SONIC booms have been the main obstacle for supersonic flight over inhabited areas. The minimization of the environmental impact is one of the fundamental issues to be resolved to make commercially viable supersonic flight a reality: recent studies have shown that supersonic aircraft would have great market potential, should they be allowed tofly supersonically over land [1, 2]. For these reasons, research efforts have been recently focused on various techniques for sonic boom mitigation,[3–7] and nonlinear computational fluid dynamics (CFD) has emerged as an essential tool owing to the requirement for accurate boom and performance information and the increasing availability of large computing resources. At the same time, it must be noted that single-minded efforts to reduce the boom loudness typically result in aerodynamic performance shortcomings that translate into reduced range or payload, longer …
