摘要
水面环境对水陆两栖飞机着水载荷有重要影响,水面环境分为静水和波浪,采用数值仿真技术对静水面和波浪水面环境下的水陆两栖飞机着水载荷进行计算。利用单机身模型,通过与实验对比,验证仿真方法的有效性及精度;基于推板造波理论实现数值造波,结合静水面着水仿真技术实现波浪水面着水仿真。研究发现,静水面着水仿真精度较高,应用数值造波方法模拟的波浪品质可以满足工程应用。
The water surface environment has an important impact on the water load of the amphibious aircraft.The water environment is divided into still water and waves.The numerical simulation technique is used to calculate the water load of the amphibious aircraft under the calm water and the wave environment.Using the single-body model,the effectiveness and accuracy of the simulation method are verified by experimental comparison.The numerical wave-making is realized based on the wave-making theory of the push-plate,combined with calm water simulation technology to realize wave landing simulation.It can be showed that the simulation accuracy of the calm water landing is high,and the wave quality simulated by the numerical wave method can meet the engineering application.
