摘要
航天器飞行过程中,并联贮箱内同种推进剂排放不均衡会引起航天器的质心变化。为控制并联金属膜片贮箱的排放不均衡量,对并联金属膜片贮箱均衡排放控制措施进行了理论分析和试验研究,得出了一种能够有效控制并联金属膜片贮箱均衡排放的措施,采用该措施对某典型金属膜片贮箱不均衡量进行了理论计算。为验证并联金属膜片贮箱的均衡排放性能,根据金属膜片的选配原则选取金属膜片进行地面试验验证,并将理论计算结果与试验结果进行比对,结果表明,并联金属膜片贮箱不均衡量计算及控制措施正确、有效。
In the flight process of spacecrafts, the unequal expulsion of same type propellant in the parallel metal diaphragm tank will lead to the variation of the spacecraft centroid. In order to control the expulsion disequilibrium of parallel metal diaphragm tanks, the theoretical analysis and experimental research on control measures for the equal expulsion of parallel metal diaphragm tank were performed. An efficacious measure to control the equal expulsion of parallel metal diaphragm tanks was achieved. The theoretical calculation for expulsion disequilibrium of a typical metal diaphragm tank was carried out with this measure. To verify the unequal expulsion performance of the paralleled metal diaphragm tanks, a ground test was carried out, in which the metal diaphragms were selected according to the matching principles of the metal diaphragms. The theoretical results are compared with the results from the experiment. The comparison result shows that the calculation and control measures are feasible and effective.
