New method of boundary control considers flexible aerodynamic surface as possible means of delaying transition and reducing skin-friction drag; results of analytical study on boundary-layer instability and transition in incompressible Blasius-flow over flexible surface are presented; simple flexible skin model consisting of taut membrane and elastic base is considered, and steps of computation procedure are given; potential fields of application of flexible skins would be in sailplanes, helicopters, small and medium subsonic airplanes, hydrofoils, torpedoes, speed boats, and miniature submarines.
