Download or read book An Experimental Investigation of an Airfoil Optimized for High Lift written by Richard E. Walters and published by . This book was released on 1974 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental investigation was performed on an airfoil optimized for maximum lift. The airfoil shape was designed from an optimum pressure distribution using a calculus of variation technique. The purpose of the investigation was to evaluate the validity of the method of design of the airfoil, and to determine what type of differences existed, if any, in the theoretical and experimental results. The airfoil was tested at a Reynolds number approximating the design Reynolds number of 1,000,000. The airfoil angle of attack was varied in 2 deg increments from 0 deg to 12 deg. At each angle of attack, three blowing rates were used for slots installed on the model end plates. Data recorded for each test run consisted of the airfoil static pressure distribution, static and total pressures from a wake traverse, atmospheric pressure and temperature, and the tunnel temperature. Normal and chordwise force coefficients were obtained from the static pressure data. Using the true angles of attack from potential flow theory, lift and pressure drag coefficients were found. Total drag coefficients were found from the wake traverse data. Increased blowing caused the experimental pressure coefficient distributions at higher angles of attack to come into close agreement with the theoretical pressure coefficient distribution, and resulted in increased lift and decreased drag. True two-dimensional flow was not maintained at the higher angles of attack, due at least in part to the test installation. (Author).

Download or read book Design and Predictions for a High-altitude (low-Reynolds-number) Aerodynamic Flight Experiment written by Donald Greer and published by . This book was released on 1999 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: A sailplane being developed at NASA Dryden Flight Research Center will support a high-altitude flight experiment. The experiment will measure the performance parameters of an airfoil at high altitudes (70,000 to 100,000 ft), low Reynolds numbers (200,000 to 700,000), and high subsonic Mach numbers (0.5 to 0.65). The airfoil section lift and drag are determined from pitot and static pressure measurements. The locations of the separation bubble, Tollmien-Schlichting boundary layer instability frequencies, and vortex shedding are measured from a hot-film strip. The details of the planned flight experiment are presented. Several predictions of the airfoil performance are also presented. Mark Drela from the Massachusetts Institute of Technology designed the APEX-16 airfoil, using the MSES code. Two-dimensional Navier-Stokes analyses were performed by Mahidhar Tatineni and Xiaolin Zhong from the University of California, Los Angeles, and by the authors at NASA Dryden.

This book was released on 1952 with total page 852 pages. Available in PDF, EPUB and Kindle. Book excerpt: The pressres acting on the base of blunt-trailing-edge airfoils have been measured at Mach numbers of 1.25, 1.5, 2.0, and 3.1 and at Reynolds numbers from 0.2 to 3.8 million. Data are presented for 29 profiles both with laminar and with turbulent boundary layers approaching the trailing edges of the wings. The base pressure is found to be a function primarily of Mach number and the ratio of the boundary layer thickeness at the trailing edge to the trailing-edge thickness.
