The need to suppress dynamic-pressure loads in open cavities represents an important problem in many aeronautical applications. Many studies have been conducted using passive and active control techniques at the leading and trailing edges of cavities that have shown some success at reducing the dynamic-pressure levels in simulated weapons bays. In this work a leading-edge fence along with a cylindrical rod, suspended in the approaching boundary layer parallel to the leading edge of the cavity, was examined. The overall pressure levels along with the spectral distribution of the surface pressure in the cavity have been shown to he altered in a favorable manner by both of these devices. Suppressing the dynamic-pressure levels in the cavity was also found to alter the correlation between sensors along the floor cavity. Although it was found that both leading-edge devices lift the shear layer away from the cavity, the manner in which it is lifted appears to play an important role in the level of surface-pressure suppression.
