Aircraft propulsion system assembly, comprising equipment intended to be traversed by a controlled fluid flow

Abstract

The invention relates to an assembly (15) for an aircraft propulsion system, comprising - a radial delimiting structure (31, 34, 36) for the circulation of a gas flow (12b, 10b); - equipment (45) of the propulsion system through which a fluid (P) flows; - an exhaust channel (54) of said fluid, communicating with an outlet (55) of the equipment and comprising an orifice (56) for ejecting the fluid (P) into said gas flow (12b, 10b). According to the invention, the ejection orifice (56) is at least partially delimited by a flow control element (58) through the equipment, the flow control element (58) being mounted to move in translation relative to the radial delimiting structure (31, 34, 36) so as to vary an outlet cross-section of the fluid from the ejection orifice (56).
