An aircraft engine nacelle comprises: (a) an inlet lip and a skin having
internal and external surfaces; (b) a noise abatement structure such as
an acoustic panel located on the internal surface of the nacelle skin;
and (c) an electrically powered de-icing system located on the external
surface of the nacelle skin and in electrical connection to a power
source. A method for de-icing and abating noise from an aircraft nacelle
comprises: (a) providing a noise abatement structure such as an acoustic
panel located on the internal surface of the nacelle skin; (b) providing
an electrically powered de-icing system on the external surface of the
nacelle skin; and (c) applying an electric current to the electrically
powered de-icing system. The nacelle skin may be a perforated skin, and
the de-icing system comprises a wire mesh bonded to the external surface
of the perforated skin. The method and nacelle permit the use of noise
abatement structures such as acoustic panels for noise reduction while
advantageously avoiding detrimental high temperatures associated with
conventional de-icing systems.
