Abstract: A craft comprises a hull, a wing, a hydrofoil, and a control system. The wing is configured to generate upwards aero lift as air flows past the wing to facilitate wing-borne flight of the craft. The hydrofoil is configured to generate upwards hydrofoil lift during a first mode of operation as water flows past the hydrofoil to facilitate hydrofoil-borne movement of the craft through the water. While the craft is hydrofoil-borne, the control system is configured to determine the upwards aero lift generated by the wing. The control system is further configured to control the hydrofoil to generate downwards hydrofoil lift to counteract the upwards aero lift generated by the wing that maintains the hydrofoil at least partially submerged in the water while the determined upwards aero lift is below a threshold lift.

Abstract: A wing-in-ground effect vehicle (100) includes (i) a main wing (104) having main wing control surfaces (118, 120); (ii) a tail (106) having tail control surfaces (126); (iii) a blown-wing propulsion system comprising an array of electric motors (116) arranged along the main wing or the tail; (iv) a retractable hydrofoil (108) configured to operate in: (a) an extended configuration in which the retractable hydrofoil extends below a hull (102) of the vehicle for submersion below a water surface and (b) a retracted configuration in which the retractable hydrofoil is retracted at least partially into the hull of the vehicle; and (v) a control system configured to maneuver the vehicle, based on a position, orientation, and velocity of the vehicle it has determined, by (i) causing a change in orientation of the retractable hydrofoil when the retractable hydrofoil is operating in the extended configuration, and (ii) causing a change in orientation of the main wing control surfaces and tail control surfaces when the retractable hydrofoil is operating in the retracted configuration.
