为了实现低温推进剂的长期在轨贮存，保证推进剂从贮箱到发动机的液态供应，拟采用热动力排气系统（Thermodynamic Vent System，TVS）来实现推进剂的热管理。以单位长度液氧管路为例，阐述了热动力排气系统的原理，进行热动力排气系统孔板及TVS管路设计、在轨贮存时间计算、TVS管路排放量计算以及排放量影响因素分析。

To achieve long-term on-orbit storage of cryogenic propellant and ensure the feeding of liquid propellant from tank to engine, the Thermodynamic Vent System (TVS) was used to achieve heat management initially. Taking a liquid oxygen line in unit length as an example, the theory of TVS was expounded, the orifice and TVS line of the TVS were designed, and the on-orbit storage time and mass flow of TVS line were calculated. At last, the factors that affected mass flow were analyzed.
