Piloted Simulation of Fault, Detection, Isolation, and Reconfiguration Algorithms for a Civil Transport Aircraft
2005
Honeywell Labs has been researching and developing together with NASA Langley Research Center (LaRC) algorithms for aircraft failure management and recovery. The algorithms have been integrated into a Control Upset Prevention and Recovery System (CUPRSys) that provides control law reconflguration, fault detection, fault isolation and pilot cueing. This paper describes the capabilities of CUPRSys and the results from an evaluation of CUPRSys by an experimental test pilot in the Integration Flight Deck (IFD) at LaRC. Also included in the paper are details about the IFD and the MATLAB simulation environment used for design. The piloted evaluation was performed at three ∞ight conditions and the results for one representative maneuver are presented. Pilot ratings were obtained for maneuvers for the un-failed aircraft, for the failed aircraft without reconflguration and for the failed aircraft with reconflguration. Only reduction of surface efiectiveness faults were considered. The piloted simulation results suggest that CUPRSys provides a robust control law with promising fault detection, isolation and reconflguration capability.
