Results of experiment with models of the pilotless airplane with a transformable wing in the wind tunnel Т-1 of the Kharkov university of Air Forces and the echoless chamber of the Kharkov national university are presented. As a result of handling of experimental data relations of drag coefficient, lifting power, aerodynamic quality, the dispersion characteristic are received at various positions of a transformable wing. On the basis of the analysis of the received relations position versions of a transformable wing concerning a fuselage (optimum by criteria «the maximum lift-to-drag ratio», «the minimum drag», «the minimum radar visibility») are determined.
