CALCULATION OF THE EQUILIBRIUM COMPOSITION OF AIR PLASMA WITH PRODUCTS OF ABLATION OF ALUMINUM FOR CONDITIONS OF BALLISTIC EXPERIMENTS

Calculations are performed for the equilibrium composition of air plas ma with products of ablation of aluminum (with due regard for the form ation of condensed Al2O3) in the region of the rear stagnation point b ehind a body for conditions of ballistic experiments (2000 < T < 4600 K, 60 < p < 600 mm Hg, 10(-4) < chi(Al) < 0.12, where Tis the temperat ure, p is the pressure, and chi(Al) is the overall aluminum fraction). The obtained results are regarded as input data for further investiga tion of complex nonequilibrium processes occurring in the far wake and appear to be of interest per se from the standpoint of the physics of low-temperature plasma seeded with aluminum.
