Experimental Study of Chemical Alleviation for Improving Reentry Communication,
Abstract
Chemical alleviation for improvement of reentry communication by solid ablation and liquid injection has been a practical technique. The mechanism of chemical alleviation and the method of experimental studies of simulation in an arc tunnel are discussed in this paper. Experiments are performed in the H11DF arc tunnel by two diagnostic methods which are the microwave method and the probe method. From the experiments, the effects of ablative products from the heat-protection material upon the electron concentration in the flow field and upon the transmission of the electromagnetic wave and the effect of the injection of different electrophilic reagents upon the electron concentration in the flow field are determined. This has provided the basis for selecting the heat-protection materials and determining their properties.
