The contraction cone for the NAL high Reynolds number two-dimensional wind tunnel, now under construction, has been designed to ensure that the cross-sectional area is equivalent to that of an axi-symmetric type, computed based on the theory on incompressible flow contraction, to provide the desirable characteristics in the low speed regime. In this paper are described the modification procedure of the axi-symmetric to the nonaxisymmetric contractions, and the results of the model tests conducted in a wide range of Mach numbers up to confirm the performance of the contraction cone thus designed.
