WebNov 3, 2024 · 2. Considering aeroelastic flutter, when an eigenfrequency of the wing meets with an aerodynamic frequency, the commonly mentioned solutions make sense: avoid the convergence zone by limiting speed, or by increasing the wing's eigenfrequency trough stiffness, reduced weight, or reduced span. Makes sense, especially if I use the spring … WebNov 12, 2024 · Nov 12, 2024 at 14:51. Yes indeed, the wings flap up and down more if the engine is positioned closer to the wing tip. But flutter is not the flapping, it is the twisting backwards of the wingtip. The wing bends upwards in flight, the closer to the tip the engine is mounted the higher the wing bending relief.
