Nozzles with internal mixers and external plugs are candidates for supersonic aircraft concepts. A fundamental experimental investigation is being conducted at NASA Glenn Research Center (GRC) to assess the optimum performance of external plugs. The focus is on noise reduction potential during landing and takeoff (LTO) operation of the aircraft while maintaining optimum thrust performance. Earlier results on flow field and noise of plug nozzles were presented in the 2022 AIAA Aeroacoustics Meeting [1]; see also [2] for a review of the plug nozzle literature.
