ABSTRACT:
An adaptive wind tunnel wall system for minimizing aerodynamic wall interference for slotted or perforated wall test sections. In the present invention, a plurality of continuous or segmented flexible strips may be deflected by a number of actuators to control fluid flow from the test section to a plenum or plena surrounding the test section. The actuators move the continuous or segmented strips toward and away from the slotted or perforated test section walls along the length of the test section to easily change wall crossflow resistance.
