TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
Fault to Failure Progression (FFP) signature modeling and processing is a new method for applying condition-based signal data to detect degradation, to identify fault modes, and to produce system estimates for State of Health (SoH) and Remaining Useful Life (RUL). The base technology has been applied for prognostic purposes for various government-sponsored programs, but FFP signature modeling and processing has not been applied for the area of Fault Management, nor does it include such features as fault dictionaries, lookup tables, and management algorithms. The technology includes Ridgetop-designed and developed algorithms to do the following: (1) perform Kalman Filtering to reduce noise; (2) transform sensor signal data to reveal underlying (hidden) FFP signatures; (3) normalize units-of-measure dependent signal data into dimensionless FFP signatures to facilitate re-use and reduce the time to characterize and define new FFP signatures; (4) define and use model definitions that reduce memory requirements and support fast and accurate processing and calculations; (5) two forms of trajectory curve characterization, both straight-line and curvilinear; (6) a fast yet accurate, graphics-based mathematical routine to adapt an FFP model to received data; (7) amplitude and time updates similar to Extended Kalman Filtering to estimate how long it will take an adapted FFP model to reach a defined failure threshold; and (8) produce SoH and RUL estimates that rapidly converge to the estimated time-to-failure (TTF) solution. The FFP signature modeling and processing will include additional innovation to support FM to minimize application-specific programming, those include algorithms to simplify fault identification and isolation.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
The proposed FM design and development tool suite is potentially a highly valued solution in fault management (FM) for detecting, identifying, isolating, and mitigating faults, especially degradation fault modes that lead to failure. The technology developed under this program will provide substantial benefits for fault mitigation of complex systems having autonomic recovery requirements. NASA has a need for new and innovative fault management (FM) approaches, architectures, and tools to improve the FM design, development, verification & validation, and operation processes. For this reason NASA is investigating methodologies with the main objectives of increasing reliability of FM systems and reducing costs. This technology could be implemented in several of NASA's Marshall Space Flight Center (MSFC) programs as well as those from, for example, Ames Research Center (ARC) and Jet Propulsion Laboratory (JPL). Key applications include space vehicles for space missions, commercial and military aircraft.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Main customers for the FFP signature modeling and processing will be firms such as The Boeing Company, UTC Aerospace, and Northrop Grumman, among others that will be willing to employ FM. Ridgetop received a letter of support from Northrop Grumman expressing interest in this technology and will provide subject-matter expertise and consulting services during the phase 1 of this SBIR. If phase 2 is awarded, Northrop Grumman is interested in validating and evaluating this technology in their laboratories and implementing it into some of their programs.
