Non-Destructive Testing (NDT) Inspection Simulator

Abstract

This project deals with the design of a gamification-based NDT inspection simulator for aircraft maintenance students, focusing on ET training. ET is one of the common NDT techniques used for detecting both surface and near-surface defects in conductive materials. In general, practical training in this technique has been quite limited because of the availability of equipment, safety considerations, and operational costs. The project presents a digital simulator intended to be useful for students to learn and practice in an interactive, safe, and inexpensive virtual environment.The simulator developed on the Morph Matrix platform embeds a number of core gamification elements: scoring, guided tasks, interactive prompts, and instant feedback. In fact, these were some of the features to be embedded to enhance user engagement while attempting to reinforce correct inspection behaviour. The simulation is endowed with realistic 3D components, virtual manipulation of probes, and defect indication responses that emulate real ET behaviour. By interacting with these, users will be guided to learn the principles of electromagnetic induction and the importance of lift-off, probe orientation, and proper scanning techniques.The project applied several data-gathering methods in order to make sure the simulator fits actual training needs: questionnaire surveys, interviews with instructors, and documentation analysis of existing ET training procedures. The feedback received during development proved helpful in refining the user interface, inspection flow, and instructional clarity. The final system provides structured guidance for learners who may have limited exposure to real ET equipment, thus allowing them to practice repeatedly without time constraints or resource limitations.Feedback from using the simulator suggests that there is an improvement in the student's understanding of the basics of ET, defect detection methodologies, and signal response interpretation. Users were more confident in carrying out the inspection activities, such as probe handling, scanning sequence, and identification of defects. The virtual environment also reduces the risk associated with equipment misuse and eliminates the need for repeated use of costly ET test pieces.This project therefore highlights how gamification is integrated with simulation-based learning to enhance Eddy Current Testing knowledge retention, practical skills, and learner motivation. The NDT Inspection Simulator proves a useful addition to traditional training and reinforces the learning in the Diploma in Aircraft Maintenance Engineering program.
