Electro-expulsive deicing system having fail safe conductive bridge means

摘要

An electroexpulsive deicing system 18 in accordance with the present invention includes a plurality of expulsive elements 18, 22 comprised of printed circuit boards 12 having a plurality of parallel metal lines 14 formed thereon in a predetermined pattern. A plurality of conductive bridges 115 provide a fail safe aspect to the system while lowering net resistance. Adjacent expulsive elements have current flowing in opposite directions for creating expulsive electromagnetic forces between elements.
