论文摘要
近年来，由于卫星在太空环境中的密度不断增加，几项研究集中在开发主动和被动策略以消除和减轻空间碎片的策略。这项工作调查了开发可靠，快速方法来分析卫星重新进入的可行性。数值模型将通过半分析方法获得的长期轨道传播与大气破坏性的重新进入阶段相连，从而利用了过冲边界的概念，这突出了太阳能电池板的早期破裂可以对重新进入的预测产生的早期中断的影响。选择ESA积分任务的重新进入作为测试案例，以证明该模型在产生重新输入的完整模拟中的效率。破坏性重新进入阶段的仿真是使用面向对象的方法产生的，并注意空间系统最关键的组件的可降期性过程。
In recent years, due to the constant increase of the density of satellites in the space environment, several studies have been focused on the development of active and passive strategies to remove and mitigate space debris. This work investigates the feasibility of developing a reliable and fast approach to analyze the re-entry of a satellite. The numerical model interfaces the long-term orbit propagation obtained through semi-analytical methods with the atmospheric destructive re-entry phase exploiting the concept of overshoot boundary, highlighting the effect that an early break-off of the solar panels can have on the re-entry prediction. The re-entry of ESA's INTEGRAL mission is chosen as a test case to demonstrate the efficiency of the model in producing a complete simulation of the re-entry. The simulation of the destructive re-entry phase is produced using an object-oriented approach, paying attention to the demisability process of the most critical components of the space system.
