Icing and de-icing of a propeller with internal electric blade heaters

James P. Lewis, Howard C. Stevens
Aug 1948

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.
