Abstract
A permanently fixed fairing is provided extending across the air duct coinciding with the opening in the air duct to the air intake of a gas turbine engine. The fairing is in the form of an airfoil vane with a high pressure concave surface and a low pressure convex surface extending between the leading edge and trailing edge of the fairing and shaped such that the leading edge portion of the fairing is in the direction of the longitudinal axis of the air duct while the trailing edge portion of the fairing is in the direction of the air intake of the engine such that the fairing will divert air into the intake. A deflecting flap is hinged to the wall of the duct in a first position for a non-icing mode whereby the flap is clear of the air duct and in a second position whereby the trailing edge of the flap is adjacent the leading edge of the fairing during an icing mode.
