Abstract
A rotary blade includes a blade body, one or more heater elements, and a temperature sensing circuit. The one or more heater elements are connected to the blade body. The temperature sensing circuit is in thermal communication with the blade body and is electrically isolated from the one or more heater elements for determining actual temperature of the rotary blade independent of operation of the one or more heater elements.
