| 摘 要： | 在降落伞轴向和径向动量方程的基础上进行一些合理的简化,并结合其他经验公式基本描述了降落伞整个充气阶段的运动过程。运用简化的模型初步分析了在不同大气密度、初始开伞速度下的充气环境对降落伞充气时间、充气距离,伞绳最大拉力的影响。得到的结论对火星降落伞设计及降落伞充气试验的环境模拟有一定参考意义。

| Abstract: | The parachute axis of symmetry equation and radial equation were rationally simplified.Integrated with other experienced formulas,the movement process of parachute inflation was described.The influence of atmosphere density and initial velocity on the parachute inflation times,inflation distance and max strain of suspension-line were analyzed by the simplified model.The result is importance to design of Mar parachute and simulate conditions of varied type parachute inflation experimentation. |
