Abstract

An aircraft anti-fogging/frosting structural cabin window assembly is presented that includes a structural cabin window containing a transparent area and a non-transparent area; an electrically-conductive transparent heating film (THF) component disposed along the transparent area of the structural cabin window, the THF component configured to generate thermal energy in response to a supplied electric voltage from an aircraft power source; and an electrically-conductive positive temperature coefficient (PTC) ink component disposed along the non-transparent area and electrically-connected in series to the THF component, in which the PTC ink component is configured with an electrical resistance that varies with ambient temperatures. And, in response to temperatures exceeding a threshold temperature value, the electrical resistance of PTC ink component increases to a level that substantially reduces the electrical power supplied to the THF component to prevent overheating of the structural cabin window by the THF component.
