WebThese results compare well with the results found by Palacios and Epureanu in "An Intrinsic Description of the Nonlinear Aeroelasticity of Very Flexible Wings". Their analysis, which was also based on lifting line aerodynamics predicted a flutter speed of 141 m/s and a flutter frequency of 69.8 rad/s. This page was generated using Literate.jl.

WebAeroelasticity is the branch of physics and engineering studying the interactions between the inertial, elastic, and aerodynamic forces occurring while an elastic body is exposed to a fluid flow. The study of aeroelasticity may be broadly classified into two fields: static aeroelasticity dealing with the static or steady state response of an elastic body to a … 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 …
