Abstract:
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
