Results of numerical simulation of a supersonic flow around 
spatial configurations of flying vehicles with the use of the Euler 
equations are presented. A model of a complex object was constructed 
on the basis of simpler base objects. Results of numerical solution 
of the problem on a three-dimensional flow around objects with an 
ogival-cylindrical airframe and a triangular wing with a diamond-shaped 
profile, arranged in different ways, at a Mach number M = 4.03 
and an angle of attack  =  10.1o have been analyzed. Calculation data 
were compared with the analogous data of a physical experiment.
