Windtunnel Capability Related to Test Sections, Cryogenics, and Computer-Windtunnel Integration.
Abstract
Experiments in windtunnels have been the major basis for improved understanding of fluid dynamics through research and for enhanced aerospace vehicle efficiency through development since before the first powered flights. The area rule concept, the supercritical airfoil, and engine installation configurations that provide favorable interference which are presently being applied to military aircraft and fuel efficient transport aircraft were evolved through windtunnel experiments. Present windtunnel experiments on active control systems and more complete integration of the propulsion system into the aerodynamics of flight vehicles will yield the improvements in effectiveness for the next generation of aircraft. Confidence that windtunnels are expected to continue to contribute to such advances is evidenced by the construction of the new large subsonic tunnel capabilities in Europe and in America, the construction of the cryogenic National Transonic Facility in America, and the planning for the European Transonic Windtunnel.
