METHOD OF MONITORING ENGINE PERFORMANCE PARAMETER OF GAS TURBINE ENGINE

摘要

PROBLEM TO BE SOLVED: To provide a method for monitoring engine performance parameters of a gas turbine engine during operation.

SOLUTION: The method includes: a step of sensing the performance parameters and generating analog sensor outputs; a step of producing digital data by conditioning the analog sensor outputs with at least one hub unit 14 that is mounted sufficiently close to the engine to be subjected to a first temperature in excess of 125C; a step of receiving the digital data from the hub unit 14 with a collector unit 16 subjected to a second temperature of less than the first temperature; a step of receiving the digital data from the collector unit 16 with a distributor computer unit 18 subjected to a third temperature of less than the second temperature; and a step of processing the digital data with the distributor computer unit 18 to assess the engine performance parameters of the engine.
