Quantified Unsteady Flow

"AeroArts, a small Limited Liability Company, proposes to develop an experimental test method to improve data accuracy for simulation and prediction of unsteady aerodynamics. The method will capitalize on the advantages of testing in water utilizing our newmodel support and balance system. Accurate force and moment data and flow visualization records of models undergoing motions in up to six degrees of freedom will be collected simultaneously. Effects of time delays, hysteresis and other unsteady andnonlinear phenomena will be included. These effects will be examined using parameter identification methods, both in the time and frequency domains. The method with its hardware and software will have application to markets for both military and commercialaircraft development and to education and research facilities. A significant number of other aircraft manufacturers, along with research and educational institutions around the world, have active water tunnels from different manufacturers, and thisrepresents the marketplace for the AeroArts Scorpio system. Following thorough validation of the concept in Phase II, a significant percentage of these facilities would benefit from the capability to correlate video capture with dynamic force and momentmeasurement"
