The concept of a self-correcting wind tunnel with impermeable flexible walls deformed into an a priori determined shape of fixed magnitude is broadened to allow at least the magnitude of the wall shape to vary with flow conditions, e. g. , flow dynamic pressure. The compliant wall is then modeled as rigid hinged segments whose compliance is determined by attached springs. This concept allows for a much wider range of flow regimes and compliant wall characteristics at the cost of some increased complexity in mathematics.
