Abstract

The measurement and analysis of aero-engine noise is of great significance to the fault diagnosis and analysis of aero-engine. The electret free field microphone is used to convert the engine noise into electrical signal. After conditioning and amplification, the virtual instrument based on PXI bus technology is used to collect the signal. Finally, the high-performance computer system is used to analyze and process the collected data, which provides data support for the test and fault diagnosis of the aero-engine. The noise test system of aero-engine can accurately collect, store and analyze the noise signal of engine running.
