Abstract : The patent is for a system for determining the collective torque resulting from a fluctuating pressure field upon a cavity subjected to aerodynamic flow, determined by mounting a plurality of high response pressure transducers about a shell in a cavity with each of the transducers located at the centroid of an area being investigated. Associated with each of the transducers are electrical signals representing each of the particular areas and signals representing the distance from the centroid of that area to the axis of interest.
