Prognostics for Aerospace Propulsion Systems
This document applies to prognostics of aerospace propulsion systems. Its purpose is to define the meaning of prognostics in this context, explain their potential and limitations, and to provide guidelines for potential approaches for use in existing condition monitoring environments. It also includes some examples.
1.2 Field of Application
This document seeks to meet the increasing interest in prognostics for aerospace propulsion systems. Specifically, the document tries to provide a timely guideline for applying prognostic technologies to enhance the capability of current monitoring and diagnostic systems. Some examples are provided that are intended to illustrate different approaches and methodologies.
Rationale: This Aerospace Information Report (AIR) was developed to provide insights and examples of how prognostic algorithms can be used in support of monitoring and maintaining aerospace propulsion systems, with an initial focus on gas turbine engines and their subsystems. This revision includes updates reflecting the aerospace industry’s latest thoughts on when prognostic algorithms are useful and how they can be classified. It also includes expanded examples to reflect common methods which have been used in the field.
