Aircraft air scoop icing protection systems and methods include an air duct having air inlet and outlet openings and a fairing which covers the air duct and defines an interior fairing space in which at least a forward portion of the air duct is positioned. The fairing has a forward end which surrounds the air inlet of the air duct. At least one tube is provided having an inlet end in communication with a heated air chamber associated with an airframe structure of the aircraft, and an outlet end in communication with the interior fairing space. Heated air in the heated chamber is directed through the tube to the interior fairing space so as to provide icing protection to the air duct. The air scoop icing protection systems may advantageously be employed so as to provide icing protection to air scoops associated with an aircraft engine nacelle using the residual heat from the nacelle's inlet lip primary bleed air system.

What is claimed is: 1. An aircraft icing protection system comprising a primary icing protection system to provide icing protection to an airframe structure, and a secondary icing protection system to provide icing protection to an air scoop of the aircraft, whereinthe primary icing protection system comprises,a heated air chamber; anda supply conduit for supplying heated air from a source thereof to the heated air chamber such that heat of the heated air within the heated air chamber is transferred to the airframe structure to provide icing protection thereto; and whereinthe secondary icing protection system comprises,an air duct connected to the air scoop having air inlet and outlet openings;a fairing which covers the air duct and defines an interior fairing space in which at least a forward portion of the air duct is positioned, the fairing having a forward end which surrounds the air inlet of the air duct;at least one tube having an inlet end in communication with the heated air chamber of the primary icing protection system and an outlet end in communication with the interior fairing space of the secondary icing protection system, whereinair containing residual heat that remains in the heated chamber of the primary icing protection system is directed through the tube to the interior fairing space so that the residual heat thereof is transferred to the air duct and thereby provide icing protection to the air scoop.
