  • Patent number: 5531405
    Abstract: A composite fabric electro-expulsive blanket is provided for shattering and removing ice and other fungible material from an accretion surface such as an airfoil. The blanket includes composite fabric upper and lower layers having a modulus of elasticity approximately between 10 to 100 million psi. Upper and lower conductor segments are positioned within the blanket so that when electrically energized, they repel one another so as to rapidly set the outer ice-accreting surface into motion. Bowed or loose stitches connecting the outer and inner layers become taut during the motion of the ice-accretion surface, thereby rapidly decelerating the surface and shattering accumulated ice thereon. Slits in the outer layer limit undesired hoop stress.
