The research work objective is to provide a means for analyzing and extending current methods of gathering simulation and in-flight assessments of helicopter flight tasks and maneuvers through application of task performance math models. Simulation tasks are conducted on NASA AMES Vertical Motion Simulator VMS.|
|1997 - 1998 University of California Davis, CA, USA|
|Post Graduate Researcher|
|The research is conducted by Prof. R. Hess, project funded by NASA Ames research center, Moffett Field, CA.
A model-based methodology for assessing flight simulator fidelity in closed-loop fashion is exercised in analyzing rotorcraft low-altitude maneuvers for which flight test and simulation results were available.
The project includes the development of a comprehensive computer program using (MATLAB/SIMULINK), for the design of vehicle-pilot model dynamics. The program was capable of predicting the HQSF (Handling Qualities Sensitivity Function) and PIO (Pilot Induced Oscillation) ratings. The research efforts have resulted in some publications as well as the development of (PVDnl), an interactive computer program for modeling the human pilot in single axis tracking tasks. The program have been distributed to approximately 20 research organizations world-wide, such as Boeing, NASA Ames, NASA Langley.
