Abstract
Results of experimental measurements of aerodynamic forces acting on a finite-size cylindrical body in a compressible flow are reported. The flow around a transversely aligned cylinder and the influence of yaw angle variation in the interval β = 0 - 9° are studied. For each position of the cylinder, several locations of the blowing hole along the cylinder radius are considered. The force measurements are performed with the use of strain gauges. The changes in the drag force, lift force, yaw moment, and roll moment are investigated. New experimental data are obtained in the study on the influence of blowing on changes in aerodynamic cha-racteristics of the finite-size cylindrical body in a compressible flow. The data are analyzed and interpreted.
