  • Publication number: 20240417081
    Abstract: The present disclosure provides for ice protection heater assemblies, and related methods of fabrication and use. More particularly, the present disclosure provides for chordwise ice protection heater assemblies for aircraft or the like. The heater assemblies provide that the heater zones for the ice protection heater assembly are designed such that the electricity mainly flows along the chord of the aircraft component (e.g., wing). This puts the electrical connection points above and below as well as behind the stagnation point of the aircraft component. The electrical connection points are thus behind the area to be protected from icing via the heater assembly.
