| 摘要: |
| 高空气球为临近空间中的研究提供了可靠的低成本平台。目前高空气球球形一般直接采用“自然形”或以“自然形”为基础,但通用、简捷地求解“自然形”外形方程一直是个难点。将“自然形”气球外形求解问题转化为最优控制问题,利用最优控制领域成熟的求解工具——高斯伪谱法最优化软件包计算气球外形。此外,通过分析外形数据得到外形变化规律,设计通用算法求解任意球形控制因子、任意高度的“自然形”气球外形。结果显示,该算法无须调参便可计算所需的“自然形”球形,便于科研人员快速获得大量所需球形数据。 |

| Abstract: |
| High-altitude balloon provides a reliable low-cost platform for high altitude scientific experiments. The shape of the balloon is directly adopted as natural-shape or based on natural-shape； however, how to simply and quickly solve the natural-shape equation general-purpose is a difficult problem. The mature solution tool in the field of optimal control—gauss pseudospectral optimization software was used to solve the natural-shape balloon equation which is transformed into the optimal control description. Furthermore, a general algorithm was designed to solve the natural-shape balloon shape with any spherical control factor and any height by analyzing the shape data. Results show that this algorithm can calculate the required natural-shape without adjusting parameters, which is convenient for researchers to quickly obtain a large amount of required spherical data. |
