d'un élément submersible, comportant des moyens d'émission / réception acoustique formant un sonar actif, de moyens de transmission radioélectriques et de moyens autonomes d'alimentation en énergie électrique, ainsi que d'une antenne radio reliée aux moyens de transmission radioélectriques de l'élément submersible; L'élément submersible est configuré pour être accroché au câble d'un treuil équipant un hélicoptère standard ainsi que pour être mis à l'eau et récupérés au moyen de ce treuil. L'antenne est agencée sur des moyens lui permettant de rester émergée quelle que soit la profondeur d'immersion du sonar. Le sonar trempé selon l'invention peut être déployé depuis un hélicoptère équipé d'un treuil à usage général, sans nécessiter un pré-équipement spécial de l'hélicoptère.The present invention relates to the general field of anti-submarine warfare. It relates more particularly to the field of airborne sonars known as "hardened sonars" used from a helicopter. The invention is a deployable sonar system formed by a submersible element, comprising acoustic emission / reception means forming an active sonar, radioelectric transmission means and autonomous means of supplying electrical energy, as well as a radio antenna connected to the radio transmission means of the submersible element; The submersible element is configured to be attached to the cable of a winch fitted to a standard helicopter as well as to be launched and recovered by means of this winch. The antenna is arranged on means allowing it to remain emerged whatever the depth of immersion of the sonar. The hardened sonar according to the invention can be deployed from a helicopter equipped with a general-purpose winch, without requiring special pre-equipment of the helicopter.
