Prediction of various sonic boom signatures observed in large scale experiment

Results of predicting sonic boom signatures observed in D-SEND#2 flight test are presented in this study. D-SEND#2 flight test was held in northern Sweden in 2015 in order to demonstrate JAXA’s low-boom design concept. The flight test provides three kinds of waveforms: conventional N wave, diffracted U-shaped waveform, and the low-boom waveform. In this study, the method of predicting one or more waveforms above will be introduced.
