Abstract

An exhaust mixer for a turbofan engine comprises an annular wall defining a central longitudinal axis. The annular wall has an opposed upstream end and trailing edge and defines a plurality of circumferentially distributed radially undulating first lobes and second lobes arranged in a periodic arrangement. The first lobes have a first lobe trailing edge portion, which has a shortest extent and/or longest extent along the central longitudinal axis between a radially outermost point of the first lobe and a radially innermost point of an adjacent lobe. The second lobes have a second lobe trailing edge portion that is sloped along the radial direction. An axial extent of the second lobe trailing edge portion changes along the central longitudinal axis as the second lobe trailing edge portion extends radially inwards towards the innermost point of an adjacent lobe.
