Methods for determining goals and expectations for fielded jet engines

摘要

This thesis investigates methods for determining goals and expectations for fielded jet engines. Some of these methods employ concepts used in Reliability Centered Maintenance (RCM). The procedures developed here can be applied to any fielded jet engine. The data used by this thesis was extracted from the Naval Aviation Logistics Data Analysis (NALDA) database. The desktop software programs that were used to attain reliability parameters are readily available to any command. The data analysis accomplished here demonstrated that cannibalization of engines has impacted adversely on reliability. A model was developed to determine no-build times for jet engines at the Intermediate Maintenance and Depot level of repair based on engine reliability and the conditional probabilities of survival of significant components of the engine and their specified maximum operating times.
