Summary/Abstract: The article is devoted to the study of the geometric laws of intersection of angle shock wave formed during supersonic flow around two axisymmetric solids. An analysis of such an experiment is given by the method of processing photographs (video frames) by the parameter of image intensity. This method allows determining with high accuracy the angle of inclination of shock waves and subsequently identifies the contact points of the shock wave with the surface of the models. The proposed approach to the geometric analysis of supersonic flow around two solids makes it possible to look differently at the interference of shock waves and evaluate the qualitative and quantitative processes that occur during their interaction.
