A tailcone mixer for an engine, as well as a jet engine assembly, an airplane, and methods of repairing, improving operation, and retrofitting an engine. The tailcone mixer may include a main body and a plurality of lobes. The main body may include a wider forward end and a more narrow rear end and a mid-portion extending between the forward end and the rear end. The forward end is structured and arranged for attachment to an inner duct case. The rear end is closed, and the mid-portion has a first sloping contour from the forward end to the rear end. The lobes are rigidly secured to the mid-portion. Each of the lobes has an inner section and an outer section that extend from a forward section, with the forward section being adjacent the mid-portion of the main body and the inner section extending from the forward section towards the rear end of the main body while substantially following the first sloping contour of the mid-portion of the main body. The outer section extends rearwardly from the forward section and has a second sloping contour that gradually diverges from the first sloping contour of the mid-portion.
