Aircraft Engine Compressor Learning Kit

Abstract

An educational kit simulating the working principle of an axial flow aircraft engine compressor has been developed to enhance student understanding through real-time visual and hands-on learning. The product was designed as a modular, interactive system featuring a transparent acrylic cylinder that allows airflow behaviour to be visualized using mist atomization. The core components, including rotors, stators, inlet, and exhaust structures, were modelled with 3D CAD software and fabricated using PETG filament to ensure durability and accuracy. The scope of the project included the complete cycle of design, 3D printing, mechanical assembly, electrical integration, and functional testing of the kit. A DC motor, shaft system, and adjustable speed regulator were implemented to simulate realistic airflow dynamics, while safety and ease of operation were prioritized through labelled controls and a stable PVC base. Upon completion, the product successfully demonstrated its ability to convert theoretical learning into observable aerodynamic behaviour, especially through the mist flow that reveals pressure and velocity changes along multiple compressor stages. The modular structure also enabled easy disassembly, allowing users to closely inspect individual components. Through classroom trials and practical demonstrations, the learning kit was shown to significantly improve student engagement and comprehension. In addition to its educational value, the project offered a low-cost, safe, and portable alternative to real engine exposure, making it ideal for use in technical institutions with limited resources. This project is expected to contribute to the advancement of engineering education by bridging the gap between textbook theory and real-world understanding in the field of aircraft propulsion systems.
