Abstract

A control system for a hydrofoil characterized in that a transition from the foil-borne to the hull-borne mode of operation is initiated and the craft caused to descend or land automatically before an unsafe foil-borne roll or yaw attitude can be developed. This is achieved by providing an auxiliary electronic power source and auxiliary servo feedbacks in parallel with the main feedbacks for the control surface servos of the hydrofoil. The auxiliary feedbacks provide means for positioning the control surfaces to automatically land the craft upon the occurrence of a failure in the primary power source for the hydrofoil or some other off-normal condition.
