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 configurations with shocks attached to or detached from 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 Küchemann's partial speculation on the conical flow field structures of this type, and also find a new conical flow field structure. Finally, we briefly describe the preliminary results in an ideal gas and present a new model for the problem of supersonic flow past a body.
