Review of Sonic Boom Prediction and Reduction Methods for Next Generation of Supersonic Aircraft

open access: yesAerospace, 2023
The reduction of sonic boom levels is the main challenge but also the key factor to start a new era of supersonic commercial flights. Since 1970, a FAA regulation has banned supersonic flights overland for unacceptable sonic booms at the ground, and many
