Abstract

The temperature shock of solar panels causes a whole spectrum of disturbances. The most significant of them are indignation in the first seconds after a temperature impact. However, long-term thermal effects also induce disturbances. One such phenomenon is thermal deformation. Some studies indicate that thermal deformations in certain solar panel systems (for example, ROSA) can compromise the controllability of small spacecraft. However, modern literature lacks quantitative assessments of this impact. This work aims to quantify microaccelerations in spacecraft angular motion induced by thermal deformations of solar array panels. Such an assessment will establish management protocols to enhance the efficiency of executing target tasks for small spacecraft. Specifically, this involves gravitationally sensitive processes and high-precision remote Earth sensing from space.

太阳帆板阵列热冲击下航天器内部环境微加速度动力学仿真

太阳能电池板的温度冲击会引起一系列的干扰。其中最重要的是在温度冲击后的最初几秒钟内的愤慨。然而，长期的热效应也会引起扰动。其中一种现象是热变形。一些研究表明，某些太阳能电池板系统（例如ROSA）的热变形会损害小型航天器的可控性。然而，现代文献缺乏对这种影响的定量评估。本研究旨在量化太阳帆板热变形引起的航天器角运动微加速度。这种评估将建立管理协议，以提高小型航天器执行目标任务的效率。具体来说，这涉及到引力敏感过程和从太空进行的高精度远程地球遥感。

期刊介绍： Microgravity Science and Technology – An International Journal for Microgravity and Space Exploration Related Research is a is a peer-reviewed scientific journal concerned with all topics, experimental as well as theoretical, related to research carried out under conditions of altered gravity. Microgravity Science and Technology publishes papers dealing with studies performed on and prepared for platforms that provide real microgravity conditions (such as drop towers, parabolic flights, sounding rockets, reentry capsules and orbiting platforms), and on ground-based facilities aiming to simulate microgravity conditions on earth (such as levitrons, clinostats, random positioning machines, bed rest facilities, and micro-scale or neutral buoyancy facilities) or providing artificial gravity conditions (such as centrifuges). Data from preparatory tests, hardware and instrumentation developments, lessons learnt as well as theoretical gravity-related considerations are welcome. Included science disciplines with gravity-related topics are: − materials science − fluid mechanics − process engineering − physics − chemistry − heat and mass transfer − gravitational biology − radiation biology − exobiology and astrobiology − human physiology
