Embodiment Construction
[0022] The overall technical solution is that the T-shaped hydrofoil is driven by a hydraulic cylinder, and the expansion and contraction of the piston rod of the hydraulic cylinder is converted into the synchronous deflection of the two flap tails through the mechanical transmission components. Because the size and connection mode of each mechanical transmission component are fixed, the expansion and contraction of the piston rod There is a quantitative relationship between the amount and the deflection angle α of the flap tail. A displacement sensor is installed on the piston rod to measure the expansion and contraction of the piston rod. By controlling the expansion and contraction of the piston rod, the semi-closed-loop control of the T-shaped hydrofoil angle of attack α can be realized. Thereby obtaining the expected pitching and heave righting moments. The present invention will be further described in detail below in conjunction with the accompanying drawings and specifi...
