Features of formation of an adverse longitudinal pressure 
gradient in a supersonic flow around a carrying body with a surface 
inclined at a constant angle to its symmetry plane have been numerically 
investigated within the framework of the Euler equations. A mathematical 
model of such bodies constructed on the basis of pieces cut from the 
surface of a backward-facing hyperelliptic cone is proposed. This 
model allows one to obtain a wide variety of carrying bodies. The 
data obtained were compared with the corresponding data for equivalent 
bodies with a plane downstream face.
