Implementation of a state-to-state analytical framework for the calculation of expansion tube flow properties
This paper presents a validated and comprehensive analytical framework for the simulation of an expansion tube facility that identifies central flow processes and models them from state to state through the facility using established compressible and isentropic flow relations, and equilibrium and frozen chemistry.

Radiation from simulated atmospheric entry into the gas giants
When entering a gas giant, the heat transfer to the surface of the entry vehicle is primarily driven by radiation from the shock layer. It is not currently known how existing techniques used toExpand

Magnetohydrodynamic drag force measurements in expansion tunnels using an accelerometer-based force balance
An accelerometer-based force balance has been used to measure the magnetohydrodynamic (MHD) drag force which arises when a magnetic field is present in a high-enthalpy ionised flow. This has beenExpand

Using optically filtered high-speed imaging to characterise expansion tube operating conditions
Traditionally, Pitot rake test models have been used to take time- and spatially resolved impact pressure measurements in impulse facilities for flow characterisation. When expansion tubes are usedExpand

Limits of Simulating Gas Giant Entry at True Gas Composition and True Flight Velocities in an Expansion Tube
Atmospheric entry to the Gas Giants involves velocities of the order of 20 - 50 km/s, which is mostly beyond the capabilities of current ground testing facilities. This paper details an investigationExpand

Free-piston driver performance characterisation using experimental shock speeds through helium
Tuned free-piston driver operation involves configuring the driver to produce a relatively steady blast of driver gas over the critical time scales of the experiment. For the purposes of flowExpand

Development of a fast-response calorimeter heat transfer gauge for hypersonic ground testing
A robust, fast response calorimeter based heat transfer gauge called the Diamond Heat Transfer Gauge (DHTG) has been developed for use in transient hypersonic ground test facilities. DesirableExpand
