本文综述了跨音速非线性气动弹性的研究现状。讨论首先描述可能发生的一般非线性气动弹性行为，然后总结从飞行经验中吸取的教训。在气动流体流动和结构中识别非线性行为的物理来源。本文总结了有效计算非定常气动力的方法，最后讨论了跨音速流中颤振边界的理论和实验的相关性，以及几种不同气动弹性构型的各种物理源引起的极限环振荡（LCO）。

A review of the state of the art of transonic nonlinear aeroelasticity is presented. The discussion begins with a description of the generic nonlinear aeroelastic behavior that may occur followed by a summary of lessons learned from flight experience. Physical sources of nonlinear behavior are identified in both the aerodynamic fluid flow and the structure. Methods for the efficient computation of unsteady aerodynamic forces are summarized and then the chapter concludes with a discussion of correlation of theory and experiment for flutter boundaries in transonic flow and limit cycle oscillations (LCOs) arising from a variety of physical sources for several distinct aeroelastic configurations.
