A supply duct extends through the rear compartment and into the forward compartment for the delivery thereto of pressurized hot gases for distribution over the inner surface of the skin structure. A protective shroud duct surrounds the supply duct, extends from the rear bulkhead to the forward bulkhead and forms an annular space between the protective shroud duct and the supply duct. The annular space is closed off at its rear end at the rear bulkhead and throughout its length within the rear compartment by the protective shroud duct and is open at its forward end for gaseous communication with the forward compartment. A discharge duct extends from the forward compartment to atmosphere.
