Upset Prevention and Recovery for Unimpaired and Impaired Aircraft

The proposed project will develop and deliver a software system that integrates tools required for a complete analysis of loss-of-control incidents. The system will include a graphical user interface that provides easy access to symbolic and numerical computing tools that support aircraft modeling, nonlinear dynamic analysis and control analysis; sophisticated data base management; and visualization. We also propose and will implement an innovative methodology and associated computer tools for analysis and control synthesis in the context of upset prevention and recovery for unimpaired and impaired aircraft. Our approach will address: aerodynamic modeling of aircraft operating outside of the normal flight envelope, multi-mode operation of aircraft, automated assembly of analytical and simulation models – including real time models, analytical methods and tools for identifying conditions for departure from controlled flight and identification of 'safe' operating states, and analytical methods and tools for identifying the set of recoverable states and associated recovery strategies. The goal is to provide easy to use, verifiable design software to improve commercial flight safety.
