The extremely thin and elongated wing configuration of the transonic truss-braced wing (TTBW) model posed significant challenges to researchers testing the concept in NASA Ames Research Center’s Unitary Plan transonic wind tunnel. The main focus for the NASA/Boeing test team during the recently completed high-speed evaluation was to collect pressure data around the junction of the wing and the slender supporting strut. The model was instrumented with rows of conventional pressure taps ...
