Abstract

Low sonic boom design method has become one key technology of next generation of supersonic aircraft. The original SGD method can't evaluate the nonlinear effect of sonic boom in near field. The near field pressure distribution is used in inverse design to replace the F function. Near field prediction of sonic boom is based on point to point structured/unstructured hybrid grid, avoiding the difficulty of generating structure grid on complex aircraft configuration and improving the analysis efficiency. The results demonstrate that the low boom configuration based on the new inverse design method has lower sonic boom overpressure and perceived level of loudness than low boom configuration based on original SGD method.
