The invention discloses a towed body, which belongs to the field of underwater carriers, and comprises a vertical flat shell, the shell comprises a transverse shell and a vertical shell, the upper end of the vertical shell is connected with the left end of the transverse shell, the right end of the transverse shell is provided with a tail wing, the two sides of the lower part of the vertical shell are respectively provided with a head wing, the transverse shell is internally provided with a first accommodating cavity, and the transverse shell is internally provided with a second accommodating cavity; underwater control equipment is arranged in the first containing cavity, a second containing cavity is formed in the vertical shell, and a transducer is arranged in the second containing cavity. Three-point moment balance is formed by towing force applied to the towing cable connecting accessory through the two head wings, the tail wings and the towing cable, attitude balance can be greatly improved, the shell is in a concave-convex streamline shape, flow resistance of a towed body is greatly reduced, the shell is conformal with low-frequency underwater acoustic transducers with various section forms, the application range is wide, and the low-frequency underwater acoustic transducer is suitable for being used in underwater acoustic transducers. The utilization rate of the internal space is obviously increased; by adopting the transducer array, the acoustic loss can be reduced, and the acoustic power and the acoustic radiation capability can be improved.
本发明公开了一种拖体,属于水下载具领域,其包括竖向为扁状的壳体,壳体有横向壳体和竖向壳体,竖向壳体的上端与横向壳体的左端连接,横向壳体的右端设置尾翼,竖向壳体的下部两侧分别设置首翼,横向壳体内开设第一容纳腔,第一容纳腔内设置水下控制设备,竖向壳体内开设第二容纳腔,第二容纳腔内设置换能器。本发明通过两个首翼、尾翼和拖缆施加给拖缆连接附件的拖力形成三点力矩平衡,可极大的提高姿态平衡性,本发明的壳体采用凹凸面流线型外形,使得拖体流阻大大的降低,壳体与多种剖面形式的低频水声换能器共形,应用范围广,并使得内部空间使用率显著增加;本发明采用换能器阵列,能够减小声损耗、提高声功率和声辐射能力。
