Investingation of electric charges on bodies and in wakes for hypersonic speeds.
Abstract
Results are presented of experimental investigations of electric charging effects surrounding projectiles and their wakes, which can imitate hypersonic atmospheric reentry of meteoroids. The charges were measured in ballistic traces with special sensors. The experimental data of electric charges were obtained for any conditions, model's material, different pressure and Mach numbers. Numerical results were obtained for gasdynamic parameters and temperatures of the projectile's surface. The results of work will give knowledge about electrical processes in hypersonic flows near meteoroids and in wakes.
