Abstract Details

2021, Master of Science in Engineering, Youngstown State University, Department of Mechanical, Industrial and Manufacturing Engineering.
The TJT-3000 on the campus of Youngstown State University is like one of many micro turbine engines used in UAV and other large RC aircraft. This project aims to analyze and propose improvements to the combustion chamber of micro turbine engines using the TJT-3000 as a baseline. These improvements would include an overall increase in the combustion chamber without heavily increasing the overall temperature reaching the turbine inlet. To analyze these criteria, the feasibility of using a handheld Creaform scanner for the purpose of scanning small turbine engine components is tested. The scanner was found to be viable, but a finer resolution was desirable as the scanned data from these scanned components would be refined and turned in to CFD capable models. The created CFD models in this project required a considerable amount of post processing to prepare. With a baseline model to compare to experimental data of the turbine engine, hypothesized geometric changes were applied to the turbine engine where the impact of each change would be considered and summarized. Based on the CFD models and literature review it was found that the geometric changes of the combustion chamber should be focused on improving the flow rate through the engine without extinguishing the produced flame while as much of the initial relatively cold flow coming from the compressor should be directed towards the back of the combustion chamber to cool the turbine inlet. Restricting the amount of flow through the combustion chamber leads to a higher pressure drop and an increase in combustion efficiency at the cost of unmanageable chamber wall temperatures, while geometry modifications that force flow through the inner most sections of the combustion chamber first will increase the cooling of the turbine stator inlet with a manageable increase in combustion chamber wall temperatures.
