系留气球内囊氦空二元气体浓度分布特性试验研究

Research on tethered balloon's helium concentration distribution experiment

长期的氦气漏损和空气渗透使得体积一定的系留气球剩余浮力下降,为保证系留气球安全性,必须进行氦气提纯。为了提高氦气纯化的费效比,有必要开展系留气球内囊氦气的气体浓度分布规律研究。基于系留气球内囊气体的组成分析和系统技术指标要求,文中提出了一种适用于系留气球内囊氦气浓度分布特性研究的试验,给出了详细的试验方法并分析试验结果。

Long - term helium leakage and air infiltration makes the volume of a certain residual buoyancy tethered balloon drop. To ensure the safety of tethered balloons, helium must be purified. In order to improve cost - effectiveness of purified helium, the research on tethered helium balloon of gas concentration distribution was needed. In this paper, According to Tethered balloon＇s composition of the gas within the envelope and system technical requirements, A test for helium coneentratign distribution within the envelope was improved, which gave a detailed analysis of test methods and test results.
