| 摘要: |
| 以基于平流层底部的准零风层风场进行区域驻留的新型临近空间浮空器为研究对象，介绍了其工作原理和系统组成。通过建立动力学模型、高度调控模型和能源模型，分析浮空器在基于飞行速度约束和基于南北范围约束两种工作模式下的区域驻留能力，并讨论浮空器在这两种工作模式下的动态能源特性。对长沙地区风场环境的研究结果表明，相对于无控自由飞行状态，浮空器在两种工作模式下均可实现100 km直径范围的长时驻留，基于飞行速度约束工作模式对能量的消耗更低。 |

| Abstract: |
| A novel near-space aerostat based on quasi zero wind-layer field for station-keeping was investigated. The working principle and system composition of the aerostat were introduced first. After that, a model comprising of dynamics, altitude control and energy circle was established. The properties of station-keeping and energy circle of the aerostat were studied in two typical working modes: flight speed limitation and north-south displacement limitation. With the weather input of Changsha, it is found that, compared with uncontrolled free-flying mode, the aerostat can achieve long resident in a 100 km diameter range under both working modes. Moreover, the energy consumption of the aerostat with flight speed limitation mode is lower than that of the other mode. |
