Sonar aerial for multi-directional transmission and reception
The sonar aerial (1) comprises a number of assemblies which are preferably identical, each comprising a piezoelectric motor and a bell fixed to a common counterweight (9). The counterweight is a cylindrical shape about an axis (ZZ1). The longitudinal axes of the separate assemblies are coplanar and...

| description | The sonar aerial (1) comprises a number of assemblies which are preferably identical, each comprising a piezoelectric motor and a bell fixed to a common counterweight (9). The counterweight is a cylindrical shape about an axis (ZZ1). The longitudinal axes of the separate assemblies are coplanar and radial w.r.t. the central axis of the cylindrical counterweight. The outer surfaces of the individual elements are coated with an electrically insulating and sealant layer (5). This may be a moulded rubber layer. Each device may also include a baffle near to the transducer, the baffle being made of a light, cellular material.
La présente invention est relative à un perfectionnement apporté aux antennes sonar. Une antenne sonar 1 comporte une pluralité d'ensembles 2 piézoélectriques sensiblement identiques fixés à une contre masse 9 commune de forme générale cylindrique d'axe ZZ1; les ensembles pavillon-moteur s'étendent selon des axes longitudinaux coplanaires radiaux; la contre masse est munie d'un évidemment 11 qui peut être rempli d'un gaz, et est reliée électriquement aux électrodes de masse 8a des transducteurs Le domaine technique de l'invention est celui de la fabrication de transducteurs accoustiques sous-marins. |
