Abstract
An air inlet structure which is mounted upstream of a central structure of a nacelle of an aircraft engine includes an outer partition incorporating a lip, an upstream partition defining with the outer partition a deicing compartment in the lip, and a hot air supply device to supply the deicing compartment with hot air. The hot air supply device has a hot air supply tube and a peripheral seal plate surrounding the supply tube. In particular, the hot air supply tube has an elbowed free end, and an orifice of the upstream partition allows passage of the elbowed free end according to a main axis of the supply tube. The seal plate includes a contact plate surrounding the supply tube to ensure sealing at the upstream partition.
