DATA ACQUISITION AND REDUCTION FOR THE UVA SUPERCONDUCTING MAGNETIC SUSPENSION AND BALANCE FACILITY

摘要

The problems associated with data acquisition and reduction in the U.Va. superconducting magnetic suspension and balance facility are similar to those in free-flight ranges (or tunnels). The model undergoes a "Quasi-six-degree-of-freedom" motion which must be monitored both in position and angular orientation from which The aerodynamics must be inferred. The data acquisition problem is made more difficult because geometric constraints prevent direct visual access to the model in the Mach 3 wind tunnel. The methods, accuracies and problems associated with the acquisition of data are discussed.
