Many current challenges in Non-Destructive Evaluation (NDE) stem from the increased use of advanced materials and manufacturing processes that push the limits of materials' performance. NDE techniques are required that can cope with extreme environments (high temperature / radioactive environments), restricted access (inside engines or though access ports), and complex geometries. To address these challenges, this project will develop a new capability for real-time, remote ultrasonic imaging that can be used for NDE. This engineering challenge will be achieved by introducing a conceptual change to phased array ultrasonics, beyond the limits of geometrical, ultrasonic frequency and mode array characteristics, by adapting the array to the demands of the inspected structure, on-the-fly, and thus transforming the field. The long-term vision behind this project goes beyond inspection, to develop a method for monitoring and control of in-process parameters, in places of extreme environments such as fusion reactors or turbine engines. The industrial importance of the project is demonstrated by the significant cash and in-kind contributions of the project partners.

当前无损评估 (NDE) 中的许多挑战源于先进材料和制造工艺的使用增加，从而突破了材料性能的极限。 NDE 技术需要能够应对极端环境（高温/放射性环境）、受限进入（发动机内部或通过进入端口）和复杂的几何形状。为了应对这些挑战，该项目将开发一种可用于无损检测的实时远程超声成像新功能。这一工程挑战将通过对相控阵超声波引入概念上的改变来实现，超越几何、超声波频率和模式阵列特性的限制，通过使阵列适应被检查结构的需求，即时进行转换，从而实现转变。领域。该项目背后的长期愿景不仅仅是检查，而是开发一种在聚变反应堆或涡轮发动机等极端环境中监测和控制过程参数的方法。项目合作伙伴提供的大量现金和实物捐助证明了该项目的工业重要性。
