| titleOfInvention | A variable torsional stiffness underwater tractor hydrofoil system for gliders |
| abstract | The present invention provides a variable torsional stiffness underwater tractor hydrofoil system for a glider, comprising a surface floating body vessel, a flexible cable, an underwater tractor, a hydrofoil stiffness adjustment system and a sensing unit. There are springs in the aircraft to connect with the hydrofoils. Under different initial tensions of the springs, the hydrofoils show different pitch stiffnesses and thus have different propulsion forces in waves. In the hydrofoil stiffness adjustment system, by setting a motor and a rope, pulling the movable end of the spring, and adjusting the tension force of the spring, the stiffness of the hydrofoil is controlled, and finally different propulsion forces are obtained. The present invention adopts a series structure, and can directly control the pitch stiffness of a plurality of hydrofoils through one motor. The sensing unit can sense information such as flow velocity and position and attitude, and feed the information back to the control system. The control system further controls the pitch stiffness of the hydrofoil according to the feedback information, realizes the regulation of the speed of the wave glider, and then realizes underwater traction. The best propulsion performance of the machine. |
