A Proposal for Aerodynamically Actuated Self Streamlining Subsonic Wind Tunnel Walls.
Abstract
An arrangement is described which ensures that solid flexible two dimensional subsonic tunnel walls will automatically and continuously assume a shape approximating an unconstrained streamline under the action of a model pressure field. Such a tunnel wall would minimize wall interference. Each wall consists of a streamwise tensioned membrane with a series of pressure tappings. These pressure tappings communicate with a number of flexible bellows which apply appropriate local forces to the membrane. Methods covering the extension of this concept to a three dimensional configuration are also discussed. (Author)
