Paper Abstract

The introduction of unmanned aerial vehicles is one of the most dynamic areas of civil aviation development. The great part of aircraft area their application is the performance of aerial works. For most aerial work is characterized by a small distance of aircraft from humans, animals, plants and infrastructure. Thus the influence of inductive velocity of these devices on the objects and processes of aviation operations is the topical issue. The problem of assessment of vortex trace formation and description of inductive velocity with in the flying area of multicopters, are considered in the present paper. The studies have conducted using a numerical experiment using the developed in Delphi software package. Created package provides the defined parameters of the multicopter, conditions and flight modes simulation of the formation of a vortex trace of multicopter. Visualization of the vortex trace and calculations according to the inductive velocities in the area of flight with the construction of the vector diagrams is the result of a set of interference П - shaped vortices of rotors of the multicopter, as well as addressing some immediate problems. Graph data on the spatial configuration of vortex trace and distribution of inductive velocities in the transverse planes are not uniformly distant from the multicopter on the example of a hexacopter «Odonata agro» for the accepted conditions obtained using the package are presented in the paper. General regularities and features of the formation and configuration of the vortex trace and inductive velocity distributions in the flying area of multicopters from the calculated data in the work are formulated. The results of paper can be used for estimation of parameters and the influence of the vortex trace of light multicopters on the surrounding objects and develop design solutions and modes of flight in the performance of aviation operations.
