在降落伞的研究，华盖通货膨胀过程建模是最复杂的任务之一。当华盖经常在一很短的时间期间经历最大的变丑和装载，它具有为理论分析和试验性的大小的大困难。在这篇论文，空气动力学的方程和结构的动力学方程为描述降落伞洞过程，并且解决策略合并的反复的联合被开发上述方程为一个小规模、灵活、扁平通报的降落伞被建议。然后，分析在打开过程作为一个序列在光线的飞机为华盖几何学，里面之间并且在华盖外面的时间依赖者压力差别，在华盖附近的短暂旋涡和流动领域被执行。华盖形状开发的机制在通货膨胀进程期间从短暂流动领域的观点被解释。降落伞洞过程的实验在一条风隧道，华盖的即时形状被高速度照相机在测量被进行，装载的洞被测力计平衡测量。理论预言在对试验性的结果的好同意被发现，验证建议途径。这个数字方法能改进关于风隧道测试的降落伞研究的强壮的依赖的状况，并且具有到降落伞通货膨胀过程的力学的理解的意义。

英文摘要：

In the research of parachute, canopy inflation process modeling is one of the most complicated tasks. As canopy often experiences the largest deformations and loa-dings during a very short time, it is of great difficulty for theoretical analysis and experimental measurements. In this paper, aerodynamic equations and structural dynamics equations were developed for describing parachute opening process, and an iterative coupling solving strategy incorpo- rating the above equations was proposed for a small-scale, flexible and flat-circular parachute. Then, analyses were carried out for canopy geometry, time-dependent pressure difference between the inside and outside of the canopy, transient vortex around the canopy and the flow field in the radial plane as a sequence in opening process. The mechanism of the canopy shape development was explained from perspective of transient flow fields during the inflation process. Experiments of the parachute opening process were conducted in a wind tunnel, in which instantaneous shape of the canopy was measured by high velocity camera and the opening loading was measured by dynamometer balance. The theoretical predictions were found in good agreement with the experimental results, validating the proposed approach. This numerical method can improve the situation of strong dependence of parachute research on wind tunnel tests, and is of significance to the understanding of the mechanics of parachute inflation process.
