PULSED ELECTROTHERMAL ICE PROTECTION SYSTEMS WITH COATED HEATING SUBSTRATES

摘要

An aircraft ice protection system includes a heating substrate with a coating in intimate thermal contact with the heating substrate. The thermal effusivities of the heating substrate and the coating are different from one another for interference of thermal waves reflected from the coating with thermal waves generated in the heating substrate. A pulse generator can be operatively connected to the heating substrate to convert pulsed electrical power from the pulse generator into thermal energy for ice removal or prevention.

1. An ice protection system comprising:
a self-heating substrate; and a coating in intimate physical and thermal contact with the self-heating substrate, wherein the thermal effusivities of the self-heating substrate and the coating are different from one another for interference of thermal waves reflected from the coating with thermal waves generated in the self-heating substrate.
