The effect of tailcone shape on hot streak phenomena and infrared signature of serpentine nozzle with aft deck is studied. For the cases without engine swirl, the hot streak area on the nozzle wall and the infrared signature level increase with the increase of the tailcone surface curvature. The research results can provide guidance for the thermal management of serpentine nozzle.
