在低压（0.13毫巴）的固定电弧加热发动机被用来模拟的气体流动的车辆在进入土卫六和火星的大气层的属性。土卫六的大气模拟使用了99%的N2和1%的CH 4的混合气体，火星的大气模拟使用了97%的CO2和3%的N2的混合气体。应用两种不同的测量技术来表征等离子体：1）光学发射光谱和2）质谱。得到了不同等离子体的组成、电离和中性成分的轴向和径向粒子分布以及振动和转动温度。为了确定的温度进行了CN的分子能带结构的数值模拟。
A stationary arcjet at low pressure (0.13 mbar) is used to simulate the properties of the gas flow around a vehicle during entry into the atmosphere of Titan and Mars. For simulation of the Titan atmosphere, a gas mixture of 99% N2 and 1% CH 4 was used, and for the Martian atmosphere, a gas mixture of 97% CO2 and 3% N2 was used. Two different measurement techniques are applied to characterize the plasma: 1) optical emission spectroscopy and 2) mass spectrometry. The composition of the different plasmas, the axial and radial particle distributions of ionized and neutral components, and the vibrational and rotational temperatures were obtained. For the determination of the temperatures a numerical simulation of the molecular band structures of CN was carried out.
