| 摘 要： | 在考核过载承受能力的火箭橇试验后,橇体内发现有水,从空气动力学的角度,对火箭橇体进水现象进行了初步分析,并利用FLUENT软件对进水原因进行了初步研究,通过分析,发现结构在穿越跨音速阶段时,由于内外压差的变化将导致内部或外部产生水汽。该发现为结构设计提供有益的建议。

| Abstract: | After the rocket sleigh test which tests if the structure can bear the overload of rocket,some water was found inside the sleigh,From aerodynamic angle,the author make elementary research on the rocket sleigh's water penetration,and also compute the water penetration phenomenon by FLUENT software,through analysis,water steam can be generated inside or outside the structure when it cross transonic stage.The analysis can provide some useful suggestion for the structure designing. |
