Shmakov V. Near-wall quasistationary flow modelling in prediction of aerodynamic characteristics of flying device elements.

Object of research - elements of the flying devices in a wide range of angles of attack. The purpose of work - development of method of computation of aerodynamic characteristics of elements of flying in a wide range of angles of attack for small subsonic speeds. The scientific value of work consists of improvement of mathematical model of near-wall quasistationary flow in prediction of aerodynamic characteristics of elements of flying in a wide range of angles of attack, a method is based on combination of the modified method of discrete vortex and integral method of boundary layer characteristics predictions, got the further development of method of calculation of parameters of flows in the field of a nonviscous flow by the modified method of discrete vortex and the method of boundary layer characteristics predictions, based on integral correlations at the modeling near-wall quasistationary flow. Practical value of work - the developed method allows modelling near-wall quasistationary flow and predicting in non-stationar statement aerodynamic characteristics of elements of the flying; a method allows to conduct researches of influencing of geometrical and kinematics parameters on aerodynamic characteristics of elements of flying in a wide range of angles of attack; the results of researches of influencing of geometrical and kinematics parameters on aerodynamic characteristics of elements of flying can be used for planning of elements of flying, and also in the educational process of aviation educational establishments. The outcome of researches has used by 1 scientific investigate work, and for teaching process in Kharkov university of Air force.
