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. This document also includes some examples. The current revision does not provide specific guidance on validation and verification, nor does it address implementation aspects such as computational capability or certification.
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. This revision also includes expanded examples to reflect common methods which have been used in the field.
