Abstract
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.
