Abstract
Because of the high rotating speed, big air flow rate and high exhaust temperature of the areoengine, strong noise occurs in the engine test process. In this paper, the power spectrum analysis method of the areoengine test noise was discussed, and the noise measurement and analysis experiments of a turboprop engine test were carried out. The noise level, main noise resource and noise characteristics of this turboprop engine were analyzed and the noise control performance of the aeroengine test bench was evaluated. The experimental results indicated that the noise analysis method was feasible, whose analysis results were consistent with the theory, and could be used to diagnose the areoengine fault by the engine test noise analysis. Meanwhile the experimental results could provide the reference to the noise reduction design of the areoengine test bench.
