In this research, a new type of supersonic transport (SST) configuration is investigated that can contribute to improve aerodynamic as well as noise (sonic boom) performances, by generating supplemental lift force from generated shock waves. Inspired by the previous study of a cone-derived waverider conceptual design that achieved a significant increase in of lift-to-drag ratio (\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$L/D$$\end{document}), a concave study is examined on the waverider (supersonic) configuration. The main purpose of this study is to increase \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$L/D$$\end{document} value as well as to reduce the sonic boom strength by designing the lower side of the waverider configuration. The effect of the concave shape added on the bottom side of the body is examined in this study. The numerical simulation approaches are used to evaluate the objective performance functions of \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$L/D$$\end{document} and sonic boom strength. As a result, the effect of the concave shape added on the lower surface of the body influences the sonic boom strength. Various types of concave models are examined and important design knowledge for the waverider configuration is extracted. Strong shock waves on the lower side of the body cause high-pressure regions to generate higher lift force, and its efficiency depends on the concave position and/or size.
