초록

A turbofan engine exhaust nozzle includes cooperating outer and inner mixers. The outer mixer includes alternating outer lobes and outer chutes. The inner mixer includes alternating inner lobes and inner chutes. Forward ends of the outer and inner mixers are spaced radially apart, and aft ends of the mixers are joined together to define an outlet of the nozzle for discharging exhaust flow.
