Optical spectroscopy investigation of N₂-CH₄ plasma jets simulating Titan atmospheric entry conditions

Ndiaye, A. A.; Lago, V.

Planetary probes penetrating at supersonic speed into high atmosphere require the development of composite materials for thermal protection of the surface exposed to a high enthalpy flux. Rarefied arc plasmas can be used to simulate the atmospheric re-entry plasmas. The aim of this paper is to describe the latest results of optical emission measur…
