According to the current scheme with the equivalent half-bottom surface, the subsonic streamlining of the axisymmetric bodies with the separation line located in the bottom cut area is examined. Recommendations have been made to improve the calculation method in the case of non-zero angles of attack. The estimated ratios of the technique are adapted to use the method of discrete vortexes. Detailed data on the distribution of speed and pressure on the surface of the cylindrical body with a bottom cut and the head part of the liveable shape at non-zero angles of attack are presented.
