An NACA 65 one-212 airfoil of 8-foot chord was lprovided with a gas-heated leading edge for investigations of cyclical de-icing. De-icing was accomplished with intermittent heating of airfoil segments that supplied hot gas to chordwise passage in a double-skin construction. Ice removal was facilitated by a spanwise leading-edge parting strip which was continuously heated from the gas supply duct. Preliminary results demonstrate that satisfactory cyclical ice removal occurs with ratios of total cycle time to heat-on- period from 10 to 26.
