Wind vs. Wind Tunnel: The Aerodynamics of the Inlet for NASA's New, Very Large, Nonreturn-Flow Facility
Abstract
The National Aeronautics and Space Administration is currently modifying the 40- by 80-foot subsonic wind tunnel at Ames Research Center. This modified facility will go a long way toward meeting the projected need for improvements in the capabilities of ground-based aeronautical facilities. A major concern during design development has been the effect of the external wind on the quality (uniformity) of the flow in the test section of the new open-return test circuit. Wind-effects studies on model wind tunnels have developed a relatively complex inlet treatment which should assure good test-section flow quality under most wind conditions. However, the experimental program, coupled with on-site wind measurements, has also demonstrated that even a minimum treatment can ensure adequate testing capabilities in the presence of the prevailing local winds, and that test programs will not be significantly affected.
