Patent attributes
Using tachometer-from-vibration processing of component signals and appropriate configuration allows for the analysis of both the compressor turbine and the power turbine of a turboshaft, turboprop, or twin spindle turbofan engine. One smart vibration sensor is positioned on or near the turbo engine and detects vibration data for components of both the gas compressor turbine and power turbine without the need for direct measurements of tachometer data from both the compressor and power turbine. From this, condition indicators are determined for monitored components on the sensor and returned to an onboard control unit.
