Abstract:

Several aero-acoustic suppression devices have been evaluated which were considered feasible for installation on an F-111 aircraft for flight test evaluation. The most promising modification consists of a saw tooth spoiler mounted at the leading edge of the weapon bay. This device would be erected to a 90 degree position during the bay doors opening sequence. The spoiler is folded flush with the fuselage during all other flight conditions. Wind tunnel tests have shown that this spoiler improves the aero-acoustic environment within the open weapon bay and improves the weapon separation characteristics over the Mach range of .95 to 1.3 investigated during the drop test phase.
