英国未来飞行愿景和路线图定义了到2030年英国航空业的发展前景。作为未来飞行演示部分的一部分，项目HADO（高强度自主无人机操作）将在伦敦希思罗机场开发、测试和部署全自动无人机系统（UAS）操作。然而，现实世界的测试，资源需求的性质表明，开发和提高基于虚拟环境的测试方法的可靠性和效率是必不可少的这种操作的发展。尽管如此，开发一个高保真和实时的虚拟环境，使安全，可扩展和可持续的开发，验证和验证的UAS操作仍然是一项艰巨的任务。值得注意的是，以高度相关性集成物理和虚拟元素的需求提出了重大挑战。因此，作为HADO项目内的合成测试环境工作包的一部分，本文提出了一个数字孪生（DT）系统，使混合现实测试的自主无人机操作的背景下。它将物理世界与由五个不同的层和几个数字元素组成的数字世界连接起来，以支持增强的混合现实功能。本文重点介绍了如何建立的合成测试环境的静态层，并提出了一个DT原型，支持混合现实测试功能。特别是，演示了将虚拟障碍物注入物理测试环境的能力，突出了虚拟环境和现实之间的清晰界限如何模糊，以安全，灵活，高效和有效地测试UAS操作。
The UK Future Flight Vision and Roadmap defines how aviation in the UK is envisioned to develop by 2030. As part of the Future Flight demonstration segment, project HADO (High-intensity Autonomous Drone Operations) will develop, test, and deploy fully automated Unmanned Aircraft System (UAS) operations at London Heathrow airport. The resource-demanding nature of real-world tests, however, suggests that developing and improving the reliability and efficiency of virtual environment-based testing methods is indispensable for the evolution of such operations. Nonetheless, developing a high-fidelity and real-time virtual environment that enables the safe, scalable, and sustainable development, verification, and validation of UAS operations remains a daunting task. Notably, the need to integrate physical and virtual elements with a high degree of correlation presents a significant challenge. Consequently, as part of the synthetic test environment work package within the HADO project, this paper proposes a Digital Twin (DT) system to enable mixed-reality tests in the context of autonomous UAS operations. This connects a physical world to its digital counterpart made up of five distinct layers and several digital elements to support enhanced mixed-reality functionality. The paper highlights how the static layers of the synthetic test environment are built, and presents a DT prototype that supports mixed-reality test capabilities. In particular, the ability to inject virtual obstacles into physical test environments is demonstrated, highlighting how the sharp boundaries between virtual environments and reality can be blurred for safe, flexible, efficient, and effective testing of UAS operations.
