Numerical solutions of 3D Euler equations are obtained for supersonic flows, in order to investigate the sonic boom pressure signatures in the near field. The models used in the calculations are a body of revolution and two wing-body configurations. The results for a body of revolution indicate a good agreement with the experimental data. A solution-adaptive-grid method which uses tension and torsion spring analogies is applied. The results show that this method improves the accuracy of solutions, and that the sharper pressure signatures can be calculated than those in initial grid.
