ABSTRACT:
A gas turbine engine of the type generating a hot gas stream and a fan stream includes a mixer having upstream and downstream portions which define first and second chutes for efficiently mixing the streams prior to discharge through an engine nozzle. Means are provided to selectively communicate the downstream chutes with alternate ones of the upstream chutes to cool the downstream mixer portion and reduce the infrared radiation emissions from the nozzle.
