A CMC MIXER HAVING A STRUCTURAL OUTER COWLING

摘要

The invention relates to a mixer (100) for the separated-flow nozzles of a turbojet, for mixing a hot inner flow from the turbojet combustion chamber with the cold outer flow from the turbojet fan. The mixer includes an inner shell (120) defining a flow channel for said hot inner flow, an outer shell (110) provided around the inner shell (120) and defining therewith a flow c hannel for said cold outer flow, and a lobe structure in which the lobes (13 21, 1322) extend longitudinally from the trailing edges (HOa, 120a) of said shells. The lobe structure (130) is made of a ceramic-matrix composite mater ial and is connected to the outer shell (110) by flexible connection tabs (1 40).
