This paper presents an overview and analysis of the various aspects of hypersonic ground
testing. For this, first the simulation requirements according to the different flow regimes of …

Abstract The T6 Stalker Tunnel is a multi-mode, high-enthalpy, transient ground test facility. It
is the first of its type in the UK. The facility combines the original free-piston driver from the …

Shock tubes are a crucial source of experimental data for the aerothermodynamic modelling
of atmospheric entry vehicles. Notably, many chemical-kinetic and radiative models are …

A new reflected shock tunnel capable of generating hypersonic environments at realistic
flight enthalpies has been commissioned at Sandia. The tunnel uses an existing free-piston …

A set of magnetohydrodynamic (MHD) aerobraking experiments was conducted with the aim
of simulating the Earth reentry environment for Mars return trajectories, and to study the …

Shock tube experiments are a cornerstone of investigations into the hypersonic flight
environment. However, the actual flow through the basic shock tube has not been well …

Using a Lagrangian solver, thermochemical nonequilibrium simulations are performed for
the entire range of practical operating conditions of expansion tubes to isolate the influence …

Thermochemical nonequilibrium in expansion tunnel nozzles is investigated numerically
using a state-to-state description in one dimension for representative air conditions. Limiting …

Shock tube flows can be used to investigate nonequilibrium thermochemistry and radiative
processes found in hypersonic flows. The flow in a shock tube contains many flow …

Traditionally, expansion tube test times have been experimentally evaluated using test
section mounted impact pressure probes. This paper proposes two new methods which can …
