摘要

摘要: 针对平流层气球的热动力学仿真问题，提出一个可以计算升空轨迹、速度变化以及气球蒙皮温度分布的综合模型.主要分析了气球基本热力学行为和受力状况，建立气球动力学和运动学方程，以计算升空过程的轨迹和速度变化.通过将气球蒙皮分割成若干面元，研究了蒙皮面元瞬态能量平衡方程，以计算气球蒙皮温度分布.在热力学、动力学和运动学分析的基础上，建立气球综合热动力学仿真模型.引入实测风场数据，计算在实际风场条件下，平流层气球升空和驻留阶段任意时刻的热力学特性.

Abstract: In respect for the thermal-dynamic simulation of stratospheric balloon, a comprehensive model that can calculate the ascending trajectoryand, the velocity variation as well as the film temperature distribution was proposed. Basic thermal characteristic and loaded forces of the balloon were analyzed.The dynamic and themotion equations were established to calculate the trajectory and velocity of the balloon. By dividing the balloon film into surface elements, the transient thermal equations of the film element was described to calculate the film temperature distribution.Measured wind data was introduced to simulate the thermal-dynamic performance at any moment during ascending and floating in real wind circumstances.
