【摘要】 本研究提出了一种结合Simulink和FlightGear的联合仿真方法,针对可重复使用火箭的返回射场任务进行可视化分析。通过Simulink构建的飞行动力学模型,并利用FlightGear实现运动显示,本文详细描述了从CAD建模到协同仿真执行的全过程,强调了使用开源工具链的优势,包括AC3D建模和C代码实现Simulink与FlightGear间的通信。该方法不仅提高了对复杂航天器动态行为理解的效率,而且为制导、导航和控制研究领域提供了一种端到端的开源解决方案,具有广泛的应用潜力。更多还原

【Abstract】 This paper proposes an integrated simulation method using Simulink and FlightGear for the visualization analysis of the return to launch site(RTLS) missions for reusable launch vehicles(RLVs). By employing a flight dynamics model constructed in Simulink and utilizing FlightGear for motion display, this paper provides a detailed account of the entire process from CAD modeling to the execution of collaborative simulation.The approach highlights the advantages of using an open-source toolchain, including AC3D for modeling and C code for communication between Simulink and FlightGear. This method not only enhances the efficiency of understanding the complex dynamic behaviors of spacecraft but also offers an end-to-end open-source solution for the Guidance, Navigation, and Control(GNC) research field, with broad application potential.更多还原
