| Sumario: | Simulating the propagation of the sonic-boom precisely from the near-field of a supersonic airplane down to the ground level is not easy. It requires numerical schemes that preserve the large-time properties of the model. In this article we deal with an optimization and inverse design problem related to the sonic-boom minimiza-tion. In particular, we emphasize the key points that need to be handled in order to keep the efficiency of the approximations of its solution; Hegazkin supersonikoek eragindako soinu-eztandaren hedapena eremu hurbiletik lurreraino zehatz-mehatz simulatzea ez da erraza. Ereduaren denbora-tarte handietarako propietateak babesten dituzten zenbakizko metodoak behar dira. Artikulu honetan, soinu-eztandaren minimizazioarekin erlazionaturik dagoen optimizazio eta al-derantzizko diseinu-problema ikertu dugu. Bereziki, bere soluzioaren hurbilketen era-ginkortasuna mantentzeko gakoak ematen ditugu. |
