A study of the radiation of air-xenon mixtures in a shock layer near hypersonic models
Abstract
An analysis is made of experimental data on the luminance of air-xenon mixtures in the shock layer and in the wake of 5.35-mm-diameter spherical models flying at 2-4 km/s. The experimentally determined temperature behind the shock wave is in good agreement with theoretical calculations. New expressions are obtained relating the spectral luminance of air-xenon mixtures to incoming flow conditions for other wave lengths. The results obtained provide a way to model the spectral luminance of air near models flying at high velocities by propelling bodies in air-xenon mixtures at significanly lower velocities.
