为改进传统外热流算法未考虑外热流经多次反射后的吸收和国外商业软件未考虑轨道摄动及太阳矢量变化对外热流的影响等不足,重新定义了外热流角系数和外热流辐射传递因子,综合SGP4轨道模型和Gebhart方法,给出了考虑摄动等因素的辐射传递因子和轨道外热流计算模型,以及相应的计算流程。通过仿真分析论证了考虑多次反射及摄动等因素的重要性。
In order to improve the traditional external heat flow algorithm without considering the absorption of external heat flux after multiple reflections and the influence of external commercial software on the external heat flow without considering the orbital perturbation and the change of solar vector, the external heat flow angle coefficient and the external heat flux radiation transfer factor Based on the SGP4 orbital model and the Gebhart method, the radiative transfer factor and the orbital heat flux calculation model considering the perturbation and other factors are given, and the corresponding calculation flow is given. The importance of considering multiple reflection and perturbation factors is demonstrated through simulation analysis.
