Abstract: An ice protection system for an aircraft includes one or more heaters configured to be coupled to a surface of a wing of the aircraft. The ice protection system also includes a controller configured to, in response to a first determination indicating presence of an icing condition, determine a setpoint temperature for a first location of an outer surface of the wing configured to be heated by a heater of the one or more heaters. The controller is also configured to control power provided to the heater based on the setpoint temperature. The setpoint temperature for the first location is determined to cause a second location of the outer surface of the wing, which is heated by the heater and is located at a particular distance from the first location, to remain above a threshold temperature based on a projected temperature profile of the outer surface heated by the heater.

Abstract: An anti-ice system is disclosed, including an airfoil structure having a leading-edge portion facing a wind direction. The airfoil structure includes an outer skin and an inner skin which form a plurality of channels, each channel having an air inlet and an air outlet. An air delivery duct inside the airfoil structure extends transverse to the wind direction and has a plurality of openings directed toward the air inlets of the channels. A heat exchanger is configured to provide hot air to the air delivery duct.
