Inventors include Apostin, Lucie Stphanie; Combebias, Sbastien Mathieu; Debat, Alexandre Paul Raimond; Millet, Boris Jean Ren; Robert, Olivier; Tang, Etienne Yung; and Leroy, Kvin.
The application for the patent was published on June 19, 2026, under issue no. 25/2026.
Abstract: The invention relates to a drainage assembly (15) comprising a nozzle arm (11) contained in a nozzle (9) through which combustion gases flow, a drain collector (16) for collecting the fluids drained from the turbine engine (1), a Venturi ejector (17) having a primary channel (20) with a constriction (23) and a suction channel (26), and a duct (18) for connecting the drain collector to the inlet of the suction channel. The Venturi ejector is in the nozzle arm (11). The inlet and the outlet of the primary channel open into the nozzle such that a portion of the combustion gases passes through the primary channel and serves as the motive fluid for the ejector. The inlet of the suction channel is located on the side of the end of the nozzle arm that is directed towards the wall (13) of the nozzle. The inlet (21) of the primary channel (20) has a cross-section whose width corresponds to at least 70% of the maximum width (l) of the nozzle arm (11) that encloses the Venturi ejector (17).
