THE DESIGN OF AIRCRAFT ENGINE COMPRESSOR: LEARNING KIT FOR SEMESTER 4 IN POLITEKNIK BANTING

Abstract

Understanding the operational theory of aircraft engine compressors, especially axial compressors, is a challenge for aircraft maintenance students due to the lack of effective visual tools that demonstrate airflow dynamics and component interactions. This study aims to design a high-fidelity aircraft engine compressor learning kit. A survey was conducted among aircraft maintenance student’s semester 4 to identify critical learning challenges, and the findings were analysed using a Pareto diagram to prioritize design features based on student needs. To generate and evaluate multiple design alternatives, a morphological matrix was used for concept development, while the final design selection was made using a Pugh matrix, ensuring optimal balance of functionality, cost, and educational effectiveness. The implementation of the learning kit resulted in a 30% to 42% increase in student comprehension of compressor airflow dynamics, pressure stages recognition, rotor/ stator stage functionality, overall concept understanding, and hand-on confidence, based on pre- and post-intervention assessments over 50 students from Semester 4. Over 80% of students reported better engagement and understanding with the kit compared to traditional methods. This project successfully bridges the gap between theoretical and practical learning, enhancing students' understanding and preparing them for real-world aerospace maintenance tasks.
