In simulating conditions for flight of spacecraft in the upper layers of the atmosphere one must model the ionization, excitation, and dissociation of the flow [1], in addition to other parameters. Modeling of these parameters is important, in particular, in investigations of sensors intended for measuring flight parameters aborad a spacecraft, tests of structural materials, and determination of the aerodynamic characteristics of spacecraft. The studies described here employ multielectrode probes, a metastable particle detector, and catalytic sensors to investigate the ionized, dissociated, and excited components of high-speed free-molecular flow in a facility [2] which models flight conditions in the upper atmospheric layers. It is shown that the degrees of ionization and dissociation, and also the metastable particle concentration in the flow, correspond to the natural values of these parameters at altitudes H = 120–200 km.
