Abstracts:

Management of individual wrapping of the aircraft by influencing the course with the help of different physical mechanisms to improve the aerodynamic performance is one of the most promising and developing areas of modern aerodynamics. This paper presents the results of theoretical and numerical modeling of the influence of an electric discharge on the separation of the three-dimensional turbulent boundary layer on a thin cone. We also give estimates of separation control by local heating of the surface. The aim of this study is to control the asymmetry of the flow that occurs spontaneously around the head of the aircraft of various types at a critical angle of attack. The results indicate that the electric discharge is more efficient means of separation than the local surface heating.
