摘　　要：近20年来长航时飞行的需求强烈,大柔性飞行器的几何非线性气动弹性问题逐渐凸显,使得气动弹性力学面临新的挑战。本文针对大展弦比大变形的柔性飞行器,调研和分析了目前几何非线性气动弹性工程研究领域中主要使用的气动建模方法,着重介绍基于片条理论、面元法和计算流体力学(Computational Fluid Dynamics,CFD)技术等气动建模方法在静、动气动弹性分析中的主要特点、研究现状与应用状况,并对大展弦比大变形机翼的气动弹性分析中气动力方法的发展提出若干建议,供气动弹性基础研究和工程应用研究人员参考。In recent twenty years, with the development of very flexible aircraft such as High Altitude-I.ong Endurance aircraft, geometric nonlinear aeroelasticity has become a research hotspot. The geometric nonlinear aeroelastic problems of very flexible aircraft are gradually highlighted, resulting in new challenges for aeroelasticity. This paper presents the aerodynamic modelling methods mainly used in geometric nonlinear aeroelastic analysis and engineering application, targeting flexible aircraft with high aspect ratio wings. The characteristics, research status and the application of strip theory, panel methods and Computational Fluid Dynamics （CFD） methods applied in static and dynamic aeroelastic analysis are introduced. By analyzing and summarizing the research development and status at home and abroad for geometric nonlinear aeroelasticity, this paper also proposes some conclusions and suggestions on aerodynamic modelling of high aspect ratio wing under large deformation as a reference to researchers in both aeroelastic theoretical and engineering fields.
