One way to enhance the safety of aircraft is through the development of new techniques that allow the structure to "talk" to the operators and indicate when they require attention, in a similar way to the human nervous system. This necessitates new and novel inspection methodologies that have the ability to magnify defects and thus, either eliminate traditional inspection techniques, or at least guide the inspectors to local areas for further investigation. The aim of this PhD is to develop a whole airframe coating or "paint" that can not only indicate location but also quantify damage. This coating development would lead to a new full-field methodology for rapid 'Hot Spot' location detection and subsequent measurement of the principal strains, resulting in more detailed information to quantify defects in the structural health monitoring of aircraft. The new coating will be implemented in optimized, predictive and condition-based maintenance operations, managing and developing health monitoring of the airframe. The project may include placements at Airbus and NPL and will involve working closely with an Airbus Contractor, VisEng Ltd. The research will be multidisciplinary, involving some materials development and testing, the physics of spraying, and strain measurement.

提高飞机安全性的一种方法是开发新技术，让飞机结构与操作员“对话”，并在他们需要注意时发出指示，就像人类的神经系统一样。这就需要新的和新颖的检查方法，这些方法具有放大缺陷的能力，因此，要么消除传统的检查技术，要么至少引导检查人员到局部区域进行进一步的调查。本博士的目的是开发一种整个机身涂层或“油漆”，不仅可以指示位置，还可以量化损伤。这种涂层的发展将导致一种新的全领域方法，用于快速“热点”位置检测和随后的主应变测量，从而获得更详细的信息，以量化飞机结构健康监测中的缺陷。新的涂层将用于优化、预测和基于状态的维护操作，管理和开发机体的健康监测。该项目可能包括在空中客车和国家物理实验室实习，并将与空中客车承包商VisEng Ltd密切合作。这项研究将是多学科的，涉及一些材料的开发和测试，喷涂物理和应变测量。
