Novikov A. Propulsion propeller influence on aerodynamic characteristics of a plane lifting system

Object of research - the plane with propulsion propellers which is flowed round by a stream of an ideal incompressible liquid. The purpose of work - an establishment of laws of influence of geometrical and kinematic parameters propulsion propellers on aerodynamic characteristics of planes and their elements with use of the developed method of calculation on the basis of numerical modelling on the computer. In work as the numerical method is used panel method Morino and the modified method of discrete whirlwinds. Scientific value of work consists in development of a method of calculation aerodynamic characteristics planes with propulsion propellers which takes into account features of aerodynamic configuration of planes with the advanced mechanization of a wing, and receptions of law of change of aerodynamic characteristics of a wing and plumage at influence on them of streams from propulsion propellers on the basis of realization of parametrical researches. Practical value of work consists in development of recommendations at the choice of a rational relative positioning of bearing surfaces concerning propulsion propellers, in creation of the program of calculation of the distributed and total aerodynamic characteristics of complex combinations with coaxial and single-row propulsion propellers, including at presence of an interface and a corner of sliding, in development of the recommendation for a rational choice of parameters of digitization. The outcome of researches has used by 2 scientific investigate work, and for teaching process in Kharkov university of Air force.
