    摘要:

    为了研究直升机典型构件的着水机理,并为仿真建模和验证提供实测数据,开展了不同构型的直升机典型元组件垂直入水试验研究,阐述了试验设计方法和过程,并对试验结果进行了分析。结果表明,结构弹性影响明显,同时空气缓冲作用也不可忽略,不同速度下两者对压力峰值影响存在明显差异。

    Abstract:

    In order to investigate the water entry mechanism of typical components of helicopter and provide measured data to simulation modeling and verification, we carry out a series of research on vertical water entry tests of the helicopter typical components with different construction. Test design method and its process are presented, and test results are analyzed. It is shown that the structural elastic effect is obvious and the effect of air cushion cannot be neglected. There is a significant difference between the two effects on the peak pressure at different speeds.
