Pressure Transducer and Computer System Providing Instantaneous Information over a Surface and Time-Dependent Predictive Ability
Abstract
A PSI 8400 pressure transducer system providing mean pressures almost instantaneously out of 48 ports and capable of responding to low frequency oscillations was purchased and absorbed by the laboratory in support of the various separation control investigations. An array of 64 Endevco surface mounted transducers capable of dynamic measurements of pressure oscillations were also bought together with National Instruments signal conditioner units. These were already used in monitoring pressure oscillations in a cavity that were generated by actuators used on wings of the XV-15 and V-22 models for the purpose of download alleviation. Four powerful PC computers and a server were purchased for data acquisition and storage, as well as for LES computations supporting the experiments being carried out in the Aerodynamic Laboratories at the University of Arizona.
