ABSTRACT:
A wind tunnel having a plurality of walls surrounding a test section. The walls are provided with a plurality of longitudinal slots. A channel is formed behind each slot. Each channel contains a flexible channel bottom. The shape of the flexible channel bottom may be modified by adjustment devices. The influence of the walls on air flow is thereby decreased and made easier to compute. The influence of the walls on the testing of models is reduced, wind tunnel simulation is improved, and a more accurate and reliable computation of residual influences is provided.
