The invention provides an underwater extensible active sonar aircraft, and relates to the technical field of underwater operation equipment. The underwater vehicle comprises an underwater vehicle body and an extensible detection mechanism arranged on the underwater vehicle body. The extensible detection mechanism comprises a supporting frame, a first actuator, a driving push rod, a swing rod, an extension arm, a pushing supporting rod and a sonar detection head. According to the underwater extensible active sonar vehicle, the formed active sonar receiving array is expanded through expansion of the extensible detection mechanism, a large acoustic aperture and array gain are obtained, and the horizontal omnidirectional detection function and the high-gain and high-sensitivity detection requirement are met. In addition, through a buoyancy adjusting system and a posture adjusting unit, floating and diving of the aircraft and rapid switching between a horizontal navigation detection mode and a vertical detection mode can be achieved.

    本发明提供了一种水下可扩展主动声呐航行器,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可扩展探测机构,所述可扩展探测机构包括支撑架、第一作动器、驱动推杆、摆动杆、扩展臂、推动支杆和声呐探测头。本发明的水下可扩展主动声呐航行器,通过可扩展探测机构扩展使构成的主动声呐接收阵扩展,获得较大的声学孔径和基阵增益,满足水平全向的探测功能,以及高增益高灵敏度探测需求。此外,通过浮力调节系统及姿态调节单元,可以实现航行器的上浮、下潜以及“水平航行探测模式”和“垂直探测模式”的快速切换。
