Prediction of transient responses of a folding wing during the morphing process

Authors: Yonghui Zhao, Haiyan Hu

Abstract:
Accurate prediction of the structural dynamic characteristics of a folding wing during the morphing process is a prerequisite for performing transient aeroelastic analysis. In view of this fact, this paper develops a set of differential-algebraic equations that govern the time evolution of the folding wing during the morphing process by using the floating frame approach. Using the established equations of motion, the transient responses of the wing during the morphing process are computed. The developed equations can be further integrated with the CFD codes to carry out the transient aeroelastic analysis of the morphing wing.
