Zero-counterweight barycenter deploying method for parallel tiling tank satellite

Abstract

The invention provides a zero-counterweight barycenter deploying method for a parallel tiling tank satellite. The method comprises the following steps: (1) preliminarily calculating a satellite barycenter position; (2) preliminarily calculating an adjustable scope of a barycenter; (3) after testing mass characteristics of the satellite, acquiring a measured value of the barycenter, analyzing and calculating the mass and position of a to-be-adjusted propellant according to the measured value, and causing the barycenter to approach to the original point; (4) performing propellant filling for the satellite according to a calculating result of the filling quantity of the propellant of each tank, controlling different filling quantities, and meanwhile, setting a work state after filling. The invention provides the new barycenter deploying method for a parallel tiling tank layout high-orbital satellite; under the condition of not increasing the total mass of the satellite, the original barycenter offset of the satellite is reduced, so that the barycenter variation of a satellite orbital transfer section is reduced, the disturbance torque is reduced, the safety of the satellite orbital transfer is ensured, the consumption of the propellant is reduced, and the service life of the satellite is prolonged.

Description

technical field [0001] The invention relates to the general technical field of satellites, in particular to a zero-counterweight centroid allocation method for a high-orbit satellite that adopts a parallel layout of storage tanks. Background technique [0002] After the high-orbit satellite is separated from the satellite, it generally uses the apogee engine that comes with the satellite to ignite, and after several orbit changes, it reaches the predetermined orbit. During this process, with the consumption of propellant, the center of mass of the satellite is constantly changing, and the thrust of the engine cannot pass through the center of mass at all times, thus generating disturbance torque. The existence of the disturbance moment has two main influences on the satellite. On the one hand, it affects the life of the satellite, and it needs to consume propellant to generate control torque to offset the disturbance torque; on the other hand, it affects the safety of orbit...

Problems solved by technology

[0011] At present, the domestic high-orbit satellites in orbit do not adopt the parallel layout of storage tanks, and several satellite models under research adopt the parallel layout of storage tanks, but no similar centroid allocation technology or reports have been found
