  • Patent number: 10221735
    Abstract: A method of real-time oil consumption is disclosed. A method of real-time oil consumption detection may include capturing a raw oil quantity, calculating a corrected oil quantity, calculating a predicted oil quantity, calculating a prediction error, and calculating an estimated oil consumption rate. Raw oil quantity may be captured from an oil quantity sensor in an engine. Corrected oil quantity may be calculated by taking raw oil quantity and applying environmental and engine operational conditions. Prediction error may be calculated by finding the difference between corrected oil quantity and predicted oil quantity. Oil consumption rate may be calculated by applying a regression algorithm to prediction error.

  • Publication number: 20050034924
    Abstract: An emergency lubrication system for a turbine engine includes a reservoir 50 containing a reserve quantity of lubricant 52 and having a lubricant inlet 54 and a lubricant outlet 56. A lubricant supply line 62 and a lubricant outlet line 66 each have a respective valves 64, 68 for regulating lubricant flow into and out of the reservoir. A fluid supply line 70 includes a valve 72 for selectively establishing communication between the reserve quantity of lubricant and a source of pressurized fluid. During normal operation the lubricant outlet valve continuously releases lubricant at a normal rate to the component requiring lubrication while the lubricant inlet valve concurrently admits fresh lubricant into the reservoir. During abnormal operation, the lubricant inlet valve closes in response to abnormally low lubricant pressure outside the reservoir thereby preventing backflow of reserve lubricant out of the reservoir.
