Optimization of the geometry of the glider wing taking into account statistical data

The article presents a synthesis of an optimization algorithm for an aerodynamic characteristics of a sailplane in preliminary design phase aimed at increasing average cross-country speed. The flight data of SZD-48-3 standard class FAI glider was collected and analyzed from weglide.org portal as a flight track files, saved in igc format. The general structure of an atmosphere was analyzed during cross-country flight basing on collected statistics. New integral criterion for the target function has been presented for usage in optimization routine loop. The criterion permits a reduction of multicriterial optimization problem to united parameter. 
Genetic Optimization algorithm has been selected as a main optimization tool due to its ability to find global optimum of an unsmooth multidimensional target function and robustness in general. The parametrization scheme with minimal number of parameters has been presented for a wing with a complex planform. The Lifting-Line Theory and XFOIL solver implemented as a mathematical model of an aerodynamic characteristics of the wing. As a result, prospective ways for consecutive development have been revealed. In particular, application of synthesized optimization algorithm towards any other classes of aerial vehicle and introduction of airfoil to wing parameterization.
