摘　　要：随着飞机跨海飞行业务愈趋频繁,提高飞机水上迫降性能显得越来越重要。本文通过国外CN-235-300M型飞机与WG30直升机撞水试验两个案例分析了飞机水上迫降动力模型试验研究进展,同时,对国内外数值模拟技术研究现状与进展进行了详细介绍。分析比较模型试验与数值模拟方法各自的优势,考虑到飞机水上迫降问题具有流固耦合特性,涉及结构变形、水的可压缩性以及非线性自由表面等问题,因此,利用SPH方法、有限元法以及混合分析等方法解决飞机水上迫降问题将是未来的主要研究方向。With the increasing frequency of cross-sea flights, it is more and more important to improve the performance of aircraft landing on water. This paper analyzes the research progress of the dynamic model test of airplane ditching on water through the two cases of the water impact tests of a CN-235-300 M airplane and a WG30 helicopter conducted abroad. At the same time, the research status and progress of the numerical simulation technology at home and abroad are introduced in detail. The respective advantages of model test and numerical simulation methods are analyzed and compared. In light of the fluid-solid coupling characteristics of the aircraft water landing problem, which involves structural deformation, water compressibility and non-linear free surface, applying SPH method, finite element method and hybrid analysis methods to solve the aircraft water landing problem will be the main research direction in the future.
