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

The results are given of the calculations of the equilibrium compositi on of air plasma with products of ablation of Teflon, performed for co nditions of ballistic experiments in the region of the rear stagnation point behind a body (2000 K < T < 5600 K, 60 torr < p < 600 ton, 10(- 4) < chi(add) < 0.20, where T is the temperature, p the pressure, and chi(add) is the number of moles of C2F4 in a mixture with 0.8 moles of nitrogen and 0.2 moles of oxygen -0.8N + 0.20 + chi(add)). The obtain ed results provide the input data for further investigation of complex nonequilibrium processes occurring in the far wake and are of interes t per se from the standpoint of the physics of low-temperature plasma seeded with Teflon.
