PECULIARITIES OF PHOTOIONIZATION ABOUT HIGH-SPEED AIRCRAFTS
In the paper the formation of air photoionization aura ahead a shock wave about entering into the Earth’s atmosphere with a speed ~12 km/s aircraft is considered. The approached model of this effect based on the analysis of corresponding experimental data is presented. At application of this model, calculations of nonequilibrium viscous shock layer thermophysical parameters were used at flight altitudes 40÷80 km. Data on shock layer and photoionization aura plasma influence on electromagnetic waves reflection and absorption processes in different frequency ranges are obtained.
