摘要：
The present invention relates to an air inlet cowl (9) for a jet engine. According to the invention, provided in the partition (20) delimiting the de-icing chamber (21) in the hollow leading edge (16) of the cowl is a trough-shaped duct (22) for ejecting to the outside pressurized hot air which has flowed through the chamber (21). The duct (22) is reduced in cross section by a single oblong orifice (18) made, parallel to the leading edge (16), in a part (23) that forms part of the external surface (9E) of the cowl (9).
