A towed linear array test static array structure and method on a lake

Abstract

The invention discloses a static array structure and method for a towed line array lake test. The static array structure mainly comprises a towed line array; a depthkeeping rope is bundled at a certain distance along the length direction of the towed line array, a floating ball is connected to the upper part of the depthkeeping rope; a lightweight counterweight is connected to a lower part of thedepthkeeping rope; a diagonal rope is fixed on each of the depthkeeping ropes at the head and the tail of the towed line array, and a weight is added on the lower part of the depthkeeping rope; the towed line array is straightened through the diagonal ropes. The static array structure and method can realize the static array of the towed line array in the lake waters quickly, efficiently, safely and at low cost, use few floating balls to replace continuous buoyancy rods, and are low in cost; after the array is completed, normal navigation of the surface vessel is not affected, and the safety isgood; the floating balls spaced apart from each other are not sensitive to the influence of the wind, are less affected by wind and waves; the array shape is easy to adjust; and the static array structure and method have been applied and promoted in many projects in the 715 institute.

Description

Technical field[0001]The invention relates to the field of test methods, in particular to a trailing linear array lake test static array structure and method.Background technique[0002]The static array, that is, the towed linear array is deployed in a certain depth of water approximately in a straight line, which is an indispensable part of the trail on the towed linear array lake. The traditional array method requires continuous arranging of buoyancy rods on the water surface along the direction of the array, and then the towing line array is suspended under the bamboo poles with ropes and straightened. It has the following shortcomings: the total length of the buoyancy rods is equivalent to the towing line array. The cost is high; the array work includes the arrangement of buoyancy rods and the towing line array, which takes a long time and a lot of work; the buoyancy rods on the water affect the normal passage of ships and pose safety hazards; the accuracy of the array is not high...

AI Technical Summary

Problems solved by technology

The traditional deployment method needs to continuously arrange the buoyancy rods along the direction of the formation on the water surface, and then hang the towing line array under the bamboo poles with ropes and straighten it. It has the following disadvantages: the total length of the buoyancy rods is equivalent to that of the towing line array. The cost is high; the arrangement of the array includes the arrangement of the buoyancy rods and the arrangement of the towing line array, which takes a long time and a large workload; the buoyancy rods on the water surface affect the normal passage of ships, and there are potential safety hazards; the accuracy of the array arrangement is not high, which affects the test results; buoyancy The pole is sensitive to the influence of wind and waves, which is easy to cause formation distortion; formation adjustment is difficult
