Axial forces on quasi-axisymmetric scramjet models designed for operation at Mach 6 and Mach 8 were measured in the T4 Stalker tube at The University of Queensland using a single component stress wave force balance. A Mach 6 nozzle was used. The nozzle supply enthalpy was varied from 3 to 9 MJ/kg and the nozzle supply pressure from 35 to 45 MPa. As the conditions varied, the Mach number varied from 5.7 to 6.7. For both test models, the drag coefficients decreased with increasing Mach number. However, significant differences between the models were not observed over a range of free stream Mach numbers. A theoretical procedure to calculate the drag coefficient was found to give good agreement with experiments when appropriate account was taken of flow spillage at the intake.
