A real-time stability margin (RTSM) estimation tool has been developed for in-flight robustness analysis of the X-48B (Boeing Phantom Works, St. Louis, Missouri) blended-wing body. The tool incorporates methods for generating excitation signals and the ability to analyze the open-loop frequency response during flight-testing. The excitation signals are mutually orthogonal and minimize the peak factors to provide multi-input excitation while avoiding excursions in flight condition. For in-flight analysis, an emphasis has been placed on comparison between flight data and simulation data in addition to estimated stability margins.
