AIRCRAFT WING WITH ELECTROTHERMAL DEICING AND/OR ANTI-ICING DEVICE
First Claim
1. A method of removing ice build-up on a susceptible area of an aircraft;
- comprising the steps of;
heating a zone adjacent the susceptible area to partially melt the ice build-up on the susceptible area; and
after a delay, heating a zone fore of the susceptible area to provide warm runback water to the partially melt ice build-up.

Abstract
An aircraft wing (12) comprising a structural member (20) forming the wing'"'"'s leading edge skin, a Kreuger flap (16) which moves relative to the structural member (20) between a stowed position and a deployed position, and an electrothermal device (34) mounted (e.g., internally mounted) to the structural member (20). An aft portion (30) of the structural member (20) is curved inwardly to form a recess (32), and a fore portion (18) of the flap (16) fits within the notch (32) to form a joggle therebetween. The electrothermal device (34) is a deicing and/or anti-icing device which continuously provides heat to the curved aft portion (30) of the structural member (20) during icing conditions so as to prevent deployment-inhibiting ice buildup on the flap (16).

6. An aircraft wing comprising a structural member forming a leading edge skin, a flap which moves relative to the structural member between a stowed position and a deployed position, and an electrothermal device mounted to the structural member;
-
wherein an aft portion of the structural member is recessed inwardly to form a recess, and a fore portion of the flap fits within the recess;
wherein the electrothermal device provides heat to the recessed aft portion of the structural member during icing conditions;
wherein at least one anti-icing zone is positioned to prevent ice build-up that would impede deployment of the movable flap; and
wherein other deicing zones are positioned are provide warm runback flow to the at least one anti-icing zone. - View Dependent Claims (7, 8, 9, 10, 13, 14, 15, 16)
