推进系统并联贮箱均衡排放性能及其控制措施

推进系统在工作过程中,贮箱排放的不均衡性将引起飞行器质心偏移,产生干扰力矩。对空间推进系统并联工作的金属膜片贮箱均衡排放的影响因素进行了分析,结合均衡排放的控制措施对某型号推进系统工作过程中的排放不均衡量进行了预计,并与飞行试验结果进行了比对。飞行试验结果表明控制措施可行、有效。

Equalizing expulsion and control of parallel tanks in propulsion system

The propellant tank is an important component of the space propulsion system.During the operation of the propulsion system,the unequal expulsion of the metallic diaphragm tanks will lead to the variation of the spacecraft centroid,which will result in interference moment.The factors which affect the equal expulsion of parallel metallic diaphragm tanks in the propulsion system are analysed.The unequal expulsion degree of a propulsion system is estimated in combination with the measures of controlling the expulsion.It is compared with the results of flight experiment.The results show that the control measure is feasible and effective.
