CPC classification number: F02C7/06 , F02K3/06 , F05D2220/32 , F05D2260/606 , F16N7/40 , F16N39/02 , F16N2210/02 , F16N2230/02 , F16N2270/56
Abstract: A gas turbine engine including a lubricant system defining a lubricant circuit through which a lubricant flows in fluid communication with a bearing assembly of the engine. The lubricant system selectively bypasses thermal communication of the lubricant and a heat sink based at least on a temperature of the lubricant within the lubricant circuit.

Abstract: Systems and techniques that facilitate predictive core rub diagnostics are provided. A sensor component can collect real-time operation parameters of a gas turbine engine. An analysis component can statistically combine first values, second values, and third values to yield a rub indicator for the engine. The first values can be based on a first comparison of fundamental mode placements of the engine, derived from the real-time operation parameters, and baseline fundamental mode placements. The second values can be based on a second comparison of a vibration spectrum of the engine, derived from the real-time operation parameters, and a baseline vibration spectrum. The third values can be based on a third comparison of the real-time operation parameters of the engine and baseline operation parameters. A classification component can generate a rub classification report indicating presence of rubbing in the engine, based on the rub indicator.

Abstract: Predictive models for diagnosing the unbalance state in an aircraft engine such as a jet engine based on engine vibrations and other known and/or determinable parameters are disclosed. Also disclosed are methods for developing the predictive model and using the model to identify aircraft engine unbalance.
