Abstract

To demonstrate the flow quality of the AIA transonic windtunnel, the flow around a supercritical airfoil is investigated in the adaptive wall test section. The mechanism of the wall adaption is described. The convergence of one adaption cycle is shown by means of the wall contours as well as the wing surface pressures. The shape and pressure distribution of the adapted wall is compared with results obtained in the ONERA T2 windtunnel in Toulouse. That tunnel is equipped with an adaptive wall test section of nearly the same geometry.
