The invention provides an underwater vehicle with telescopic acoustic array rotors, and relates to the technical field of underwater operation equipment. The aircraft comprises an aircraft body and an acoustic array rotor unit arranged on the aircraft body, wherein the acoustic array rotor unit comprises a cantilever bracket, a first driving mechanism, a sensor supporting body and an acoustic signal receiving sensor. According to the underwater vehicle with the telescopic acoustic array rotor wings, in the navigation mode, the cantilever support is swung through the acoustic array rotor wing unit to be attached to the vehicle body, so that the flow resistance of the underwater vehicle is reduced; a navigation mode is switched into a detection mode, the cantilever support is swung through the acoustic array rotor wing unit so as to be in a vertical posture relative to the vehicle body, the acoustic signal receiving sensors are distributed in a transverse large-span mode, the transverse receiving distance of the acoustic signal receiving sensors is increased, and the acoustic signal receiving sensors are arranged in the longitudinal direction of the sensor supporting body. Therefore, a larger acoustic aperture and array gain are obtained, and the detection precision is improved.
本发明提供了一种声阵列旋翼可伸缩的水下航行器,涉及水下作业设备技术领域。本发明包括航行器本体和设置于航行器本体上的声阵列旋翼单元,所述声阵列旋翼单元包括悬臂支架、第一驱动机构、传感器支撑体和声信号接收传感器。本发明的声阵列旋翼可伸缩的水下航行器,航行模式时,通过声阵列旋翼单元将悬臂支架摆动以贴合航行器本体,以减少水下航行器的流阻;从航行模式切换为探测模式,通过声阵列旋翼单元将悬臂支架摆动以相对于航行器本体呈垂直姿态,声信号接收传感器沿着横向大跨度分布,增加声信号接收传感器的横向接收距离,并且声信号接收传感器沿着传感器支撑体的纵向布置,以获得更大的声学孔径和基阵增益,以提高探测精度。
