Abstract
An ice protection system may include a blade and an electrothermal heater including a carbon nanotube (CNT) element and a metal element. The CNT element may be a CNT fabric or a CNT yarn. The metal element may be coupled to the CNT element via a metallization process, or the like. The electrothermal heater element may include an electric sheet resistivity between 0.01 and 0.5 ohms/square.
