ABSTRACT:
This invention provides a new form of landing gear for a water plane that will minimize the time and power required to accelerate it from the at-rest, displacement-borne phase to the planing phase and takeoff phase of its operation. The landing gear of the invention is of hydrofoil type and separates the buoyant support function from the planing support function and recombines them in a way which causes them to interact, mutually assisting each other in all phases of operation, simultaneously providing a much lighter and stronger structure, having less drag and requiring less power input than devices and combinations heretofore used or proposed. Thus, the plane body is of any suitable water borne hull shape with two wings whose roots are submerged while floating to give transverse stability. The hydrofoil takes the form of a truss structure including the root portions of these wings and comprising two downwardly and inwardly inclined primary hydrofoils whose inner lower ends are spaced apart a distance wider than the plane body and connected together by a horizontal connector that may be another secondary hydrofoil. The truss is completed by two struts each connected at its upper end to the plane body and at its lower end to the junction of the respective primary hydrofoil and the horizontal connector. The submerged portion of the wings provide roll stability at rest, while the inclined primary hydrofoils provide such stability during acceleration to take-off speed.
