An electroexpulsive separation apparatus suitable for deicing of the leading edges of aircraft includes a pair of sheet-like arrays each containing in spaced-apart relationship a plurality of parallel ribbon-shaped electrically conductive members. The electrically conductive members are electrically interconnected such that any electrical current flowing in the conductive members flows in the same direction in adjacent electrically conductive members in the first sheet like member and also flows in adjacent electrically conductive members of the second sheet-like array in a direction opposite. The first and second sheet-like arrays are coextensive and superposed proximate to each other such that the electrically conductive members of the first and second sheet-like members are substantially parallel. The electrically conductive members are electrically insulated from one another. Large current pulses of predetermined magnitude, shape and duration are fed to the conductors from a power storage unit resulting in rapid and forceful separation of the first and second sheet-like arrays and other members associated therewith. The separation force for a given conductor, physical arrangement and current pulse is much greater than that of prior known devices.
Deicing apparatus comprising a first sheet-like array of a plurality of first electrically conductive members electrically insulated from one another in parallel spaced-apart relationship,
Deicing apparatus comprising at least two upper and at least two lower superposed coextensive layers of electrically conductive members, each of said layers being proximate to an adjacent layer and electrically isolated from any adjacent layer, each of said layers having a plurality of parallel, closely spaced, electrically conductive members, the layers being arranged so that the electrically conductive members in all layers are substantially parallel and overlie one another, the electrically conductive members being interconnected so that any electrical current flowing in the corresponding proximate electrically conductive members of said upper layers flows in the same direction and also flows in corresponding proximate electrically conductive members of said lower layers in a direction opposite to the flow in the electrically conductive members of said upper layers, thereby producing an electroexpulsive separation force between said upper and said lower layers of electrically conductive members, which produces a separation between said first and second electrically conductive members, the layers being joined to define a unit.
