A layout design method for coplanar double backup of spacecraft thrusters

Abstract

The invention provides a spacecraft thruster coplanar dual backup layout design method. The spacecraft thruster coplanar dual backup layout design method comprises the steps that eight bent spray pipe thruster A groups and eight straight spray pipe thruster B groups are uniformly installed on one installation plane; and the thruster A groups are arranged at the four vertexes of the installation plane, spray nozzles of the thruster A groups face towards the outer edge of the plane, the thruster B groups are arranged at the centers of the four side lengths of the installation plane and are close to the outer edge of the plane, any bent pipe and straight pipe thruster combined modules are not adjacent and are uniformly distributed in the plane, and each set of modules are spaced by 45 degrees. According to the spacecraft thruster coplanar dual backup layout design method, the problem that thruster layout is limited is solved, too much resource space does not need to be occupied, and the three-axis thrust and the torque which are required by a spacecraft can be provided; three-axis attitude control can be completed; track elevation control is achieved; track lowering and inclination angle adjusting can be conducted through the straight spray pipe thruster B groups after yaw pitching maneuvering; and by means of the bent pipe and straight pipe coplanar edge layout design idea, the influence of jet plume flow is avoided, and a larger available layout space is provided for the spacecraft.

Description

technical field [0001] The invention relates to the field of aerospace vehicle attitude and orbit control, more specifically, a coplanar double backup 16 thruster layout, and a layout design method for realizing spacecraft attitude control and orbit control functions. Background technique [0002] The propulsion subsystem is the main actuator of the spacecraft attitude and orbit control system. Its main task is to provide torque for attitude control; provide thrust for initial orbit adjustment and orbit maintenance; and provide torque for flywheel unloading when necessary. It is an important actuator of the spacecraft. Ideally, the layout of the thrusters can satisfy three-axis attitude and orbit control by arranging pairs of thrusters on different axes and in different planes that do not pass through the center of mass. , sensors and other layout constraints, but also to avoid the influence of the plume, the layout space is limited.
