Sonic Boom Focusing Prediction and Delta Wing Shape Optimization for Boom Mitigation Studies
, 2007 Supersonic travel over land would be a reality if new aircraft are designed such that they produce quieter ground sonic booms, no louder than 0.3 psf according to the FAA requirement. An attempt is made to address the challenging goal of predicting the sonic boom focusing effects and mitigate the sonic boom ground over pressure for delta wing geometry.

Sonic Boom Prediction Using Euler/Full Potential Methodology
, 2005 Sonic Booms of two different bodies, a double cone configuration and a modified F-SE aircraft, are predicted using Euler solvers for the near field, and a Full Potential Propagation method for the far field. The problem is considered inviscid since viscous effects in high Reynolds number flows are negligible in Sonic Boom propagation.

Prediction of sonic boom overpressures near lateral cutoff [PDF]
The Journal of the Acoustical Society of America, 1992 Two methods of sonic boom predictions are used to compare predicted overpressures to measured sonic booms to quantify the effects of weather and flight variability on the lateral propagation of the booms. The sonic boom measurements were collected by the US Air Force at Edwards AFB, CA using a variety of supersonic aircraft.
