An investigation has been made in the NACA Cleveland icing research tunnel to determine the de-icing effectiveness of an experimental configuration of an internal electric propeller-blade heater. Two atmospheric icing conditions and two propeller operating conditions were investigated in experiments with unheated blades and with heat applied to the blades both continuously and cyclically.
