Morphing　wing　aircraft　have　generated　increasing　interest　in　recent　years　owing　to　their　ability　to　alter　the　shape　and　configuration　of　the　wings　to　retain　optimum　flight　performance　under　different　flight　conditions.　However,　while　theoretical　approaches　have　greatly　advanced　our　understanding　of　the　nonlinear　vibrational　characteristics　of　morphing　wings　during　the　morphing　process,　little　effort　has　been　made　to　verify　the　results　of　theoretical　studies　based　on　corresponding　experimental　results.　The　present　work　addresses　this　issue　by　first　investigating　the　nonlinear　dynamic　behaviors　of　Z-shaped　morphing　wings　during　the　morphing　process　in　subsonic　flow　based　on　thin　airfoil　theory　under　ideal　incompressible　fluid　conditions.　First,　the　steady　aerodynamic　lift　on　the　morphing　wing　is　derived　and　the　nonlinear　partial　differential　equations　governing　the　morphing　wing　motion　are　established.　The　influence　of　the　folding　angle　on　the　nonlinear　responses　of　the　morphing　wing　is　investigated　via　numerical　simulations.　Then,　the　aeroelastic　characteristics　of　the　morphing　wing,　including　the　flutter　displacements　of　edge　points　on　the　outer　plate　of　the　wing,　are　investigated　using　the　computational　fluid　dynamics　module　in　ANSYS.　Finally,　the　results　of　theoretical　analysis　are　verified　by　experiments　conducted　with　a　corresponding　Z-shaped　morphing　wing　model.　(C)　2021　Elsevier　Masson　SAS.　All　rights　reserved.
