| Abstract: | A method for determining the unusual noise sources generated by a chinesebuilt turboshaft engine is presented in this paper. The unusual noise sources are determined by the use of multiple-point noise measurement and spectrum analysis on a chinesebuilt engine and a prototype one at the test station. Analytical results show that the unusual noise source is chiefly due to unsteady combustion. |
