ABSTRACT	In order to investigate the capability of conducting force measurements of three-dimensional (3-D) models in NAL′s two-dimensional (2-D) wind tunnel, force measurements on AGARD calibration Model-B (Mach numbers: 0.5-1.1, Reynolds number : 3×106and 4×106). Full and half models were tested. Four different strut lengths having a circular arc cross-section and stings were used to install the full model. For the half model, a plate was installed to remove the effects of the wind tunnel′s sidewall boundary layer, as well as adding a small gap between the model and the plate to remove the effects of the plate′s boundary layer. It was shown that force measurements of 3-D models are possible in NAL′s 2-D wind tunnel, although improvements in the struts and stings are necessary to conduct tests at Mach numbers greater than 0.85.
