摘要
对闭式加注系统和开式加注系统特点进行介绍。通过理论计算和公式推导得出,在开式加注系统中,当加注常温易挥发推进剂时,贮箱排出混合气体量对加注精度影响较大,并得出了与贮箱排气量相关的因素,根据这些因素提出了进一步提高加注精度的设想。
The characteristics of open-looped and closed-looped fueling system were introduced. According to theoretical calculation and formulae deduction, the gas exhausted from the filling tank would have a great effect on the weight measurement accuracy when the volatile propellant was filled by open-looped fueling system. Factors about exhausted mass from the filling tank were also gained. Assumptions to improve the weight measurement accuracy were brought forward according to the factors.
