在法国航空航天局，低压静止电弧射流被用来模拟空间探测器在高超音速进入行星大气层时周围的等离子体流。本文着重于实验研究的物种目前在超音速喷嘴出口处产生的CO2-N2等离子体混合物类似于火星大气中的流。研究了某些自由基内模的热不平衡性以及电子密度和温度。
At Laboratoire d'Aérothermique low pressure stationary arc jets are used to simulate the plasma flow around a space probe during a hypersonic entry into a planetary atmosphere. This paper focuses on the experimental investigation of the species present in the flow produced at the exit of the supersonic nozzle in CO2–N2 plasma mixtures similar to the Mars atmosphere. The thermal nonequilibrium of the internal modes of some radicals is examined together with the electron density and temperature.
