Experimental investigation of hypersonic buzz on a high cross-range shuttle configuration [PDF]

open access: yes
A wind tunnel investigation has been conducted to determine the nature of an unsteady hypersonic flow phenomenon, often referred to as hypersonic buzz, on a 1:100 scale model representative of a high cross-range shuttle configuration.

The shock waves in decaying supersonic turbulence [PDF]

open access: yesarXiv, 2000
We here analyse numerical simulations of supersonic, hypersonic and magnetohydrodynamic turbulence that is free to decay. Our goals are to understand the dynamics of the decay and the characteristic properties of the shock waves produced. This will be useful for interpretation of observations of both motions in molecular clouds and sources of non ...

Prediction of forces and moments for flight vehicle control effectors. Part 1: Validation of methods for predicting hypersonic vehicle controls forces and moments [PDF]

open access: yes
Many types of hypersonic aircraft configurations are currently being studied for feasibility of future development. Since the control of the hypersonic configurations throughout the speed range has a major impact on acceptable designs, it must be ...

Some consequences of non-local-equilibrium in hypersonic aerodynamic flows [PDF]

open access: yes, 2005
In simulating high-speed, high-altitude aerodynamics it is important to be able to capture physical phenomena that are due to the non-local-equilibrium nature of the rarefied gas flow (this is in addition to any effects due to dissociation, ionisation ...
