INTERACTION OF ELECTROMAGNETIC WAVES WITH THE PLASMAS OF HYPERSONIC FLOWS
Abstract
The physical, chemical, and aerodynamic aspects of the interaction between electromagnetic waves and hypersonic plasmas are briefly discussed. It is shown that the various aspects of the problem couple strongly and that essential parts of the general problem are still unsolved. The incomplete status of the basic data and the complexity of the general problem suggest experimental model testing. The number of necessary similarity parameters involved is so great that largescale models must be used in general to obtain useful data. The CAL six-foot hypersonic shock tunnel, in which models of the order of one foot in diameter may be used, is described and its performance capabilities given. The results of some recent tests are discussed. It is concluded that the performance of the tunnel is encouraging from an aerodynamic and chemical purity point of view. The communication blackout problem is considered as a problem to be studied using the CAL shock tunnel. It is shown that two useful approaches can be followed, - one leading to the gathering of test data for various configurations and the other leading to the assessment of the validity of various schemes for the amelioration of the problem.
