The results of the study of the bearing properties of the different wing extension with the profile of Gottingen 389 which were conducted with the help of the modified method of discrete vortexes are represented. The results of the numerical experiment with the known results of the aerodynamic testing are compared, the conclusion as for the adequacy of the chosen method of calculation of the basic aerodynamic characteristics of the different wing extension is drawn.
