Аннотация:The effect of overequilibrium heating of a surface with nonuniform catalytic properties ina subsonic flow of dissociated air is experimentally studied using the VGU-4 HF-plasmatron. A temperaturejump is observed on a plate of Buran orbital vehicle heat-shield material as the flow transitionsfrom the low-catalytic area of the surface to the high-catalytic area covered with chromiumnickelspinel NiCr2O4. A temperature jump is also observed on the heat-shield tile of the Buran orbitalvehicle at the transition from the low-catalytic area of its surface to the medium-catalytic area coveredwith niobium.
