Abstract
Damage to the skin of the annular cowl (11) of the intake duct of a turbo-fan engine of an aircraft by exhausting on to it of hot air used within the cowl for de-icing its leading edge (10) is avoided by channelling spent air through an exhaust duct (15) to an exhaust aperture (21) in the surface of the cowl, and providing a heat shield (23) in the skin downstream of the exhaust aperture (21).
