An ice protection system comprises deicing zones each including an envelope defining an ice-protection area. Adjacent envelopes have spanwise edge regions flanking shared interzone borders. The edge regions are provided with nonlinear contours having features which project-and-recess in a direction generally parallel to the airstream direction.

An electric heater () for integration into an acoustic panel () having sound-penetrating pores () communicating with a sound-canceling medium. The heater () includes an electrically conductive layer () with resistance-setting apertures () filled with sealant (). Openings (), which contribute to the sound-penetrating pores (), extend through the sealant-filled apertures (). The acoustic panel () can be assimilated into an aircraft component, such as a nacelle inlet lip, which requires both noise-reducing and ice-protecting features.

An aircraft component includes a first segment having a first leading edge surface that extends to a first end of the first segment. The aircraft component also includes a second segment having a second leading edge surface that extends to a second end of the second segment. The second end is substantially adjacent to the first end of the first segment, and is connected to the first end. The first leading edge surface includes electrical resistance heating that extends to the first end of the first segment. In addition, the second leading edge surface includes electrical resistance heating that extends to the second end of the second segment. The electrical resistance heating is capable of providing ice protection heating immediately on either side of a juncture between the connected first and second ends.
