A device is described in which the shape of a resistive heater material is configured to provide rapid and strong heating of a small area. The resistive heating material is heated unevenly while efficiently using power.

Spot heater

Configurations are described that provide uniform heat distribution of resistive heaters. These configurations allow successful anti-icing and deicing with relatively low applied power. One aspect involves the use of a thin film heater applied just underneath the topcoat to efficiently direct all heat to the surface, allowing anti-icing and de-icing with minimal power. This can be accomplished by employing a hybrid electrode interface, using a metal foil or metal braid that is attached to the aircraft surface with a structural adhesive that has been smoothed along the edges with metal-filled adhesive. Another aspect uses an array of heater cells created as a single sheet and a heat spreading material, provided underneath or overtop of the heater cells.
