Integral aerodynamic layout of an unmanned aerial vehicle
Journal Title: Механіка гіроскопічних систем - Year 2018, Vol 0, Issue 36
Abstract
The study is devoted to determining the influence of various layouts parameters of the UAV on its basic aerodynamic characteristics: the maximum value of aerodynamic perfection, the characteristics of longitudinal stability and bearing properties, depending on the considered scheme and the center of gravity position. The simulation of the computational aerodynamics methods (panel-vortex method) of the modeling models calculation of an unmanned aerial vehicle layout with different positions of the center of gravity and the angles of balancing bodies is performed. Aerodynamic characteristics are obtained, ananalysis of aerodynamic perfection and criteria of static longitudinal stability for different layout schemes is performed. The estimation of static longitudinal stability at different positions of the center of gravity is carried out. According to the results of the aerodynamic characteristics mathematical modeling, it has been established that canard system with the foreplane raised above the wing surface is the most suitable design for the unmanned aerial vehicle layout. The use of the foreplane raised above the wing surface in the UAV allows to remove the canard vortex trace from the wing significantly increasing the maximum value of the КМАХ layout and ensuring the smooth nature of the landing process. The application of such layout also contributes the reduction of the wing aerodynamic loads due to the favorable local angles of attack on the wingspan.
