Annotations languages:

Results of experiment with models of the pilotless airplane with a blade of asymmetrically varying-sweep in the echoless chamber of the Kharkov national university are presented. As a result of handling of experimental data dispersion characteristics at a various position of a blade of asymmetrically varying-sweep are received. The conclusion on negative effect of a sweep forward of a blade on a radar visibility of the airplane is drawn.
