Abstract: ffect of arrangements of a pressure-feed, liquid propellant space engines system on centroid drift of a spacecraft was studied in this paper. A mathmematical model for calculation of the centroid drift was given.Some important conclusions of the arrangements for a liquid propellant space engines system were obtained.
