Abstract

Hüllkörper sind mechanischer und akustischer Schutz für eine Hydrophonanordnung. Durch Formgebung und Materialwahl werden Strömungsgeräusche vermindert, Kavitation vermieden und akustische Transparenz für Wasserschall erreicht. Der neue Hüllkörper soll gleichzeitig eine Abstrahlung von Störschall vermeiden, der durch Körperschall vom Trägerfahrzeug erzeugt und auf den Hüllkörper übertragen wird. Envelopes are more mechanical and acoustic Protection for a hydrophone arrangement. By Design and choice of materials Flow noise reduced, cavitation avoided and acoustic transparency for Water noise reached. The new envelope should at the same time a radiation of noise avoid by structure-borne noise from Carrier vehicle generated and on the envelope is transmitted.

Die Wandung des Hüllkörpers ist als Schichtverbund ausgebildet aus einer oder mehreren formsteifen Schichten (60, 61) als tragendem Element und darauf und dazwischen angeordneten Dämpfungsschichten (62) für Biegewellen. Durch Materialwahl und Dimensionierung wird die akustische Transparenz für Wasserschall erzielt. The wall of the envelope is as Layered composite formed from one or several dimensionally stable layers (60, 61) as load-bearing Element and arranged on and in between Damping layers (62) for flexible shafts. By Material choice and dimensioning will be the acoustic transparency achieved for water sound.

Bug- und Kieldome sowie Seitenhüllkörper sind mit einem solchen Schichtverbund realisierbar. Bow and kield domes and side envelopes are included such a layer composite can be realized.
