Nonlinear aeroelastic phenomena are very difficult to predict and potentially disastrous. Numerical continuation techniques could be used to predict such phenomena, but they cannot currently treat complex systems with many degrees of freedom. The goal of this project is to develop nonlinear model reduction techniques that will enable the application of continuation techniques to large-scale aero-elastic problems. An important contribution of this work will be to develop reduction methods that adapt the reduced model based on the evolution of the dynamics and that also account for parameter variations.

非线性气动弹性现象是很难预测和潜在的灾难。数值延拓技术可以用来预测这样的现象，但他们目前不能处理复杂的系统与许多自由度。本项目的目标是开发非线性模型降阶技术，使延拓技术能够应用于大规模气动弹性问题。这项工作的一个重要贡献将是开发减少方法，适应减少模型的基础上的动态演变，也占参数变化。
