中文摘要：

降落伞载荷研究是降落伞研究的一项重要内容,首次将降落伞的弹性现象和伞衣载荷结合在一起考虑。首先理论探讨了降落伞工作过程时伞衣动载的产生原理及其影响因素。在此基础上,采用了不同弹性的伞衣材料及不同弹性的连接绳连接方式,对平面圆形伞在定常风洞情况下的开伞过程进行了试验研究。获得了伞衣载荷和伞形之间的动态关系,发现降落伞弹性现象对伞衣载荷有重要的影响。试验结果表明降落伞弹性增强,会加大降落伞工作过程的不稳定性,呼吸现象更为明显;伞衣载荷的波动峰值增加,振动频率加快,同时会使充气推迟,充气时间延长。该实验研究可为降落伞的载荷分析提供一定的依据。

英文摘要：

The parachute payload analysis is one of important contents in the parachute investigation.The parachute elastic behavior and canopy payload was considered together for the first time in this paper.The mechanism of production and influence factor for the canopy payload was discussed during the parachute working process in theory at first.Basis on this,the canopy and connecting rope of the differential elastic material were adopted.The opening process of the flat-circle parachute was experimental investigate...
