Abstract
The problem of evaluating the maximum possible variations on position of the pressure center is considered for a given limitation of the surface variation values of the sharp cone. An integral expression for the change in the position of the pressure center for a given change in the shape of the cone is obtained. Numerical estimates of possible changes in the position of the pressure center of a sharp cone with small surface distortions at various Mach numbers are presented. The main dimensionless parameters, the “similarity criteria”, characterizing and determining the solution of problem, are indicated.
