摘要：
The scrapping rate of high pressure turbine (HPT) blades varying with cycles since new (CSN) was calculated in the dual failure modes, and the scrapping of HPT blades was observed after engine removal from wings.The relationship between scrapping rate and failure distribution of HPT blades was proposed in accordance with the theory of fatigue damage accumulation so that the failure distribution and life expectation of blades was obtained.Based on the proposal above and a large number of HPT blade maintenance data of a type of civil aero engine, the failure distribution function of HPT blades was fitted with CSN increasing.It was found that the failure of the Stage 1 HPT Blades of this type of aero engine was subject to exponential distribution, and the failure of Stage 2 HPT Blades subject to uncommon exponential⁃exponential distribution in the current reliability statistics. © 2022, Editorial Department of Journal of Aerospace Power.
