Innovative Techniques of Modeling and Simulation for Commercial Derivative Aircraft Upset Recovery

The objective of CTSi’s specific SBIR proposal is to demonstrate that the aerodynamic database for a full-scale transport-category aircraft in upset conditions can be reliably derived from flight tests of an autonomous scale model. The process for extracting the needed aerodynamic database will be prototyped and validated using a scale model of the P-8A aircraft. A major advantage of the CTSi approach is the option to dynamically scale the model. This allows the responses of the model to be compared to the full-scale aircraft for flight conditions that the full-scale aircraft can fly. Because the full-scale aircraft cannot be safely flown in most upset recovery scenarios, the CTSi scale model approach may provide the only means to validate the aerodynamics and control system response that the full-scale aircraft may exhibit.
