More Information
Summary:The marine elastic rudder 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 sealing body, a middle body and a tail sealing body which are sequentially connected in the chordwise direction, the elastic rudder body comprises a shell and a filling body, the shell is connected with the head sealing body and the tail sealing body, and the filling body is connected with the shell. A containing cavity is defined by the outer shell and the middle body, and the filling body is arranged in the containing cavity; and when the rudder is in a steering state, the elastic rudder body on one side of the incident flow surface of the rudder is stressed to contract, and the elastic rudder body on one side of the back flow surface of the rudder is stressed to expand. During direct navigation, the section of the rudder blade is in a symmetrical airfoil shape, and resistance is small; during steering, the section of the r
