在理论分析的基础上,建立了飞船外热流分析模型,解算出不同飞行姿态和模式下的外热流,分析得到外热流变化规律,得出极端外热流工况。分析结果表明:当姿态为三轴稳定时,外热流随受晒因子增大而增加;由三轴稳定转为偏航机动后外热流突然减小,且随受晒因子增大而减小。
Based on the theoretical analysis, the model of the external heat flow of the spacecraft is established, and the external heat fluxes are calculated and calculated according to different flight attitude and mode. The external heat flux variation is obtained and the extreme external heat flow conditions are obtained. The results show that when the attitude is three-axis stable, the external heat flux increases with the increase of the sunning factor, and the external heat flux decreases suddenly from the three-axis steady to the yawing, and decreases with the increase of the sunning factor.
