- Summary
-
During development of the B-1 aircraft, an extensive cavity noise measurement and noise reduction program using wind tunnel models and evaluation on a flight-test aircraft was conducted. Substantial cavity noise reduction was achieved with retrofitted spoilers for a mach 0.6 to 1 range for the weapon bay cavity of L/D = 2.2. A substantial amount of cavity unsuppressed and suppressed data were acquired from wind tunnel models and the full-scale aircraft. Data for weapon bay cavities with internal stores and multiple open cavities was also obtained. The data acquired during development of B-1 cavity noise suppressors are correlated and compared with previously published data. The data are correlated with existing prediction techniques and modifications to the current prediction techniques, and guidelines are recommended.
