【摘要】 地效飞行器是一种利用地面效应原理飞行的运载工具。通常,地效飞行器机身对称断阶着水时的水动力载荷对机身的作用力最大。所以,准确地掌握船体的着水载荷,对于减轻机身结构的重量有着重要作用。本文采用数值计算方法,得到了某型号地效飞行器对称断阶着水过程中重心处过载系数,以及机身底部蒙皮上的压力分布规律。该结果与地效飞行器设计规范得到的结果相符合,并且计算方法和结果可用于指导具体的地效飞行器型号结构设计。更多还原

【Abstract】 Wing in ground effect crafts(WIG crafts) is a type of vehicles flying on the wing in ground effect.Usually,the slamming force on the body of WIG Craft is most severe when the body step approaching water symmetrically.So,to know exactly the water load can help relieving the structure weight of the body.The numerical method was used to compute the overload factor at the center of gravity of a WIG craft,as well as the pressure distribution on the bottom skin of the body.The results agree well with the results of the design regulations.The method and the results can be applied to guide the structure design of a WIG craft.更多还原
