초록
Micro wave rotor is expected to improve the performance of micro gas turbines drastically. In the present study, a micro wave rotor test rig was designed and built for micro gas turbines of 1-10 kW output range, and its test runs were carried out with cold air flow. In the previous experiments, the leakage loss had large influence on its operating condition. Therefore, abradable coating was applied on the end walls to achieve the operation with zero clearance for leakage reduction and its improvement on the operating condition is discussed in this study.
