TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
To improve aviation safety with anticipated growth in capacity, it is necessary to develop flight control technologies that enable safe operations as anomalous conditions occur. These developments are particularly important to reduce fatal loss of control accidents due to aircraft degradation and abrupt aerodynamic changes including upsets. It is necessary to develop methods to identify and characterize anomalies in flight, as well as to estimate the impacts on the flight envelope and the ability to effect control forces for recovery and/or flight planning to achieve safe landing. An approach to identify anomalies including aerodynamic upsets based on model-based fault detection methods will be combined with physics-based models to assess the impact on the aircraft flight envelope and controllability. These tools will permit off-line analysis and will facilitate the development of on-board guidance and control algorithms to support NASA goals for greater aircraft resiliency during adverse flight conditions. In Phase I, development and demonstration of a generalized system architecture to identify and assess the effects of aircraft anomalies will be performed, which builds upon previous work toward model-based aircraft upset detection. Phase I demonstrations will include simulation evaluation for a generic transport aircraft and test demonstration for a small unmanned aircraft.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
The primary outcome of this research and development will be design and simulation tools to develop detection algorithms for aircraft anomalies and to assess the impacts of these anomalies on the aircraft controllability and recovery capability, including intelligent flight guidance for potentially degraded aircraft. These methods will form the basis of design toolbox for supporting development of aircraft resilient control and on-board guidance algorithms. Potential NASA applications include development of aircraft anomaly diagnostics and flight directors, which may be integrated with resilient flight control demonstration technology. These technologies support NASA Aviation Safety Program objectives for safe operations during adverse conditions and aircraft anomalies.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
In addition to improving safety of existing and future commercial aircraft systems, the results of this research and development will also benefit general aviation, in particular for aircraft with modern avionics systems. Detection and assessment of a subset of aircraft anomalies and upset conditions may potentially be performed using reduced, low-cost sensor packages. This spin-off technology application may be incorporated into a retrofittable (portable) system, thus permitting development of a stand-alone avionics package that may have broad application beneficial to all general aviation aircraft.

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.
