| Abstract: | The aerodynamic characteristics of the airframe/scramjet engine integrated waverider is studied by numer- ical simulation. The paper simulates the three- dimensional viscid flow field of airframe/scramjet engine integrated waverider forebody, by computing Reynolds averaged Navier- Stokes equations with cell center type finite volume method. A hypersonic pressure experiment is made to validate the result of simulation. The results of experiment and computation show that：the simulation agree with the test date;waverider- derived hypersonic vehicle be characterized by high lift and low drag and high lift - drag ratio ; the pre- compressive performance of the forebody can satisfy the requirement of the in- let and it keeps good aerodynamic characteristics. |
