摘　　要：以伞衣负荷比值为标准选择了两类伞型,在典型的有限和无限质量条件下进行了风洞和空投试验开伞过程的研究。探讨了开伞过程中伞衣形状变化与伞衣承受开伞动载之间的关系及其影响因素,比较并分析了两种状态下不同试验手段得出的试验结果的差别,总结了各自的特点,并得出了关于两种降落伞性能试验的结论。Through the experiments on typical parachute opening process,and by using the canopy load ratio as a standard to choose the two classes of parachute,the wind tunnel and airdrop tests for its opening process were conducted in typical ＂limited＂ and ＂unlimited＂ quality conditions.The relationships between the canopy shape and dynamic load in opening process and their corresponding influencing factors were detailedly discussed and studied.Differences between two test results were also compared and further analyzed.And their characteristics were indicated.In addition,some conclusions of several parachute performances were drawn in the end of this paper.
