I began my journey at CAE as a Research Assistant, working as part of a four-member team on a PKR 13.6 million project aimed at addressing the challenge of detecting defective (specifically loose and internally cracked) rivets in engine intake area and aircraft structure. My role primarily focused on the mechanical and computational aspects, from investigating rivet failure mechanisms through computational analysis to the development of a scanning system capable of operating within the operational constraints of aircraft structure. After evaluating several possible approaches, we selected Lock-In Thermography (LIT) as the most suitable inspection technique for the application. However, in order to effectively apply LIT to this problem, we required a method to extract meaningful information from raw thermal data. We developed an indigenous post-processing scheme combining Discrete Fourier Transform (DFT) and Wavelet Transform techniques to address this issue. After developing a scanning methodology and post-processing technique, the system was validated through scanning on multiple platforms, such as K-8, T-37, F-7PG, and JF-17. Building on this, I designed a mechanical platform for the remotely operated robotic scanning system, allowing access to confined regions within the aircraft engine area where inspection was not possible previously. This significantly improved the practicality and efficiency of the scanning process. The technology was ultimately matured to Technology Readiness Level (TRL) 6, following which the system was handed over to the field for data collection and evaluation.
