摘要
将平底直升机底部形状简化为一矩形平板,基于经典的水动力冲击理论,建立简化的刚体运动方程,对其求解得到着水载荷及压力分布的估算方法。计算结果与国外相关资料比较,其准确性可以满足实际工程的要求。
The helicopter bottom shape was simplified as a rectangular plate. Based on the classical hydrodynamic impact theory, the simplified rigid motion equations were established, and the estima- tion of impcat loads and pressure distribution were developed. The results were compared with for- eign references, and the accuracy could satisfy the requirements of engineering.
