Abstract
What is proposed is an electro-impulse de-icing device for use in an airfoil of an aircraft that includes a system having an energy storage device connected via a triggering device to a set of coils each embodying a coil construction in the form of a spirally wound ribbon coil member whose planar dimension is pressed against an interior surface in the leading edge of the airfoil, and wherein the coil sets are arranged in a linear manner along the long axis of the airfoil and are energized simultaneously and sequentially via an interlocking pattern from the wing tips or from the fuselage of the aircraft with each coil set being triggered twice from about three to five seconds apart.
Claims7
A method for de-icing an airfoil of an aircraft by means of a de-icing system having an energy storage means connected via a triggering means for energizing a plurality of electromagnetic coil sets arranged in a linear array under the leading edge of said airfoil for a given span thereof, comprising the steps of
- sequentially selecting interlocking groups of said coil sets for being energized, each of said groups occupying a portion of said span of said airfoil, whereby said interlocking groups are progressively energized along said span of said airfoil,
- simultaneously energizing said coil sets in each of said groups when sequentially selected, including
- triggering each of said coil sets twice from 3 to 5 seconds apart during said energizing step.

- sequentially selecting interlocking groups of said coil sets for being energized, each of said groups occupying a portion of said span of said airfoil, whereby said interlocking groups are progressively energized along said span of said airfoil, and
- simultaneously energizing said coil sets in each of said groups when sequentially selected.
A de-icing system for an airfoil of an aircraft, comprising
- an energy storage means,
- a triggering means connected to said energy storage means,
- a plurality of electromagnetic coil sets connected to said triggering means and disposed in a linear array under the leading edge of said airfoil for a given span thereof,
- a logic circuit means connected to said triggering means for sequentially selecting interlocking groups of said coil sets to be energized by said energy storage means, each of said groups occupying a portion of said span of said airfoil, whereby said interlocking groups are progressively energized along said span of said airfoil, and
- said triggering means simultaneously energizing said coil sets in each of said sequentially selected interlocking groups.
