The motivation for the work is the need for an improved ability to predict takeoff noise of future commercial supersonic aircraft. The overall objective is to validate as well as improve the conversion of facility scale-model data and semi-empirical jet-noise predictions to flight noise. As a first step, the processing of data and results from an acoustics flight test are described. The next step involves the comparison of the flight acoustic data and complementary rig-test results. This will be presented in future reports. Ultimately, the goal is improved noise-prediction methods for system studies of future commercial supersonic aircraft.
