Increasingly accurate life prediction models are required to utilize the full capability of current and future advanced materials in gas turbine engines. Of particular recent interest are predictions of the lifetimes of engine airfoil materials that

Historically, cyclic life limited gas turbine engine components have been retired when they reached an analytically determined life where the first fatigue crack per 1,000 parts could be expected. By definition, 99.9% of these components are being re

Historically, gas turbine engine disks are retired when they accrue an analytically determined lifetime where the first fatigue crack per 1000 disks could be expected. By definition then, 99.9 percent of these components are being retired prematurely

This paper presents the results of a study using Pratt & Whitney’s probabilistic-based life analysis system to define the impact of damage tolerance requirements now being written into design specifications. An advanced turbine disk design was cons

The evaluation of the RFC/NDE System has produced capability characteristics in the format of â vs. a or apparent cracksize vs. actual cracksize. Although crack sizing has long been a major concern of NDE practitioners and theoreticians, the analysi

This paper presents results of Monte Carlo simulation of the Retirement-for-Cause (RFC) engine maintenance system as developed by Pratt and Whitney Aircraft and the U. S. Air Force. The Retirement-for-Cause concept is addressed, conventional Monte Ca

An empirical description of fatigue crack propagation (FCP) under complex loadings, typical of those experienced by gas turbine disks, is presented. This approach uses a three coefficient sigmoidal curve (SINH) to model the macroscopic effects on FCP
