TURBINE ENGINE SEPARATE FLOW MIXER

The invention relates to a turbine engine separate flow mixer (2) centred on a longitudinal axis (X-X), comprising an exhaust housing (6), a shroud (4) directly connected to the exhaust housing (6) and intended to mix the flows originating from the turbine engine, said shroud (4) comprising a metal sheet formed by a series of first and second longitudinal strips (4a, 4b) circumferentially distributed around the longitudinal axis of the mixer by circumferentially placing the second strips (4b) on either side of the first strips (4a), the first and second strips being configured to form the shroud (4) at rest and by making grooves in the shroud, the grooves being defined by an alternation of internal lobes and of external lobes. 本发明涉及一种以纵向轴线(X-X)为中心的涡轮发动机分离流动混合器(2)，包括：排气外壳(6)；护罩(4)，该护罩(4)直接连接到排气外壳(6)，并旨在混合源自涡轮发动机的流动，所述护罩(4)包括由一系列第一和第二纵向条带(4a、4b)形成的金属板，该一系列第一和第二纵向条带(4a、4b)通过将第二条带(4b)周向地放置于第一条带(4a)的任一侧以围绕混合器的纵向轴线周向地分布，第一和第二条带构造成在静止时形成护罩(4)，而在运行时形成在护罩中的凹槽，该凹槽由内部凸角和外部凸角的交替来限定。
