Risk Assessment Methodologies for Fracture-Critical Components
Abstract
Within gas-turbine aeroengines, fracture-critical components are defined as those whose in-service failure would hazard the entire aircraft. For these components, airworthiness regulations require that a maximum permitted service life be identified, such that the probability of failure occurring before this life is reached is extremely remote. However, although the intent behind the derivation of these lives is to minimize the possibility of in-service failure, the procedures used to establish them are not usually specified in terms of this probability of dysfunction itself.
