| 摘 要： | 文章综述了目前美国、俄罗斯和欧空局研制的火星降落伞中盘缝带伞的发展情况.在参考已有盘缝带伞结构设计的基础上,通过改变结构设计参数,设计出4种不同结构形式的盘缝带伞,并完成了高塔投放和低速风洞等初步性能试验.根据试验结果,对伞型的带宽比及透气量与阻力系数及稳定性之间的关系进行了讨论;最终得出带宽比、透气量大的盘缝带伞稳定...

| Abstract: | The paper summarized the development of mars parachute(disk-gap-band parachute) abroad now.Basing on structure design of desk-gap-band parachute abroad,four types of desk-gap-band parachutes have been designed by changing structure design parameter,and their elementary performance tests(tower drop test and low speed tunnel wind test) have been completed.Based on the test data,the relations among band width ratio,cloth permeability and drag coefficient,stability have been discussed,and the results are presented.The higher band width ratio and cloth permeability result in a better stability and a lower drag coefficient,whereas the lower band width ratio and cloth permeability result in a worse stability and a higher drag coefficient. |
