Abstract
Overspeed events may occur in the operation of aero-engines,which may lead to hazardous engine consequences of"uncontained high-energy debris".Based on the safety requirements of aero-engine airworthiness certification for overspeed events,this paper analyzes the requirements of electronic overspeed protection system for a new type of sensors.We analyze the measured signals of the exploratory test of exhaust electrostatic monitoring of a certain type of aero-turboshaft engine.The analysis results show that the spectrum information of the electrostatic sensor signal can dynamically track the rotor speed in real time.The power turbine speed between 170-180 Hz and its doubling frequency are identified in the spectrum information under six output shaft power conditions of 75,210,420,630,840 and 1 000 kW.The obtained results demonstrate that electrostatic sensor has potential applications in aero-engine overspeed monitoring.关键词
