Abstract
Experimental investigations were carried out on a 150mm chord NACA 0012 aerofoil in the NALls O.3m Trisonic Wind Tunnel with its transonic liners set at a open-area-ratio (OAR) around 2%. These tests confirm the earlier conclusion, derived from tests on a BGK (supercritical) aerofoil, that a 2% OAR for this tunnel produces distribution free, correctable results in the transonic regime, upto Mach number of about 0.8. As a support to the conclusion comparisons are also presented with the results of NPL (England).
