Аerodynamics of long thin cones with the asymmetric-shaped bluntness

The results of theoretical experimental research of pressure distribution on the surface and aerodynamic characteristics of burnt forms of flying vehicles which are modeled by convex-concave shaped bodies of revolution have been presented. Experimental investigations were conducted in the supersonic wind tunnel at angles of attack from 0 to 7 degrees and with Mach number from 2 to 4. The theoretical investigation results were obtained within the framework of the inviscid perfect gas model using S. K. Godunov's relaxation method of the first order accuracy on independent variables. The complex investigation demonstrated the possibility of applying the assumed physical model of inviscid flow to define the picture of stream-lining and evaluate aerodynamic characteristics during the non-interrupted stream-lining of models under investigation.
