【摘要】 平流层飞艇太阳能电池的温度对电池转化效率有着显著的影响;同时在正午时分可能对飞艇蒙皮以及内部浮升气体的温度造成不利的影响,并恶化飞艇的"超热"、"超压"现象。因此,很有必要对平流层飞艇太阳能电池热性能进行分析;但是相关研究却不是很全面。建立了平流层飞艇太阳能电池热性能分析数值模型,包括太阳能电池的太阳辐射模型、多层热传递模型。基于该数值模型,开发了MATLAB仿真程序。设计并开展了飞艇太阳能电池温度地面测试试验,对所建的热模型进行了验证。在研究过程中,分析了太阳能电池在一天内的温度变化情况。此外,详细讨论了日期、隔热层、太阳能电池外部封装层透波率以及风速等因素对于太阳能电池温度的影响。可以为平流层飞艇太阳能电池的设计提供有用的参考信息,为平流层飞艇热控制及热设计提供依据。更多还原

【Abstract】 Temperature of solar array on stratospheric airship has a significant effect on the solar cell efficiency and it may exert an adverse influence on the temperature of the airship envelop and internal floating gas at noon,more over it will make the "over hot"and "over pressure"phenomenon of airship even more worse. Hence,it is necessary to analyze the thermal performance of solar array on stratospheric airship but the related research is not very comprehensive. A numerical model is developed for analyzing the thermal performance of solar array on stratospheric airship,including the solar radiation model of solar array and the multi-layer heat transfer model. On the basis of the numerical model,a MATLAB simulation program is developed. The temperature test of solar array is designed and developed on the ground,and the thermal model is validated. In the process of the study,the temperature of solar array in one day is analyzed. In addition,the influences of the date,the thermal insulation layer,transmissivity of external encapsulation layer of solar array and wind speed on the solar array temperature are discussed in detail. The obtained result can provide useful reference information for the design of solar array on stratospheric airship,and provide the basis for thermal control and thermal design of stratospheric airship.更多还原
