Acoustic nacelle inlet lip having composite construction and an integral electric ice protection heater disposed therein

An engine nacelle inlet lip includes both acoustic treatment and electric heating for ice protection. The inlet lip has a composite outer skin and a composite inner skin, with the composite outer skin having at least one integrated heater element embedded in the composite material. An acoustic cellular core positioned between the outer and inner skin acts to attenuate fan noise from the engine. Covering the outer skin and overlying the acoustic core is a perforated erosion shield having a first set of openings that pass entirely thorough its thickness. The composite outer skin includes a second set of openings such that sound waves can pass from an inner barrel portion of the inlet lip through the erosion shield, outer skin, and heater element to the underlying acoustic cellular core.

Modular anti-icing/de-icing device for an aerodynamic surface

A anti-icing / de-icing device for an aircraft wing includes at least one aerodynamic surface, e.g. a rotorcraft blade or an airplane wing, the aerodynamic surface possessing at least two anti-icing / de-icing modules 17, with each module 17 being provided with a respective heater element 54. In addition, the heater elements 54 of the modules 17 are powered electrically by a common electrical power supply member 1, each anti-icing / de-icing module acting against icing in its own zone independently of the other module(s).
