Title:
ENGINE DIAGNOSIS DEVICE
Document Type and Number:
Japanese Patent JP2019143480
Kind Code:
A
Abstract:
To improve a prediction accuracy at a turbine outlet temperature of a jet engine of an aircraft.SOLUTION: An engine diagnosis device 10 comprises an engine operation data holding part 11 where engine operation data including data of a turbine outlet temperature; a prediction formula holding part 12 where air temperature and air pressure formula are accumulated; air temperature and air pressure formula holding part 13 where air temperature and air pressure data are accumulated; an air temperature acquisition converter part 14 for calculating prediction expression of air temperature data to calculate the prediction data of air temperature; an air pressure acquisition converter part 15 for calculating the prediction formula of the air pressure data to calculate the prediction data of the air pressure; an engine operation data retrieval part 16 for extracting engine operation data approximate to the air temperature and the air pressure prediction data from the engine operation data of the engine operation data holding part; and an engine operation diagnosis part 17 for diagnosing whether or not the operation of the engine is normal in reference to a distribution of the turbine outlet temperature of the extracted engine operation data.SELECTED DRAWING: Figure 1
