Abstract
The invention relates to lobe-type mixer tube for a bypass jet engine in which a bypass flow delivered by a fan is mixed with a hot gas stream issuing from the core engine, said lobe-type mixer tube having essentially circumferentially equally spaced gutter-shaped, radially moderately alternately inward and outward directed ducts to guide both the bypass flow and the hot gas stream, said ducts each having an end formed by an essentially plane extreme section and the respective extreme sections of some ducts when viewed in a longitudinal section extending in the direction of flow being inclined vis-a-vis the extreme sections of the other ducts. In this arrangement the radially outward directed ducts, when viewed circumferentially, alternately issue at points offset one from the other. In a preferred aspect, every other of the moderately radially outward directed ducts, when viewed circumferentially, has an extreme section which extends essentially normal to the centerline of the lobe-type mixer tube, while the extreme sections of the intervening moderately radially outward directed ducts are inclined counter the direction of flow and are therefore scarfed inversely.
