摘要
降落伞系统具有非常复杂的动力学特性,为了较精确的计算降落伞气动力,深入研究其流场特性,采用计算流体动力学方法,对某试验用降落伞充满稳定阶段流场进行数值模拟,计算结果与试验数据吻合较好,表明该数值模型可靠,具有较高精度。
The dynamic behavior of parachute system is an extremely complex phenomenon. By applying the Computational Fluid Dynamics （CFD）, the flow field of the parachute fully developed is computed based on the three dimension Navier-Stodes equations closed with S-A turbulence model. The simulation results are agreement with the experiment dates, which verifies that the accuracy of the numerical simulation model is ensured. The methods used in this paper can also be used in the design of other parachute systems.
