On the Aeroelasticity of the Active Span and Passive Pitching Polymorphing Wing: Effect of Morphing Rate

This paper studies the effect of morphing rate on aeroelasticity a polymorphing wing capable active span extension and passive twist/pitch. A variable domain size finite element model is developed to capture dynamic effects due presence in Euler–Bernoulli beam model, which introduces structural damping term equations motion. The various rates aeroelastic boundaries system, namely, flutter velocity frequency, examined for undergoing retraction, from baseline 25% vice versa, respectively. Three points interest are analyzed: at start morphing, mid-point just before process ends. parametric analysis carried out determine varying critical parameters, such as elastic axis location outboard section adjoining spring torsional rigidity wing.
