摘要
简单介绍了平流层气球的特点和研究现状,引出并描述了轨迹控制系统,它几乎无需消耗能源,使长耗时平流层平台成为可能。提出了平流层气球轨迹控制飞行系统的仿真模型,并分别从风速轮廓线、大气密度以及气球、绳和集成翼方面逐一详细分析并进行建模,最后分析了整个飞行系统的特点和求解系统平衡点的难点所在,提出了一种可行的平衡点估算方法。结果表明,该平衡点估算方法可以快速有效地求得整个飞行系统的平衡点。
Serving as an important platform, stratospheric balloon is introduced briefly with its characteristics and the present situation. The trajectory control system studied is depicted, and then the simulation model is proposed from an overall view. Afterwards, wind profile, the density of air as well as balloon, tether and the assembly wing are analyzed and modeled in detail respectively. Finally, with an analysis of the characteristics of the entire flight system and the difficulties in solving the equilibrium point, a feasible method of equilibrium point estimation is brought forward.
