Abstract:

The integration design method for the novel curved cone waverider forebody inlet (CCWI) is introduced, and a prototype CCWI is designed. The practical CCWI with rectangle exit isolator and leading edge bluntness is obtained under geometrical constrains. The cutting off and bluntness effects are evaluated using the validated numerical simulation tools. Reynolds average Navier-Stokes simulations are conducted at free stream Mach number Ma=4.0, 6.0, angle of attack (AoA) from -4° to 8°. The results show that the practical CCWI has high mass flow capture ratios and total pressure recovery at the simulation conditions. Its basic compression characteristics can meet the needs of scramjet combustors. The present study provides the possibilities for the integration study of CCWI with hypersonic vehicles and scramjet combustors.
