However, as time progressed, the gas turbines proved to be a greater challenge, becoming increasingly difficult to construct. Evolve and advance. Improving a minor aspect of the gas turbine necessitates a thorough examination of the gas turbine's multiple functional areas, necessitating the acquisition of new knowledge and skills. Although the detail may be minute, its impact on overall performance would be significant. Until recently, these miniature jet engines played no vital role in the aviation industry and were mainly utilized for model jets. In spite of the fact that, according to the history of scientific development, these engines are being investigated and prepared for integration into Unmanned Aerial Vehicles (UAVs) as their propulsion system. This document covers the development of a miniature turbojet engine based on the model of king-tech K310G. the authors of this document took inspiration from king-techs design and made modifications to it. The focus of this project is mainly on the compression ratio produced. Design and dimensioning of the Miniature turbojet engine is the most crucial step in this endeavor, then comes the manufacturing process which describes how the parts were made. from there the authors study the flaws that they encountered while making the project and the techniques they used to solve them. Lastly two major sections have been discussed in detail which are practical phase and the assembly of all the parts together with the electronic components and lastly the final testing of the Miniature turbojet engine’s compression testenThesis
