| Abstract: |
| Introduced the software design and monitor for performance parameters,lubrication oil parameters and vibration parameters of turbo shaft engine to know engine health in time.It gave that which parameters were used to diagnose single assembly faults of engine.The method to diagnose single assembly faults by means of fault factor was discussed.Faults data and without fault engine simulation shows that the system has creditable conclusions and practical values for monitoring turbo shaft engine on active duty. |
