A mixer arrangement for a bypass type gas turbine engine is disclosed. The mixer is convoluted and generally annular and defines radially and axially extending first and second chutes adapted to receive, respectively, a hot gas stream from the engine core and a cooler gas stream from the fan duct. A pre-mixer is disposed upstream of the mixer and is also convoluted and is aligned in flow communication with the second chutes of the mixer such that the hot gas stream received by the pre-mixer is mixed with the cooler fan air stream received by the second chutes to raise the temperature of the fan air entering an afterburner section of the engine.
