Summary
Some numerical analyses results for predicting the effect of atmospheric turbulence on sonic boom, especially for the waveform observed in the D-SEND#2 flight test, are presented in this paper. The measured sonic boom in the flight test took the shape with a much gentler curve than the predicted one with no effect of atmospheric turbulence. Through some inspections of the flight test, it was found that the effect of atmospheric turbulence has possibility to give reasonable explanation on the deformation of waveform. This paper reports evidence on the latter possibility in detail through some steps: verification and validation by comparing with analytical solution or the result of other preceding researches.
