Abstract

The invention provides a 16-thruster layout designing method of an omnidirectional orbital transfer spacecraft. The method comprises the following steps: (step A) forming a group of thruster combined modules by using four thrusters according to a method of uprightly mounting three thrusters and obliquely mounting one thruster; (step B) laying four groups of thruster combined modules at four opposite angles of a satellite, wherein any two groups of thruster combined modules are not adjacent to each other; and (step C) configuring two sets of independent branch pipelines, so that eight thrusters in the 16 thrusters share one set of pipeline and the rest eight thrusters share the other pipeline. According to the invention, a thruster layout scheme of a 16-thruster full-orbit motor spacecraft with optimized angle layout is designed; therefore, three-axis and six-direction thrust force can be provided, posture control and orbit control backup functions are obtained, no area center is occupied by angle layout design, and a larger layout space is provided for a star catalogue single machine.

Description

technical field

[0001] The present invention relates to the field of spacecraft attitude and orbit control, especially a 16 thruster layout design that can provide three-axis and six-direction thrust and satisfy omnidirectional orbital maneuvering, specifically a 16 thruster that can change orbit in all directions. Thruster layout design method. Background technique

[0002] As an important part of the satellite attitude and orbit control system, the thruster generally cooperates with multiple ones to complete the attitude damping, attitude control, flywheel unloading, and orbit maintenance after the satellite enters orbit and the satellite is separated by ejecting the reaction force and moment of the working medium. , track maneuvering and other functions.

[0003] Most of the existing spacecraft are designed for one-time use. In order to ensure the service life, the subsystems usually adopt redundant design. On the other hand, due to cost and weight constraints, there ca...
