摘要
气动升力对水陆两栖飞机着水载荷会产生较大的影响,采用理论分析研究不同气动升力对着水载荷的影响,确定了载荷增量、加速度增量与气动升力减小量之间的关系。利用典型水陆两栖飞机剖面模型,运用耦合欧拉-拉格朗日方法对水陆两栖飞机着水进行仿真计算,得到气动升力变化量与载荷变化量之间的关系,表明了水陆两栖飞机着水加速度增量大约是气动力减小量的0.33倍。
The aerodynamic lift has great influence on the water loading of amphibious aircraft.The influence of different wing lift on water load was studied theoretically,and the relationship between load increment,acceleration increment and wing lift reduction was determined.Using a typical amphibious plane profile model,using the coupled Eulerian Lagrangian method to amphibious plane water simulation calculation,get the aerodynamic lift variation and the relationship between the load variation.The results show that,the increment of the hydrostatic acceleration of amphibious aircraft is about0.33times that of aerodynamic reduction.
