Abstract

La tuyère (1) pour une turbomachine d’aéronef comprend une paroi (4) annulaire comportant un orifice (6) d’évacuation d’un flux d’air susceptible de comprendre des résidus d’huile ou de carburant. La paroi (4) annulaire comporte une face interne (4A) sur laquelle est fixé un convertisseur catalytique (8) qui filtre au moins une partie du flux d’air pour traiter les résidus d’huile ou de carburant. Leur traitement par le convertisseur catalytique (8) permet d’éviter les risques d’encrassement d’un échangeur ou de laisser des traces noires dans la tuyère (1) et de limiter les émissions d’hydrocarbures imbrulés. Figure pour l'abrégé : Figure 1The nozzle (1) for an aircraft turbomachine comprises an annular wall (4) comprising an orifice (6) for evacuating a flow of air likely to include oil or fuel residues. The annular wall (4) has an internal face (4A) on which is fixed a catalytic converter (8) which filters at least part of the air flow to treat oil or fuel residues. Their treatment by the catalytic converter (8) makes it possible to avoid the risk of clogging an exchanger or leaving black traces in the nozzle (1) and to limit emissions of unburned hydrocarbons.
