An Efficient Method for Incorporating Computational Fluid Dynamics Into Sonic Boom Prediction. Page, J. A. & Plotkin, K. J. In pages 1–16, Baltimore, MD, 1991. \AIAA Paper\ 91-3275. doi abstract bibtex A method has been developed for utilizing Computational Fluid Dynamics (CFD) flow solutions as a starting point for sonic boom propagation calculations. An existing CFD code was shown to predict near-field flew with adequate resolution for sonic boom analysis. However, within the flowfield domain for which this CFD calculation is practical, there can be significant unresolved diffraction effects. Neglecting these effects can underpredict boom at the ground. A matching methodology has therefore been developed, based on an acoustic multipole formulation. The multipole formulation allows a transformation from near-field flow to the final far-field azimuthal pattern. An example of the application of this methodology to a wing-body configuration is presented.
