    Abstract
  • Based on the technological problem for lack of effective safety monitoring measures,the research for online detection of engine aerodynamic instability during aero-engine test was carried out.By analyzing engine instability characteristic data, the aerodynamic instability identification algorithm was designed based on time-frequency and wavelet analysis,and the online detection system of engine aerodynamic instability with one's own domestic intellectual property right was was developed.Result showed that the system can accurately and timely detect the engine aerodynamic instability characteristic signal, including excellent features such as,identification system response time was less 50 ms,and the project practicability was high.The research demonstrated the ability of online early warning to the engine test aerodynamic instability.
