Distribution of Aero-Engine Turbine Blades Life Based on Few Data[J]. Aeronautical Manufacturing Technology, 2010, 53(8): 71-78. DOI: 10.16080/j.issn1671-833x.2010.08.008.
Distribution of Aero-Engine Turbine Blades Life Based on Few Data
3D mathematical model is built considering the factors affect blade life
such as failure mode and maintenance condition. HPT-1 blades life distribution histogram is obtained by dimensional reduction. The error is assumed between the histogram and the Weibull distribution curve assumed with least square method
which provides an available method for field data management and a proof for HPT-1 maintenance arrangement of aviation enterprise. It is of importance for reducing downtime
and improving operation efficiency for aviation enterprise.
