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.
