This research article explores Urban Air Mobility (UAM) from a System of Systems (SoS) perspective in order to understand the impact of different fully electric UAM aircraft architectures on the overall SoS capability. For this purpose, a framework, combining aircraft design methods with an agent-based simulation, is developed. Thereby, not only different UAM aircraft architectures, but also fleet combinations, technology scenarios, and operational strategies are studied and evaluated for different success criteria. The UAM fleets are simulated for 24-hour operations, considering non-uniform passenger demand, dispatch of passenger as well as deadhead flights, aircraft architectural performance, load factor, energy consumption, and turnaround procedures. A large design of experiments, consisting of approximately 5,000 design points, is executed. Eventually, this article demonstrates the proof of concept for the proposed SoS framework and provides several parameter sensitivities for a given UAM scenario. For such complex SoS, analytical methods would not suffice for understanding complex and often nonlinear interactions. Therefore, the proposed simulation driven framework proves to be successful by providing sensitivity study results, linking subsystem, system (aircraft) and system of system (fleet) level. Thus, the framework allows for comprehensive understanding of the SoS design space and is important for successful deployment or optimization of UAM aircraft & fleet for a given city and operational context.

使用系统方法系统的城市空中交通的飞机架构和机队评估框架

这篇研究文章从系统系统 (SoS) 的角度探讨了城市空中机动性 (UAM),以了解不同的全电动 UAM 飞机架构对整体 SoS 能力的影响。为此,开发了一个将飞机设计方法与基于代理的模拟相结合的框架。因此,不仅针对不同的成功标准,研究和评估了不同的 UAM 飞机架构,而且还研究和评估了机队组合、技术方案和运营策略。UAM 机队模拟 24 小时运行,考虑了非均匀的乘客需求、乘客调度以及空头航班、飞机结构性能、负载系数、能源消耗和周转程序。执行由大约 5,000 个设计点组成的大型实验设计。最后,本文展示了所提出的 SoS 框架的概念证明,并为给定的 UAM 场景提供了几个参数敏感性。对于如此复杂的 SoS,分析方法不足以理解复杂且通常是非线性的相互作用。因此,通过提供敏感性研究结果,链接子系统、系统(飞机)和系统(机队)级系统,所提出的仿真驱动框架被证明是成功的。因此,该框架允许全面了解 SoS 设计空间,对于在给定城市和运营环境下成功部署或优化 UAM 飞机和机队非常重要。分析方法不足以理解复杂且通常是非线性的相互作用。因此,通过提供敏感性研究结果,链接子系统、系统(飞机)和系统(机队)级系统,所提出的仿真驱动框架被证明是成功的。因此,该框架允许全面了解 SoS 设计空间,对于在给定城市和运营环境下成功部署或优化 UAM 飞机和机队非常重要。分析方法不足以理解复杂且通常是非线性的相互作用。因此,通过提供敏感性研究结果,链接子系统、系统(飞机)和系统(机队)级系统,所提出的仿真驱动框架被证明是成功的。因此,该框架允许全面了解 SoS 设计空间,对于在给定城市和运营环境下成功部署或优化 UAM 飞机和机队非常重要。
