Abstract:
A mixer of a bypass turbine aeroengine according to one embodiment, includes circumferential inner and outer flow surfaces in a wavy configuration to form a plurality of lobes of the mixer. The mixer has an upstream end portion of sheet metal with a first thickness and a downstream end portion of sheet metal with a second thickness less than the first thickness.

Claim (Index 1):
A method for making a mixer of a bypass turbine aeroengine, the mixer defining a central axis extending between an upstream end and a downstream end and having circumferential inner and outer flow surfaces extending between the upstream and downstream ends of the mixer, the inner and outer flow surfaces having a wavy configuration extending toward the downstream end to form a plurality of lobes of the mixer, each of the lobes defining an internal passageway along the inner flow surface for exhaust gases flowing through the mixer and each pair of adjacent lobes defining therebetween an external passageway along the outer flow surface for a bypass air stream, the method comprising:\n a) preparing a first group of sheet metal blanks having a first thickness and a second group of sheet metal blanks having a second thickness less than the first thickness of the first group of sheet metal blanks; b) welding each one of the first group of sheet metal blanks to one of the second group of sheet metal blanks to thereby form a plurality of integrated blank-pieces each having a first portion thicker than a second portion; c) shaping the respective integrated blank-pieces into substantially identical circumferential segments of the mixer, each circumferential segment of the mixer including a section of the upstream end of the mixer formed with the first portion of one integrated blank-piece and a section of the downstream end of the mixer formed with the second portion of said one integrated blank-piece; and d) welding together the plurality of circumferential segments in a circumferential array to form the mixer in a complete configuration of a nozzle.
