N2 - ISHM capability enables a system to detect anomalies, determine causes and effects, and predict future anomalies. It provides advice to improve operations based on health status, and includes user interfaces for integrated awareness of the health of the system. NASA Stennis Space Center (SSC), NASA Ames Research Center (ARC), and Pratt & Whitney Rocketdyne (PWR) are currently implementing a core ISHM capability that encompasses the A1 Test Stand and the J-2X Engine. The implementation incorporates all aspects of ISHM; from anomaly detection (e.g. leaks) to root-cause-analysis based on failure modes and effects analysis (FMEA), to a user interface for an integrated visualization of the health of the system (Test Stand and Engine). The implementation provides a low functional capability level (FCL) in that it is populated with few algorithms and approaches for anomaly detection, and root-cause trees from a limited FMEA effort. However, it is a demonstration of a credible ISHM capability, and it is inherently designed for continuous and systematic augmentation of the capability. The paper describes all aspects of the current implementation, and on-going activity leading to a pilot capability that could potentially support the J-2X test program.
