摘　　要：针对地球大气再入返回器的辐射加热计算方法开展了研究,采用NASA的高温空气辐射加热预测软件QRAD中用到的四光谱带模型,同时考虑了辐射散热效应及非平衡辐射加热。对于返回舱大底的辐射加热分布特性,采用了基于牛顿压力分布的计算方法。计算结果表明,发展的高超声速再入体辐射加热预测方法结果可靠。A radiative heating calculation method for reentry vehicles into the earth＇s atmosphere was studied, the four band spectra model in the QRAD for high temperature air was used. The heat dissipation due to radiation and the non-equilibrium effect were considered. The Newton pressure distribution was used for the radiative heating distribution calculation of reentry vehicles bottom faces. The results indicate that the method developed in the paper can predict the radiative heating of reentry vehicles into the earth＇s atmos- phere.
