ABSTRACT:
An apparatus for deicing an outer shell includes an element comprised of shaped memory metal which undergoes a transformation from a weaker low temperature form (Martensite) to a stronger, high temperature form (Austenite) when the element is heated through its transformation temperature. The change in shape is utilized to deflect the outer shell to thereby shed ice accumulated thereon.
