Abstract
Two recent sounding rocket experiments have obtained spectral data from 200 - 400 nm of the shock heated air surrounding the vehicle under flight conditions corresponding to 3.5 km/sec for altitudes of 40 - 70 km and at 5 km/s for altitudes of 100 - 65 km. Previous analyses of the data have emphasized modeling the radiation from the NO molecular system. The chemical kinetics of OH, a trace species in the flow, and the electronic state excitation mechanisms are simpler than those for NO. Hence the comparison between modeling and data potentially provides a clearer assessment of the key flow thermochemical processes. This paper discusses the OH flow and radiation models that we have developed, comparisons with data, and the implications of this work to ongoing NO flow and radiation modeling. Additional data from the side-viewing spectrometers from the 5 km/sec flight will also be presented and analyzed here for the first time.
