Keywords: wind tunnel tests, high reynolds number, scale effect, porous boundary layer control

A method is described of using boundary layer suction in the wind tunnel to simulate aerodynamic behaviour at full scale. Comparisons between results on a model tested with suction in the ARA TWT and on one of the same geometry tested under cryogenic conditions in ETW demonstrate the feasibility of this form of simulation.
