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).


[ What is claimed is:] [1.] An air inlet cowl (9) for a jet engine for an aircraft, said air inlet cowl (9) being equipped with means for de-icing its leading edge (16) and comprising for this purpose:a hollow leading edge (16) delimiting an internal peripheral chamber (21) which is closed by an internal partition (20), said internal partition (20) being equipped with a trough-shaped duct (22) directed toward a rear of said leading edge (16) and open toward the periphery of said air inlet cowl (9);a pipe (10) which can be connected, at its rear end away ...
