TL;DR: In this paper, a thermal response, pyrolysis, and ablation model was developed to evaluate the performance of multilayer Felt Reusable Surface Insulation at high temperatures.
Abstract: Felt Reusable Surface Insulation was used extensively on leeward external surfaces of the Shuttle Orbiter, where the material is reusable for temperatures up to 670 K. For application on leeward surfaces of the Orion Multi-Purpose Crew Vehicle, where predicted temperatures reach 1620 K, the material functions as a pyrolyzing conformal ablator. An arcjet test series was conducted to assess the performance of multilayer Felt Reusable Surface Insulation at high temperatures, and a thermal-response, pyrolysis, and ablation model was developed. Model predictions compare favorably with the arcjet test data

TL;DR: In this paper, the authors compare hydrogen atom number density, velocity, and temperature measurements with DSMC predictions at nozzle exit for two power levels of a hydrogen arcjet thruster: 1.34 kW and 800 W.
Abstract: : We present comparisons between hydrogen atom number density, velocity, and temperature measurements with DSMC predictions at nozzle exit for two power levels of a hydrogen arcjet thruster: 1.34 kW and 800 W. Comparisons between model and experiment are also presented in two downstream plume regions. Atomic density peaks at each power are not seen to vary substantially while velocity and temperature maximums decrease with lower-power operation. Changes in profile shapes are noticed at the different powers and similar profile changes are also observed in the model predictions. Differences in overall magnitude are observed at some locations between measured data and predicted results, but in general the model matches the measured data quite well.

TL;DR: In this article, an experimental study of the measurement of cathode temperature, current distribution, and near-cathode electron number density in a high power hydrogen arcjet is presented, motivated by the desire to better understand arc-electrode interactions in arcjet thrusters.
Abstract: Abstract : An experimental study of the measurement of cathode temperature, current distribution, and near-cathode electron number density in a high power hydrogen arcjet is presented. This study is motivated by the desire to better understand arc-electrode interactions in arcjet thrusters, which in many cases, is the main determinate of arcjet lifetime. Measurements such as these may also provide the needed boundary conditions for numerical arcjet simulations, presently under development. We describe in this paper the application of a non-intrusive in-situ measurement technique for on-axis, spectral imaging of the electrode region of arcjets, and the application of this technique to the measurement of the cathode and anode temperatures, cathode spot size, and current distribution in a 30kW hydrogen arcjet thruster. A relatively large field of view (twice the throat diameter) and high spatial resolution (9 micrometers) are achieved.
