摘要

This paper presents a novel wide range adaptable hypersonic dual-waverider integrative design method based on two different types of 3D inward-turning inlets, which were respectively chosen by streamline tracing directly with elliptical entrance(inlet EBI) and cross-section controllable from sector entrance to circle exit(inlet CSI). For aerodynamic characteristics of the related integrative hypersonic vehicle configurations of TED-HV(EBI) and TSD-HV(CSI), the numerical results show that both inlet EBI and CSI have a good performance at the on-design Mach number 6.0 with nearly full flow capture, and the throat total pressure recovery coefficient of EBI(0.613) is 16.82% much higher than CSI's(0.525) that it will bring a better internal flow performance and larger thrust for vehicle TED-HV; the maximum L/D of integral configuration(including internal flowpath) of TED-HV is about 4.6, while that of TSD-HV can approximately reach 5.1, thus, TSD-HV owns a superior aerodynamic force performance than TED-HV. However, the lift and drag coefficients of TED-HV are both significantly higher than TSD-HV that it will not only be more available for the payload under hypersonic cruising, but also needs more thrust power to match the larger drag. Furthermore, TED-HV is much more pitching unstable than TSD-HV by the strong shock wave effects of the special "Λ" typed waverider forebody.
