TECHNICAL ABSTRACT ( Limit 2000 characters, approximately 200 words)
Impact Technologies, with support from the Georgia Institute of Technology and Honeywell, propose to develop and demonstrate a suite of real-time Fault Contingency Management (FCM) algorithms for application within an Integrated Vehicle Health Management (IVHM) system. The proposed FCM software will implement a novel vehicle subsystem fault accommodation approach based on a seamless integration between real-time system health identification and adaptive controller techniques. Specifically, the continuous health assessment algorithms include a real-time adaptive recursive system identification algorithm and an enhanced real-time moving horizon estimation (MHE) algorithm that will be developed and implemented on a prototype embedded system.

The proposed FCM software hierarchy will act from the subsystems level up through the vehicle level and will implement fault-accommodating control, health management, and contingency management to accomplish its goal. The significant technology advancement proposed herein is based on the use of dynamic simulation models in a real-time computing environment to not only update health status predictions, but also to determine "on the fly" how accommodate for them. At the conclusion of Phase I, the project team will deliver a proof-of-concept demonstration of the proposed techniques running on an embedded platform using high fidelity propulsion and aircraft simulation models.

POTENTIAL NASA COMMERCIAL APPLICATIONS ( Limit 1500 characters, approximately 150 words)
The real-time Fault Contingency Management technologies will be directly applicable to Propulsion IVHM, Crew Exploration Vehicle, Reusable Launch Vehicles, Unmanned Air Vehicles and future generation 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.
