| 摘 要： | 文章对降落伞充气过程中的尾流再附现象进行了动力学分析。建立的尾流再附动力学模型包括:伞系统运动方程、尾流运动方程、伞衣-尾流动量交换方程。利用模型计算了3种不同开伞情况下尾流与伞衣的运动,得到尾流再附发生的条件。计算所得到的结论与试验结果一致。

| Abstract: | A model was presented for the dynamic analysis of the wake re-contact during the parachute inflation process. The model includes three parts: equations of the motion for the parachute-store system, equations of the motion for the wake, equations of the momentum transfer between parachute and wake. The model was used to analysis the wake re-contact during three different inflation processes. The result got from the model agrees with the result from the experiment. |
