Abstract
An air inlet cowl for a jet engine, particularly an aeroengine, includes a leading edge deicer, a hollow leading edge defining an internal peripheral chamber, closed by a first internal partition, and an exhaust orifice, in the leading edge, connecting the internal chamber with the outside. The cowl further includes a pressurized hot air feedpipe for being connected, at its rear end away from the leading edge and passing through a second internal partition, to a pressurized hot air circuit and, at its front end toward the leading edge, to an injector of pressurized hot air into the internal chamber, a protective internal casing functioning with the first and second internal partitions to define an isolation volume enclosing the feedpipe, and an air extraction opening, in the first partition, to place the isolation volume in communication with the internal peripheral chamber. The area of this extraction opening is such that, in the event of damage to the feedpipe, the elimination of pressurized hot air in the isolation volume does not impair the protective internal casing and the injector injects into the internal chamber a pressurized hot air flow rate at least equal to 50% of the …
