2. wing loads are 4-6 dB greater than those for the round nozzles. At largerhn the fuselageloads areof the same orderorlowerthan thatfortheothernozzles,butthewing remains greater. Thesedifferencesarea consequenceof the strong lateral screech coupling observed for this configuration. The intense screech and impingement tones tend to increase the fuselage loading in regions away from the fountain impingementzone. The wing loadingpattern isconsistentwith the acoustic directivity of therectangularplumeflappingmode.
