Supporting device of underwater acoustic array

Abstract

The invention discloses a supporting device of an underwater acoustic array. The supporting device comprises a supporting fin and a transducer. The horizontal section of the head of the supporting fin is arc-shaped, and the width of the horizontal section of the tail of the supporting fin is gradually reduced from a bow to a stern till that the tail of the supporting fin forms a tip. The maximum widths of the sections of the head and the tail are consistent, and the whole horizontal section of the supporting fin is symmetrically arranged along the central axis of the horizontal section; and the transducer is fixedly connected to the lower end of the supporting fin, the upper surface of the transducer is completely matched with the lower surface of the supporting fin, and the lower surface of the transducer is in a downward-protruding streamline design. Therefore, the section width of the supporting device under the same requirement is reduced to reduce the resistance area to water flow, the water flow smoothly bypasses the supporting device, the resistance generated by the supporting device to the water flow is reduced, the resistance cannot be obviously increased under the condition that the acoustic function requirement is met, generated cavitation bubbles are fewer, and the function requirement of acoustic equipment can be better met.

Description

technical field [0001] The invention relates to the technical field of ship appendages, in particular to a supporting device for an underwater acoustic array. Background technique [0002] The acoustic array is to meet certain acoustic performance, and the transducers are installed on the array frame according to certain rules. Common base arrays are mostly blunt bodies, which will inevitably increase resistance when installed on a ship, especially when multiple arrays are required to complete the task. For some special-purpose high-speed ships, the structure of the base array Both the design and the overall size will have an impact on the speed of the ship. Therefore, it is of great significance to design a type of array support fin that can not only meet the acoustic function requirements but also increase the resistance little. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned technical deficiencies, and propose a...
