ABSTRACT:
An ice prevention network comprising a plurality of non-overlapping heater elements arranged in a grid along an airfoil is provided, powered by a multiphase power source, each phase powering selected heater elements that can selectively be powered on and powered off. The grid has a number of zones extending along the airfoil perpendicular to the airflow over the airfoil and a number of sections extending along the surface of the airfoil parallel to the airflow over the airfoil. Each of the heater elements is assigned to a single power phase and arranged such that an arbitrary section may be deactivated without causing a phase imbalance of more than one heating unit and such that a single zone may be activated without causing a phase imbalance of more than one heating unit.
