The objective of the investigation was to determine the feasibility of a combined low-drag, high-lift boundary layer control system intended for use in the XV-11A aircraft. The XV-11A is a low-speed aerodynamic research aircraft constructed entirely of glass reinforced plastic. The combined boundary layer control system to provide full chord laminar flow over the wing surfaces in cruise flight and prevent separation of the turbulent boundary layer under conditions of high lift coefficients in the approach configuration will utilize distributed suction over the wing surfaces with the porosity provided by rows of closely spaced suction holes. The evaluation of the laminar system was accomplished on a glove section installed on the wing of a TG-3 glider.
