Results are presented of numerical investigations of three-dimensional 
supersonic flows in a disturbed region of jointly streamlined two 
identical bodies arranged in parallel which represent combinations 
of a cone with a semivertex angle of 20o and a cylinder 
with a fineness ratio of 5. Longitudinal flow over bodies has been 
studied numerically based on the Euler equation at a Mach number 
of incident flow equal to 4.03 and a zero angle of attack. 
The effect has been shown of the distance between the axes of models 
on the flow structure and disturbed and total aerodynamic characteristics 
of bodies. Calculated results have been compared with data of the 
physical experiment.
