Between 1986 and 1990, a large database was compiled at AEDC from the results of a series of wind tunnel experiments investigating the aerodynamics of flow over open cavities. The database, known as the Weapons Internal Carriage and Separation (WICS) database, covered four experiments that were completed in the AEDC wind tunnels. The initial database documentation focused on the test and data, but included very little analysis of the results. The purpose of the present work is to report analysis of the cavity acoustics and trajectory data. In addition, an updated engineering mathematical model for cavity aeroacoustics is presented.

A guide for mechanical engineers to identifying flow-induced noise and vibration sources within machinery that could cause catastrophic failure. Explains methods for computing frequencies for self-sustained oscillations, and presents formulae to calculate the acoustic resonant modes for ducts and cavities. Considers the general types of flow configurations that are known to produce self-sustained oscillations and includes a complete collection of models.
