Abstract

A three-dimensional computer model of the nonequilibrium ionization aerophysics of descent moduli entering dense atmospheric layers with orbital velocity in the height range of 60–90 km is developed. A three-dimensional numerical analysis of the experimental data on the ionization of the shock layer near the surface of a hypersonic flying module having the form of a blunt-sphere cone with the flight velocity higher than 7.5 km/s at heights of 61–81 km is fulfilled. The data of the flight experiment are obtained in the framework of the RAM-C-II investigatory program. The use of a three-dimensional computer model made it possible to find the calculated data in good agreement with the flight experiment data, as well as to explain some spatial effects not considered before.
