    摘要： A method for automatic monitoring of at least one component of a physical system, includes checking data of a data record for errors caused by a preceding data processing, checking the data in the physical context of the at least one sensor for errors resulting from infringements of assumptions of physical and/or system-related factors in elements of the measurement chain, the context of the component for errors resulting from infringements of the physical and/or system-related factors of the component, and—checking the individually asserted errors against one another and then either rejecting the error or outputting the error as an error message with reference to the error source.

    摘要： Methods and associated devices useful for the health monitoring of igniters of gas turbine engines are disclosed. Exemplary embodiments disclosed include the use of an accumulated spark count to an igniter to obtain an indication of wear on the igniter and/or the remaining life of the igniter. An exemplary method disclosed includes: receiving one or more signals indicative of a commanded spark count to the igniter for one or more ignition events; processing the one or more signals indicative of the commanded spark count to the igniter, determining a total accumulated commanded spark count to the igniter; and generating one or more signals indicative of at least one of an estimated wear on the igniter or an estimated remaining life of the igniter based on the total accumulated commanded spark count to the igniter.

    摘要： A method for assessing reliability in a gas turbine engine system includes using a processor to carry out instructions from a memory to propagate a physics-based model through a Bayesian network to assess reliability for the gas turbine engine system. A system for assessing reliability for a gas turbine engine system includes a memory including instructions to propagate a physics-based model through a Bayesian network to assess reliability for a gas turbine engine system. The system also includes a processor operatively connected to the memory to carry out the instructions. A network interface can be operatively connected to the processor to receive reliability data from operation of gas turbine engines, wherein the memory includes instructions for updating data module or modules based on reliability data.
