针对传统国内外热流算法以及某些国外商业软件只计算单行星轨道航天器外热流的不足,提出了太阳系行星际轨道航天器的外热流计算方案。本文方案采用积分定义法,平行光线法,近似法,插值法,考虑行星椭圆轨道的影响以及面元遮挡。仿真计算结果表明,该方案符合行星际轨道外热流物理特性,其计算效率和精度较高。
Aiming at the shortcomings of the traditional domestic and international heat flow algorithms and some foreign commercial softwares only calculating the heat flux outside the single-orbit orbiter, the calculation scheme of the external heat flux of the solar system interplanetary orbit spacecraft is proposed. In this paper, the method of integral definition, parallel ray method, approximation method, interpolation method, taking into account the impact of the planet elliptical orbit and face occlusion. The simulation results show that this scheme accords with the physical characteristics of extra-orbit heat flow, and the calculation efficiency and accuracy are high.
