Type: article
Abstract: A method for rapid estimations of supersonic civil aircraft sonic boom characteristics in standard atmosphere is proposed. The piece-wise linearity of the temperature profile and the absence of atmospheric wind allow to completely reduce the problem on the geometry of the propagation of sonic boom waves to an algebraic form. For acoustic pressure, an exact solution is formulated on the basis of the approach of nonlinear geometric acoustics. The dependence of the geometry of the sonic boom waves propagation on the parameters of the aircraft cruise flight is analyzed. Under the conditions of the third seminar SBPW (Sonic Boom Prediction Workshop) 2020, ground overpressure signatures from the X-59 demonstrator were calculated.
