Failure Analysis of Engineering Structures: Methodology and Case Histories
Case 44: Failure of an LP Turbine Disc in an Aircraft Engine
-
Published:2005
Abstract
During cyclic spin tests, the turbine disc in an aircraft engine broke apart with a loud noise, followed by a fire. Based on a detailed examination and the results of SEM fractography and hardness measurements, failure analysts concluded that a locking plate became dislodged due to the shearing of the screws that hold it in place. They also provided recommendations to remediate the problem.
