METHOD FOR PROMOTING THE DETECTION OF DAMAGE TO THE TURBOCHARGED ENGINE PIPING DAMAGE Russian patent published in 2018 - IPC F01D17/08 F01D17/20 

FIELD: measuring equipment.

SUBSTANCE: subject of the invention is a method for providing a pipeline damage detection, wherein said pipeline is configured to deliver a compressed air stream, at the output of the high-pressure compressor of the gas turbine engine, to the first pressure sensor and the second pressure sensor of the computing device. Method comprises the following steps: measuring the first air pressure at the level of the first pressure sensor; measuring the second air pressure at the level of the second pressure sensor; determining the theoretical pressure of the air flow at the output of the high-pressure compressor; performing a first check of the difference between the first value and the theoretical pressure; performing a second check of the difference between the second value and the theoretical pressure; carry out a final check, which is positive if the first check of the difference and the second check of the difference were positive, and negative otherwise. Also a computing device is presented comprising a set of instructions that allow a method to be implemented to ensure the detection of pipeline damage.

EFFECT: invention facilitates the detection of pipeline damage in a turbojet engine.
