    摘要： A craft comprises at least one hull; at least one wing configured to generate upwards aero lift as air flows past the at least one wing to facilitate wing-borne flight of the craft; a front hydrofoil connected to the at least one hull via a front hydrofoil strut and configured to generate upward hydrofoil lift as water flows past the front hydrofoil to facilitate hydrofoil-borne movement of the craft through the water; a rear hydrofoil connected to the at least one hull via a rear hydrofoil strut and configured to generate upward hydrofoil lift as water flows past the rear hydrofoil to facilitate hydrofoil-borne movement of the craft through the water; and a control system. While the craft is hydrofoil-borne, the control system is configured to facilitate transition of the craft from hydrofoil-borne operation to wing-borne operation via a process comprising: while the upwards aero lift generated by the at least one wing is below a threshold lift, controlling one or both of the front hydrofoil and the rear hydrofoil to generate a downward hydrofoil lift that causes the front hydrofoil and the rear hydrofoil to remain at least partially submerged in the water; and after the upwards aero lift generated by the at least one wing has increased above the threshold lift, transitioning the craft from hydrofoil-borne operation to wing-borne operation at least in part by controlling one or both of the front hydrofoil and the rear hydrofoil to switch from (a) generating the downward hydrofoil lift to (b) generating an upward hydrofoil lift that pushes the craft up and out of the water.

    摘要： A system for enhanced lateral stability of an amphibious aircraft includes a buoyancy system laterally displaced from opposite sides of the fuselage of the aircraft and wingtip system having a hydrodynamic planing surface associated with each wingtip. The hydrodynamic planing surface on each wingtip prevents the submersion of an associated buoyancy structure. By supplementing the lateral stability of the buoyancy structures using hydrodynamic planing surfaces, the combined lateral width of the fuselage and buoyancy structures can be reduced without detrimentally impacting operational performance. This reduced lateral width enables the amphibious aircraft to be configured for storage and transportation on a trailer or shipping container.

    摘要： The aerodynamics of a floatplane can be improved by providing a wing suitable for mounting on a spreader bar between floats of the floatplane, mounting said wing on the spreader bar between the floats of a floatplane, and preventing the wing from rotating around the spreader bar during flight operations. In one apparatus embodiment, the invention comprises a wing mountable on a spreader bar between floats of the floatplane, a plurality of ribs spaced along the wing's axis, each rib having a recess suitable for accepting the spreader bar, and torque-restraining means to prevent the wing from rotating around the spreader bar.
