Waverider Design Using Osculating Method

Liu, Chuanzhen / Bai, Peng

Because of the requirements of payload capability, flight range, and maneuverability, hypersonic aircraft demand high aerodynamic performance. Waveriders have attracted significant attention because of their high lift-to-drag ratios in hypersonic states. Many methods to design waveriders have been proposed for more than 60 years, among which the osculating method features unique advantages in terms of design space, efficiency, and flexibility. Moreover, nearly all waverider design methods can be realized using this approach. This paper presents an overview of research on waverider design methodologies using osculating theory developed until 2023. The design theory and detailed implementation of the osculating cone method are first described, followed by the progress and improvement of the method and the derived osculating flowfield method. The planform-customized waverider from the osculating cone method, which has developed rapidly in recent years, is discussed emphatically. In addition, the connection between the osculating cone and other waverider design methods is plotted to show its powerful applicability. The application of the osculating waverider in practical aircraft design is also summarized. Finally, some perspectives and suggestions for future development are concluded.
