Recently, a wind tunnel test was conducted to evaluate the separation characteristics, at M = .85 and 1.2, of eight MK-82 500 pound bombs densely packed in a cavity with an L/D ratio of 5.38. This cavity was sized to fit in the channel under the F-14 aircraft. Preliminary results indicate that the critical conditions occur at the aft end of a densely packed cavity. Furthermore, it appears that empty cavity grid test data may not be safely used to predict trajectories for conditions where several bombs are still present in the bay. An attempt was also made to apply the Influence Function Method (IFM) to a cavity environment. Although the technique shows some promise, further testing and analysis will be required before it's validity can be demonstrated.
