Aircraft wing ice protection system and method

Abstract:

An aircraft wing has a wing body with a span and a chord. A skin of the wing body has a leading edge portion with an inner surface delimiting a cavity of the wing body. A wing ice protection system includes a curved flow guide disposed within the cavity and spaced apart from the leading edge portion to define a fluid channel, A bleed air supply is operable to convey bleed air to the fluid channel. Turbulence-generating members are positioned within the leading edge portion to engage the bleed air in the fluid channel. The members are spaced apart along the fluid channel in a chordwise direction and/or in a spanwise direction. A thermal barrier may be disposed on the curved flow guide to thermally insulate the leading edge interior from the fluid channel.
