Orlovs'kyj M. Procedure of calculation of nonlinear and nonstationary aerodynamic characteristics of body profiles in interaction with turbulent streams

Object of research - lifting surface and power plant stream. The purpose of work - development of procedure and conducting investigations on calculation of power plant stream influence on aerodynamic characteristics of body airfoils. Modified method of discrete vortexes as a numeral method is used. The Scientific significance of work: the method of calculation of two-measured configurations stream-liming in accordance to bodylines was developed. The method of approximation of circulation on body surface was worked out. Besides, new method of designing of trajectories of liquid particles moved in space was proposed. The practical significance of work consists of development: recommendations about discretization the calculated profile surfaces; recommendations how to choose optimal geometric parameters characterized a position of power plant pods relatively to wing section. The outcome of researches has used by aviation design bureau "Vzlet" and for teaching process in Kharkov Pilot Institute of Airforc e.
