摘要
平流层飞艇能源系统的可靠性对于飞艇设计是至关重要的。对能源系统的可靠性进行了分析和研究。首先,对太阳电池阵、可再生燃料电池,以及能源系统拓扑进行了可靠性分析;进一步结合推进系统配置可靠性分析的结果,对能源系统与推进系统的基本组合可靠性进行了研究;最后,提出了可靠性改进的组合拓扑方案。结果显示,采用可靠性改进组合,能源与推进系统的可靠性提高了17.5%。
The reliability design of the power system plays an important role in the design of a stratospheric airship. In this paper, the reliability of the power system of a stratospheric airship was discussed. At first, the reliability of the solar array, fuel cells and the topology of the power system were separately analyzed. Then, according to the result of the reliability analysis of the configurations of the propulsion system, the combined reliability of the power system and propulsion system was discussed. It is shown that the reliability of the power and propulsion system increased 17.5 % by using the combined improving approach.
