The overall performance of a scramjet-powered vehicle not only depends on the performance of individual components but also on how the components interact with one another. Because scramjet engines must be integrated into the vehicle design, the opti

Steady-state stagnation temperature probes are used during gas turbine engine testing as a means of characterizing turbomachinery component performance. The probes are located in the high-velocity gas-path, where temperature recovery and heat transfe

The design of a nozzle of an unfueled quasi-axisymmetric scramjet model is optimized for minimum drag for a Mach 8 flight condition. The approach to the nozzle design is to develop a simple force-prediction methodology in an optimization study. The s

The net axial force on a non-fuelled quasi-axisymmetric scramjet model designed for operation at Mach 6 was measured in the T4 Stalker tube at The University of Queensland using a single-component stress wave force balance. The design used was a vari
