| Abstract | A design methodology employed for a practical preliminary-level integration of next generation hypersonic airplanes is presented in this paper. The key feature of this type of configurations is that the forebody of the vehicle is designed by rotating and assembling two waverider-based-surfaces, which are defined by linear edges. The propulsion system assumes two scramjets with cylindrical combustion chambers. The layout of the configuration presents a Blend-Wing-Body aircraft in order to integrate the airframe and the propulsion units as well as to improve the aerodynamic performance. A 7.2 m long, Mach 6 vehicle is presented, and multi-point aerodynamic performance predictions are carried out by using computational fluid dynamics with a fully turbulent model at the flight Mach numbers range from 4 to 7, the flight angles of attack range from 0 to 8 degree, and the flight altitudes range from 20 km to 29 km. Numerical results demonstrates that such a design of the forebody could produce a good quality flowfield for the scramjets. Moreover, a relatively high lift-to-drag ratio can be obtained. The maximal values vary from 3.75 to 3.31 when the flight Mach number/altitude vary from 4/20 km to 7/29 km. © 2015, American Institute of Aeronautics and Astronautics. All rights reserved. |
