Abstract

See full text

The invention relates to a mixer for a bypass turbomachine, the mixer comprising a member having a sinusoidal portion at its end defining inner lobes and outer lobes, each outer lobe comprising a pair of plane radial walls spaced apart from each other in the circumferential direction and interconnected by an outer dome, each inner lobe comprising a pair of plane radial walls spaced apart from each other in the circumferential direction and connected together by an inner dome, the walls of the outer lobes being disposed to extend the walls of the inner lobes radially, the radial walls of a given outer lobe extending radially in mutually parallel directions, with these walls, when extended geometrically, defining a zone from which the axis of symmetry of the cylindrical member is excluded.
