Addressing UHARW’s gust loads, this study uses EDH-connected FFWT for GLA via CFD-multi-body loose coupling. Key parameters (flare angle, inertia, stiffness, damping) and gust wavelengths analyzed. Prelim results: max 14.92% lift (30° flare) & 25.77% wing root bending reduction (120.0c gust) vs fixed tips. FFWT adapts, cutting local loads.
