First Claim
Patent Images
1. A method of detecting debris within a lubricant stream, the method comprising:
- generating data indicative of debris and sensor system functionality within a lubricant stream with a sensor system;
communicating the data to a controller;
calculating features from the data that are indicative of a debris within the lubricant stream;
compiling the calculated features over time during operation; and
classifying the compiled features.

Abstract
A method of detecting debris within a lubricant stream, the method includes generating data indicative of debris and sensor system functionality within a lubricant stream with a sensor system. The data is communicated to a controller. Features calculated from the data are indicative of a debris within the lubricant stream. The calculated features are compiled over time during operation. The compiled features are classified. An oil debris monitoring system for a turbine engine is also disclosed.

10. An oil debris monitoring system for a turbine engine, the oil debris monitoring system comprising:
-
a sensor assembly mounted proximate to a lubricant conduit for generating a signal indicative of particles within a lubricant stream flowing through the lubricant conduit; a feature generator configured to receive the signal from the sensor assembly and generate a data stream including features representing characteristics of the lubricant stream; a feature accumulator configured to compile the features during an operational period of the turbine engine and storing the compiled features in a memory device; and a fault isolator configured to classify the compiled features after the operational period is concluded and generate an output identifying anomalies in the features. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
