| Abstract: | The range equipment for the investigation of the hypervelocity aerodynamic properties and flow field of explosively formed projectile(EFP) models is described.The technique of the full scale interferogram recording is briefly reported.The procedure of the radial density distributions reconstruction is discussed.The aerodynamic drag of different models at zero angle of attack in the experiment is calculated using the simplified procedure.The qualitative considerations about aerodynamic stability for various EFP forms are proposed.The fundamentals of the numerical calculation technique applied to research of hypervelosity flight characteristics of composed bodies are formulated. |
