Analysis of experimental and computational aerodynamic characteristics of smooth flat-face circular cylinders with the aspect ratio of 0,6 to 12,0 is given. Studies have been carried out at Mach number М∞= 4 for the angle of attack range α= 0÷90º . Effect of the cylinder aspect ratio and angle of attack on aerodynamic force coefficients in wind axes- and body axes coordinate systems is shown. A number of distinctive peculiarities in the behavior of the cylinder drag coefficient are revealed. The results obtained are presented in a form of a unique generalized dependence. The computation of some flow parameters around a cylinder has been performed within the Navie – Stokes equations, results of which are compared with the flow visualization data.
