Wind Tunnels of NASA - History of Their Contribution to Flight Science from the Wright Brothers to the Shuttle, Current NASA Facilities for Aircraft and Spacecraft Tests
This book provides comprehensive coverage of the history and accomplishments of wind tunnels, featuring a reproduction of the NASA history document, Wind Tunnels of NASA, along with a special section outlining some current NASA wind tunnel capabilities. The foreword of this important volume states: Although wind tunnels are among the most important tools of aeronautical research, these facilities have remained the least understood. Some say this is partly because the instrumentation and calibration are complicated and difficult to understand and partly because the researchers that use wind tunnels too often speak in language intended for their peers and invented for their particular discipli...
Aerodynamic Tests of an M-31 Bomb in the 8-foot High-speed Tunnel
Introduction: In connection with a study of the bomb flight path, the Materiel Command of the Army Air Forces requested the NACA to conduct aerodynamic tests of a 300-pound M-31 demolition bomb. Force tests at angels of attach from -15° to 30° were made up to a Mach number of 0.725, which corresponds to a speed of 810 feet per second at sea level. These tests were made in the NACA 8-foot high-speed wind tunnel at Langley Memorial Aeronautical Laboratory.
Numerical Evaluation of the Wake-survey Equations for Subsonic Flow Including the Effect of Energy Addition
Direct-reading tables and charts are presented for determining the drag or thrust coefficients from wake-survey measurements in the subsonic speed range. For flows wherein no energy is added, the point drag coefficient is shown to be an explicit function of the stream Mach number, the static-pressure coefficient at the wake station, and the total-pressure-loss coefficient. Values of the point drag coefficient are tabulated for a wide range of values of these parameters. Inasmuch as the tabulated coefficients (either drag or thrust) represent the point values, which are independent of the integration of the wake, the charts or tables in the form presented are general in application.
NASA's Contributions to Aeronautics: Aerodynamics, structures, propulsion, controls
Two-volume collection of case studies on aspects of NACA-NASA research by noted engineers, airmen, historians, museum curators, journalists, and independent scholars. Explores various aspects of how NACA-NASA research took aeronautics from the subsonic to the hypersonic era.-publisher description.
