Investigation of the influence of controls on the flow around the UAV model

Abstract

Studies of the flow structure were performed on a trapezoidal UAV model. The experiments were carried out in a wind tunnel at subsonic speeds. The method of soot-oil visualization was used to obtain a picture of the flow around the model. The experiments were made at different angles of attack, as well as at different deflections of the ailerons on the model. The peculiarity of the work is that the experiments were conducted at full-scale (flight) Reynolds numbers.
