    FABRICATION AND TESTING OF SMALL SCALE METALLIC CENTRIFUGAL AIR COMPRESSOR
    (UMT, Lahore, 2024) Muhammad Sameer, Mohammad Bilal Hussain, Rafey Ahmad Khakwani and Mohammad Mohyuddin
    This project's primary objective is the fabrication and testing of small metallic centrifugal air compressor made out of metal alloy, built-in a micro jet engine using MW 54 Turbo Jet Engine as an inspiration which numerous researchers use as basis of development. Centrifugal impeller, an essential element, was made out of high strength Aluminum 2024 –T4 on a 5-axis milling machine; while the structure used 3D printed PLA, PET-G & ABS as part of this hybrid approach in compressor unit design to allow users to see its performance at different speeds. This thesis represents a final phase of work on a project designed to measure pressure & temperature variations between intake impeller components in a controlled environment. Utilizing sets of sensors and controllers to collect systematic data enabling the creation of comprehensive graphs, providing invaluable insights into performance trends. A DC single-shaft motor replacing traditional combustion chamber in this project. Redesigned intake impellers increased airflow within the chamber and are combined with an adjustable variable nozzle that enables unrestricted rotation of the turbine wheel. A small-scale generator measuring the useful power generated from free rotating turbine wheel. All sensors are positioned within the micro jet engine, which is securely mounted on a test stand. This test stand is equipped with four linear bearings to facilitate force measurements. This thesis includes a complete guide on designing, manufacturing, assembly, electronic wiring and testing of a micro jet engine centrifugal air compressor.
