The invention relates to a naturally-energy-driven wing-
rudder linkage long-endurance twin-
hull unmanned boat, and belongs to the field of unmanned boats. The naturally-energy-driven wing-
rudder linkage long-endurance twin-
hull unmanned boat comprises a twin-
hull sheet body, four wave swinging hydrofoils, wing-
rudder linkage mechanisms, hydrofoil mounting plates, a solar panel, a wind generator and a fan bracket. Two of the swinging hydrofoils are arranged at the bow and two of the swinging hydrofoils are arranged at the
stern, and the swinging hydrofoils are arranged side by side in the widthdirection of a hull. The arrangement method overcomes the structural
weight gain burden when the wings are greatly expanded. The front and rear hydrofoils extend towards the bow and the
stern correspondingly, so that the hydrofoils utilize the longitudinal motion of the hull in
waves and the heave amplitude is larger than the heave amplitude of the bow and the
stern of the sheet body, and thus the thrust generated by the hydrofoils is effectively improved. The wing-rudder linkage mechanisms adopt hydraulic transmission devices, the thrust of the hydrofoils on the left side and the right sideof the hull is changed by limiting the rotation range of the swinging hydrofoils on the left side and right side of the hull, a thrust difference is generated to drive the unmanned boat to rapidly rotate the bow, and when the rotation of all the hydrofoils are limited at the same time so that the unmanned boat cannot generate thrust, the unmanned boat can quickly stop, and therefore, the unmannedboat has the capability of rapidly rotating the bow and stopping in an emergency.
