Electre Experiments in T5

A series of 18 shots was conducted on the DLR7s Electre model in Caltech's T5 hypervelocity shock tunnel facility. The model was instrumented for both pressure and heat flux measurements. It was tested at low and high enthalpies with air, argon, nitrogen and hydrogen for test gases. The trends observed in the preliminary data seem to agree quite well with results of the numerical simulations. Problems have been identified and proposed solutions should improve the quality and efficiency of future testing under similar conditions.
