In this paper, the severe aerodynamic heating phenomenon in the cabin with high-altitude reentry into the atmosphere is investigated. The three-dimensional chemical unbalanced Navier Stokes equations are numerically solved by simple implicit TVD difference scheme and shock-capture method. The chemical model is 7-component 1 Five chemical reaction air chemical models were used to simulate the chemical non-equilibrium flow field with cockpit spacecraft reentry altitude of 70km and velocity of 6 7km / s. The re-attack angle with cockpit spacecraft was 0 °, Distribution of wall heat flux, surface pressure and electron density at 1 0 ° and 2 0 °
