The invention provides a water pressure adaptive ship rudder which comprises a rudder stock, a rigid frame and an elastic rudder body, the rudder stock is fixedly connected with the rigid frame, the rigid frame comprises a head seal body, a middle body and a tail seal body which are sequentially connected in the chordwise direction, the middle body is of a platy structure with a plurality of hollowed-out parts, and the elastic rudder body is fixedly connected with the head seal body and the tail seal body. The elastic rudder body is provided with an adjusting cavity, the middle body is located in the adjusting cavity, the elastic rudder body comprises a connecting part arranged in the adjusting cavity, and the connecting part penetrates through the hollow part. According to the water pressure adaptive ship rudder disclosed by the invention, the elastic rudder body can generate elastic deformation, in a direct navigation state, the pressures on the two sides of the rudder body are the same, the rudder body is kept in a symmetrical airfoil shape, in a steering state, the pressures on the two sides of the rudder body are different, and the incident flow surface pressure of the rudder is greater than the back flow surface pressure of the rudder; the elastic rudder body arches from one side of an incident flow surface to one side of a back flow surface under the pressure of water flow, the section of the rudder is in a symmetrical wing shape, larger lift force is generated, and the rudder effect is effectively improved.

    本发明提供一种水压适配船用舵,包括:舵杆、刚性框架和弹性舵体,舵杆与刚性框架固定连接,刚性框架包括弦向依次连接的首封体、中间体和尾封体,中间体为具有若干镂空部的板状结构,弹性舵体分别与首封体和尾封体固定连接,弹性舵体具有调整腔,中间体处于调整腔中,弹性舵体包括设于调整腔中的连接部,连接部穿过镂空部。本发明公开的一种水压适配船用舵,弹性舵体可发生弹性形变,在直航状态下,舵体两侧受到的压力大小相同,舵体保持对称翼型,在操舵状态下,舵体两侧受到的压力不同,舵迎流面压力大于背流面压力,弹性舵体在水流压力下从迎流面一侧拱向背流面一侧,舵剖面呈费对称翼型,产生更大的升力,有效地提高了舵效。
