The NASA Langley Laminar-Flow-Control Experiment on a Swept, Supercritical Airfoil: Evaluation of Initial Perforated Configuration

By: Nasa, National Aeronautics and Space Adm

The initial evaluation of a large-chord, swept, supercritical airfoil incorporating an active laminar-flow-control (LFC) suction system with a perforated upper surface is documented in a chronological manner, and the deficiencies in the suction capability of the perforated panels as designed are described. The experiment was conducted in the Langley 8-Foot Transonic Pressure Tunnel. Also included is an evaluation of the influence of the proximity of the tunnel liner to the upper surface of the airfoil pressure distribution.
