Report Errors
In this study, a set of performance tests were carried out for 3D printed combustor components to investigate the performance of 3D printed component and its feasibility for the micro gas turbine engine. The test has been conducted for four different equivalence ratios under two different engine operating conditions, respectively. The measurement results show that the tested combustor has a low total pressure loss coefficient and a uniform exit temperature distribution. However, the combustion efficiency values are lower than 93.5%, which is considerably lower than the general gas turbine engine combustor. The performance data obtained from the tests will be used for combustor performance improvement using 3D printing technology.
