| 摘 要： | 为研究太阳帆板地面展开试验中气动阻力的影响,基于动网格技术提出了一种时变空气阻力计算方法。该方法采用CFD商业软件进行仿真计算,分析了三帆板地面低速展开的气动阻力影响。分析结果表明,该帆板在运动过程中所受的阻力较小,与工程设计的预估结果相近。

| Abstract: | To study the effect of aerodynamic drag in the solar array spreading on the ground,a calculation method of time-varying aerodynamic drag was put forward based on dynamic meshes in this paper.The commercial CFD software was used in simulation,by which the low spreading of a three solar array on the ground was computed.The result showed that the drag in spreading was rather small which was similar to the estimation in engineering design. |
