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).
