Novel Coatings for Full Field Strain Measurements

提高飞机安全性的一种方法是开发新的技术，允许飞机结构与操作员“交谈”，并在他们需要注意的时候发出指示，就像人类神经系统一样。这就需要新的和新颖的检查方法，能够放大缺陷，从而消除传统的检查技术，或者至少引导检查人员到当地进行进一步的调查。这个PHD的目的是开发一种完整的机身涂层或“油漆”，不仅可以指示位置，还可以量化损害。这一涂层的开发将导致一种新的全场方法，用于快速的“热点”位置检测和随后的主应变测量，从而产生更详细的信息，以量化飞机结构健康监测中的缺陷。新的涂层将用于优化、预测性和基于条件的维护操作，管理和发展机身的健康监测。该项目可能包括在空客和NPL的安置，并将涉及与空客承包商VisEng Ltd的密切合作。研究将是多学科的，涉及一些材料开发和测试、喷雾物理和应变测量。

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.
