Abstract

Bei einem Torpedosonar mit konturkonformer Anordnung der elektroakustischen Wandler (e) sind auf dem Torpedobug vier Wandlerzonen gebildet, nämlich eine kreisförmige Scheitelbereichszone (f), eine sich anschließende Ringzone (g), zwei seitliche Übergangszonen (h) sowie zwei den Übergangszonen folgende, sich bis zum Großkreis des Torpedobugs erstreckende seitliche Längszonen (i).

Figure 00000001
In a torpedo sonar with contour-conforming arrangement of the electroacoustic transducer (e) four transducer zones are formed on the Torpedobug, namely a circular apex zone (f), a subsequent ring zone (g), two lateral transition zones (h) and two following the transition zones, up to the great circle of torpedo bow extending lateral longitudinal zones (i).
