Scramjets and shock tunnels—The Queensland experience [PDF]
Progress in Aerospace Sciences, 2005 This article reports on the use of a shock tunnel to study the operation of scramjet powered configurations at sub-orbital velocities above 2 km/s. Thrust, as given by a net thrust equation, is used as a figure of merit throughout the study. After a short description of the shock tunnel used and its operating characteristics, experiments on the ...

Influence of Geometric Parameters on Intake Performance of 3D Ramp‐Type Scramjet Inlet
International Journal of Aerospace Engineering, Volume 2024, Issue 1, 2024.The methods based on the assumption of inviscid flow are typically used for the initial design of the scramjet inlet geometry, but the presence of a viscous boundary layer can degrade the validity of the results and lead to nonoptimal operation. This study explored the design space of three‐dimensional ramp‐type scramjet inlet geometry and investigated

Thrust performance of the rocket-based combined-cycle engine under ejector mode
AIP Advances, 2023 The Rocket-Based Combined-Cycle (RBCC) engine integrates the preponderance of ramjet and rocket engines. It can perform excellently at a lower Mach number than a ramjet while consuming less fuel than the rocket.

Radiation Modeling of a Hydrogen Fueled Scramjet [PDF]
Journal of Thermophysics and Heat Transfer, 2011 against a three-dimensional ray tracing method. The radiative species considered are H2O and OH. The radiative heat ux is on the order of 10 kW/m 2 , which is 0.1-0.2% of the total convective wall heat ux. Flow cooling due to radiation is found to be on the order of 2 K.
