Abstract
A de-icing blanket and method of ice-removal from a moving object such as an airfoil comprises a center portion including a heater, and side portions flanking the center portion, each side portion including an electro-expulsive de-icing system (EEDS). The center portion is placed on the leading edge of the airfoil forwardly with respect to the side longitudinal portions such that when the airfoil is in motion, an airflow impinging on the airfoil forces water contacting an exposed surface of the center portion to flow rearwardly and to freeze on accreting surfaces of the side portions where the ice is subsequently removed by energizing the EEDS. The blanket may include a leading edge cap made of a highly polished impervious material to protect the blanket from atmospheric weathering.
