Two-Dimensional Adaptive-Wall Experiments
Abstract
Experiments conducted in the Arnold Engineering Development Center (AEDC) Propulsion Wind Tunnel Facility Aerodynamic Wind Tunnel (1T) were part of a continuing program to develop adaptive-wall technology for the elimination of wall interference in transonic wind tunnels. The test section arrangement consisted of uniformly variable-porosity porous walls enclosed by a variable pressure plenum. Two subplena were attached to both the top and bottom walls in th region of the test model location. Two subplena locations were investigated. One location was established by test section boundary flow-angle criteria, and the other by test section boundary pressure criteria. The subplena location was shown to significantly affect the results. The test model was a six-percent solid blockage, two-dimensional NACA-0012 wing. The experiments were conducted for both lifting and nonlifting conditions including those conditions for which the supercritical flow regions extended to the test section boundary.
