Abstract

The heat exchange between a spacecraft and its environment is an important factor determining the thermal regime of the spacecraft. In this work, we collected, sorted, and supplemented well-known algorithms for calculating the external thermal effect on a spacecraft in a near-planet orbit (of arbitrary planet of the Solar system). We present a technique of determination of external radiative heat fluxes on an arbitrarily oriented spacecraft surface, based on trajectory data. The influence of the spacecraft rotation about a longitudinal axis on the heat fluxes is considered. The results of numerical simulations are presented in the paper.

轨道太空飞行中的辐射热通量

摘要

航天器与其环境之间的热交换是决定航天器热状态的重要因素。在这项工作中，我们收集、整理和补充了众所周知的算法，用于计算在（太阳系的任意行星）近行星轨道上的航天器的外部热效应。我们提出了一种基于轨迹数据确定任意定向航天器表面上的外部辐射热通量的技术。考虑了航天器绕纵轴旋转对热通量的影响。本文介绍了数值模拟的结果。
