An aircraft heated floor panel () comprising a heat-generating layer () including an electric heater () having current supply lines () and a controller () which controls the current supplied to the heater () via the supply lines () to thereby control the heat generated by the layer (). The controller () is integrated into the floor panel () whereby the panel has a stand-alone control system which need only be connected to the on-board power source of the aircraft, but can be connected to a main controller for networking or other purposes.

An electro-expulsive deicing system 114 for attachment to an airfoil 110 is comprised of a plurality of electro-expulsive elements 120 separated by a dielectric filler regions 122 all of which are disposed between a top dielectric layer 124 and a bottom dielectric layer 128. A contiguous top skin layer 116 covers the entire deicing apparatus 114.

Metal clad electro-expulsive deicer with segmented elements

A de-icer module especially adapted for installment on the inner surface of an airfoil is provided. The structural member has an outer surface upon which ice accumulates. The de-icer module comprises a support sheet delimited by a support area, a single pancake shaped separation means for developing a transient electro-mechanical separation force between the support sheet and the structural member distributed over the support area, the separation means being adjacent the support sheet, attachment means for connecting the support sheet to the inner surface of the structural member with the support sheet in close proximity to the inner surface of the structural member and the separation means sandwiched between the support sheet and the structural member. The invention provides a simplified mounting arrangement.

An electroexpulsive deicing system 18 in accordance with the present invention includes a plurality of expulsive elements 18, 22 comprised of printed circuit boards 12 having a plurality of parallel metal lines 14 formed thereon in a predetermined pattern. A plurality of conductive bridges 115 provide a fail safe aspect to the system while lowering net resistance. Adjacent expulsive elements have current flowing in opposite directions for creating expulsive electromagnetic forces between elements.

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.
