Description
In the plasma wind tunnel facilities PWK1/2 and PWK4 of the Institute of Space Systems, the high-enthalpy flow field is generated using electric arc-jet generators. A sample positioned downstream of the nozzle is thus exposed to a combination of radiative, convective, and chemical heating from the plasma flow, but potentially also from radiation originating from the generator. Assessing the amount of heating due to each of those contributors is vital for thermal protection system development. For hydrogen-helium plasma flows, the amount of radiative heating experienced by a probe in a PWT is unknown. This work will provide first experimental data measured with a radiometer incorporated into a water-cooled copper probe.
Summary
With this work we will provide some first radiative heating data from hydrogen-helium plasma flows in a PWT facility. The experimental approach will utilise a water-cooled radiometry probe in the plasma wind tunnel facility PWK4.
