Abstract

We computed the ablation of different spherical artificial meteoroids entering from a low-Earth orbit in the context of the AllBert EinStein mission. AllBert EinStein is intended to reenter spheres of known size and material into the atmosphere to determine the percentage of kinetic energy converted to light. This paper models the reentry to predict magnitude curves for the different initial conditions. An emphasis is placed on determining the difference between the single body ablation model and ESA’s reentry software SCARAB. It is also shown how the CFD simulations can work in synergy with SCARAB results to increase detail in the airflow regime around. Our study shows that with few fixes the meteor method replicates with good accuracy the SCARAB results for different artificial meteoroids, showing the validity of both tools.

用ESA的SCARAB软件模拟流星体消融

在AllBert EinStein任务的背景下，我们计算了从低地球轨道进入的不同球形人造流星体的烧蚀。阿尔伯特·爱因斯坦计划将已知大小和材料的球体重新进入大气层，以确定动能转化为光的百分比。本文建立了再入过程模型，以预测不同初始条件下的震级曲线。重点放在确定单个烧蚀模型和欧空局的再入软件SCARAB之间的差异。它还显示了CFD模拟如何与SCARAB结果协同工作，以增加周围气流状态的细节。我们的研究表明，流星方法在很少的固定值下可以很好地复制SCARAB对不同人工流星体的结果，显示了这两种工具的有效性。
