After wind-tunnel tests showed that the flutter weight penalty of a long-span, low-drag truss-braced wing (TBW) is small enough to make the configuration feasible for future energy-saving airliners, NASA and Boeing are planning additional tests to assess the design’s aerodynamic performance. Aeroelastic analysis of the TBW design was conducted under Phase 2 of Boeing Research & Technologies’ (BR&T) NASA-funded Subsonic Ultra Green Aircraft Research (Sugar) program to ...
