Book The NASA Langley Laminar Flow Control Experiment on a Swept Supercritical Airfoil

Download or read book The NASA Langley Laminar Flow Control Experiment on a Swept Supercritical Airfoil written by National Aeronautics and Space Adm Nasa and published by . This book was released on 2018-11-14 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of Mach number and Reynolds number on the experimental surface pressure distributions and transition patterns for a large chord, swept supercritical airfoil incorporating an active Laminar Flow Control suction system with spanwise slots are presented. The experiment was conducted in the Langley 8 foot Transonic Pressure Tunnel. Also included is a discussion of the influence of model/tunnel liner interactions on the airfoil pressure distribution. Mach number was varied from 0.40 to 0.82 at two chord Reynolds numbers, 10 and 20 x 1,000,000, and Reynolds number was varied from 10 to 20 x 1,000,000 at the design Mach number.

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

Download or read book The NASA Langley Laminar Flow Control Experiment on a Swept Supercritical Airfoil Evaluation of Initial Perforated Configuration written by National Aeronautics and Space Adm Nasa and published by Independently Published. This book was released on 2018-11-14 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book The NASA Langley Laminar Flow Control Experiment on a Swept Supercritical Airfoil Drag Equations

Download or read book The NASA Langley Laminar Flow Control Experiment on a Swept Supercritical Airfoil Drag Equations written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-07-13 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Langley Research Center has designed a swept, supercritical airfoil incorporating Laminar Flow Control for testing at transonic speeds. Analytical expressions have been developed and an evaluation made of the experimental section drag, composed of suction drag and wake drag, using theoretical design information and experimental data. The analysis shows that, although the sweep-induced boundary-layer crossflow influence on the wake drag is too large to be ignored and there is not a practical method for evaluating these crossflow effects on the experimental wake data, the conventional unswept 2-D wake-drag computation used in the reduction of the experimental data is at worst 10 percent too high.
