文摘A fundamental design of using thermophotovoltaic(TPV)system to convert the huge aerodynamic heat into electricity during the reentry process was described.The influences of heat conducting way,spectral filter and selective radiating surface on the system performance were analyzed in detail.The results showed that as a thermal conducting component,SiC is better than ablation material,with more electricity output but a larger cooling load,and that the adoption of spectral filter and selective radiating surface could lower the power output to some extent,yet diminish the cooling load prominently.
