Rolls-Royce are synonymous with safe and reliable power, and produce the world's most efficient aerospace gas turbine engine. To maintain safety and efficiency, Rolls-Royce perform routine inspection and servicing of their engines throughout its lifecycle. As engines wear, the most critical components may show signs of deterioration that may lead the engine to be removed from service ahead of its next scheduled overhaul. To address these challenges, and to maximise engine availability and time on-wing, Rolls-Royce continues to lead the way in the development of in situ inspection and repair techniques. Such tools can be deployed via a range of access holes (or "borescope ports") across the side of the engine, and navigated to the area of interest. Once there, a range of inspection and maintenance tasks can be performed by a highly-skilled mechanic, such that the engine can be safely returned into service. Due to the geometrical restrictions, and the required dexterity and capability of the tools, this approach is analogous to keyhole surgery.THEMIS (THickness Evaluation and Measurement In Situ) aims to increase Rolls-Royce's portfolio of in situ inspection techniques. In particular, the aim is to develop a process that can measure the thickness of components and coatings when the engine is still intact and installed. This will allow an even more in-depth understanding of the integrity of the asset, and thus allow the mechanic to determine whether further maintenance is required or if the engine is safe to fly-on. THEMIS is highly challenging project, but would help to develop a technique that would have a significant value to the Rolls-Royce Aftermarket Services team.

劳斯莱斯是安全可靠动力的代名词，并生产世界上最高效的航空航天燃气涡轮机发动机。为了保持安全和效率，劳斯莱斯在其整个生命周期内对其发动机进行例行检查和维修。随着发动机的磨损，最关键的部件可能会出现退化的迹象，这可能导致发动机在下一次计划检修之前停止使用。为了应对这些挑战，并最大限度地提高发动机的可用性和在翼时间，罗尔斯·罗伊斯继续引领现场检查和维修技术的发展。这种工具可以通过发动机侧面的一系列进入孔（或“管道镜端口”）部署，并导航到感兴趣的区域。一旦到达那里，一系列的检查和维护任务可以由一个高技能的机械师执行，这样发动机就可以安全地恢复使用。由于几何形状的限制，以及所需工具的灵活性和能力，这种方法类似于锁孔手术。THEMIS（厚度评估和测量原位）旨在增加劳斯莱斯的原位检测技术组合。特别是，目标是开发一种可以在发动机仍然完好无损并安装时测量部件和涂层厚度的工艺。这将有助于更深入地了解资产的完整性，从而使机械师能够确定是否需要进一步维护或发动机是否可以安全飞行。THEMIS是一个极具挑战性的项目，但将有助于开发一种对劳斯莱斯售后服务团队具有重要价值的技术。
