FAA JT3D QUIET NACELLE RETROFIT FEASIBILITY PROGRAM. VOLUME II. ADDENDUM A. MODEL AND FULL SCALE PLUG NOZZLE TESTS

Previous tests of plug nozzles (documented in Volume 2 of this report) resulted in conflicting evidence of acoustic suppression. Model scale plug nozzles provided significant jet noise suppression; limited or no noise suppression was observed during tests of full scale plug nozzles. The tests reported in this addendum were performed to identify the reason for noncorrelation between model and full scale acoustic results.
