报告摘要：In this talk, we will present the research progress on the problem of supersonic flow past a delta wing in a Chaplygin gas, including attached and detached shocks to the leading edge. Moreover, we focus on its application in the study of Nonweiler wing, which is a class of the simplest waveriders. Mathematically, this problem can ultimately be reduced to a boundary value problem of a degenerate elliptic equation. Using the intrinsic structure of the equation and the continuity method, we showed that the problem admits a global self-similar solution. Our results verify K\uchemann's partial speculation on the global conical flow field structures of this type.
