Wing-in-ground effect vehicles and methods of control
A craft includes 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.

Seaplane electric thruster drive system for lowspeed maneuvering
The present invention comprises a system which includes a novel quick release thruster mount system using one or more removable elements allowing the thrusters to be removed quickly. The present invention also comprises a novel “float compartment centric” design where no wiring to the cockpit is necessary. Redundant power units are self-contained and protected. The novel design incorporates thrust force over the surface of the water rudders improving directional control. The rudder anti lift device ALPB allows the rudders to remain in the water while reverse or braking thrust is applied. Control and monitoring are done wirelessly from the safety of the cockpit reducing hazard while maneuvering to avoid prop strike hazards to pilot, persons or objects. The system offers the ability to maintain positive directional control while taxing downwind resisting the inherent weathervane forces, braking, and turning maneuvers unachievable with current methods. The system differs from any prior art due to the aft location of drive components, method for deployment, and the fact that the drive system does not mount directly to the float itself but rather the water rudders. These forces are marginal in comparison to what is needed when one takes into consideration the Moment and Arm location of the force and the smaller lightweight thrusters do more work with less effort.

Notched hydroplane surface for aircraft floats
An amphibious aircraft includes two floats, each having a front hull and an elevated rear hull with a step between the two. Each float also has a retractable main landing gear with a main wheel. The step and the main wheel are placed strategically close to each other to provide readily controllable landings and takeoffs from water or land. To achieve such close placement of the step and the main wheel, a clearance notch in the front hull, near the step, provides space into which part of the main landing gear can extend when the main wheel descends to a deployed landing position. The size of the notch is sufficiently small to have an inconsequential effect on the front hull's ability to hydroplane. In some examples, a colored portion of the main landing gear protrudes above the float to provide a visual indication of when the main wheel is retracted.
