METHOD OF GAS TURBINE ENGINE VIBRATION MONITORING |
摘要 |
FIELD: engines and pumps.SUBSTANCE: reference vibration characteristic is obtained via basic vibration characteristic produced in measurement and registration of vibration signal values at rotor working rpm at ground engine tests and includes generation of working vibration characteristic. For this, preset series of flights are carried out whereat vibration signal value at rotor working rpm local operating vibration characteristic is formed to set the threshold of deviation of local working vibration characteristics from basic one. Every obtained local working vibration characteristic is compared to basic one while said local working vibration characteristics not falling beyond preset threshold are used to form the reference vibration characteristic.EFFECT: higher accuracy and validity of engine diagnostics in flight and at test ground.1 dwg |
