Fabrication of Bladeless Propulsion Jet Engine
2025
Overview
This study presents the design, fabrication and evaluation of a novel bladeless propulsion system inspired by the Dyson Air Multiplier principle, to advance sustainable and efficient air mobility. The proposed system eliminates conventional rotating blades by employing fluidic dynamics to generate thrust, thereby offering the potential for reduced noise, enhanced safety and improved environmental compatibility. A systematic methodology encompassing conceptual design, feasibility analysis, material selection and prototype fabrication was adopted, with 3D printing enabling precision manufacturing and rapid customisation. Experimental investigations were conducted to measure thrust performance, airflow characteristics and acoustic emissions, with the results benchmarked against theoretical predictions. The findings reveal a strong correlation between experimental and analytical outcomes, validating the feasibility of bladeless propulsion for aerospace applications. While minor discrepancies highlight areas for further refinement, the overall performance demonstrates significant promise for integration into Unmanned Aerial Vehicles (UAVs) and future aerospace platforms. This work underscores the transformative potential of bladeless propulsion technology, laying a foundation for quieter, cleaner and more efficient aviation solutions.
