With the progress of the research and application of modem aerospace technology, the development of hypersonic air vehicles has been pushed to a new climax. Now to develop a shape with good aerodynamic characteristics becomes a significant work. As a kind of new configuration waveriders have high lift to drag ratio (L/D) in hypersonic flight, which makes the study of waverider shapes an important trend of hypersonic air vehicles development.In this study a primary method for designing a waverider configuration is developed based on the approximate solution of conical flow fields. The simplified cone-derived shock wave is discussed as the basic model for design. Different shapes designed from different compression angles and basic geometric coefficients at the same Mach number are put into analysis. With a numerical code and a computing software, the aerodynamics characteristics of the shapes are discussed. The feature of the waverider configurations is proved by this work and the analysis of the off-design aerodynamics characteristics is also emphasized in this study. Finally, an experimental model is developed for a wind tunnel experiment to demonstrating the numerical analysis. |
