TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
Impact Technologies proposes to develop a real-time prognostic and fault/failure accommodation system of critical electric power system components including power converters and electro-mechanical drives for the aerospace and aeronautical industry. The innovation of project is focused on the integration of emerging prognostic technologies with fault tolerant methodologies to improve system reliability and mission readiness for NASA's next generation electrical power systems. The proposed concept will utilize incipient fault detection techniques to provide longer predicted horizons prior to failures, and time to trigger the appropriate reconfiguration scheme. Impact Technologies' approach uses fault detection circuits and algorithms to analyze data from several sources including electrical and environmental measurements, model estimates, and usage conditions. Up-to-date assessments of the electrical system health and remaining useful life of critical components will be made possible via an on-board embedded processing system, which continuously updates prognostic models with sensed data and predicts the best fault accommodation strategy to meet mission objectives. The proposed electrical system fault prognosis and accommodation approach will be demonstrated with a Motor/Generator/Drive test bench adapted for use in this program and with data from the modern aerospace power system and electromechanical actuators.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Reliability assessment and diagnostic methods for power electronics device and actuator will increase safety and controllability for Crew Exploration Vehicles, Reusable Launch Vehicles, Unmanned Air Vehicles, and future generation of general aviation platforms. It will lead to benefits in the form of improved reliability, maintainability, and survivability of safety-critical aerospace systems.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
The potential commercial use of the developed technologies is broad. Examples of key customers that could benefit through use of the developed technologies include: unmanned combat air vehicles, JSF, future combat systems, commercial airlines, land and marine propulsion systems, industrial actuation systems, and robotic applications. The aero propulsion domain alone has thousands of potential systems to address with this technology.

NASA's technology taxonomy has been developed by the SBIR-STTR program to disseminate awareness of proposed and awarded R/R&D in the agency. It is a listing of over 100 technologies, sorted into broad categories, of interest to NASA.
