Three-Dimensional Test Experience with a Transonic Adaptive-Wall Wind Tunnel.
Abstract
A square 9-inch wind tunnel with solid sidewalls and flexible upper and lower rod walls capable of 3-D contouring was used to test an axisymmetric and a winged lifting model at M=0.50 to 0.95. The simple, direct analytical method for wall contouring uses the model geometry for solid blockage and iterative model force data to adapt for lift and for wake blockage. Solid sidewall effects and the convergence of the adaptation scheme are evaluated. Linear and nonlinear theory for solid blockage is compared. Interesting comparisons are also made between 2-D and 3-D wall contouring. (Author)
