EngD research: Calibration and Control of Advanced Ultrasonic Phased Array Technology
My project was focused on the development of a methodology for calibrating ultrasonic phased array inspection systems for Full Matrix Capture (FMC) based data acquisition. I conducted the majority of my research on the investigation of the effect of variation in array element performance. This involved mathematical modelling as well as experiments and laboratory based trials. I was also able to apply the engineering skills I learnt during my undergraduate degree, on mechanical engineering, through the design of complex experimental equipment.
Whilst I was working on my EngD project Rolls-Royce Submarines had an existing project that aimed to develop a software platform for FMC based inspection. The calibration routine I developed was needed by this project and this required me to work closely with other NDE and software engineers to ensure my work was fit for purpose.
Overall I found my project both technically challenging and rewarding and it also gave me an opportunity to become involved in the wider project management of NDE Research and Technology (R&T) tasks within submarines, as well as providing valuable experience of presenting my work at national and international conferences.
NDE Research & Technology Technical Lead / Inspection Qualification Body (IQB) Chairman – Rolls-Royce Submarines
I currently work for Rolls-Royce Submarines in Derby and act as lead technical engineer for NDE R&T projects. I am responsible for the development of the NDE capabilities necessary for Rolls-Royce Submarines to meet the current and future requirements of the nuclear power plant used to power the Royal Navy’s fleet of submarines. I am also responsible for operating the Rolls-Royce IQB which independently reviews and approves inspections for safety critical areas of the nuclear power plant.
The two sides of my job allow me to keep up-to-date with the latest R&T developments focused on NDE, supervise current EngD projects, and review the inspections developed using the technology currently operated by our department in the factory as well as on-board submarines.
My EngD has provided me with in-depth technical skills that have enabled me to take an active role in the development of NDE technology within Rolls-Royce. These skills are invaluable as an NDE specialist and have also greatly helped my development as a professional engineer.
