Problems solved by technology

Functions such as auxiliary orbit change, fuel supply, and fault repair belong to the multi-mission aircraft of the on-orbit operation category. It can perform a series of operations such as space fault troubleshooting and prolonging the life of the service object, all of which require close contact with the service object and Forming an assembly with the service object for on-orbit position maintenance requires that the thruster layout of the multi-mission aircraft not only meet its own requirements but also ensure that the service object will not be affected after the assembly is formed, and the position protection method of the assembly and The strategy is also related to both. The layout of the existing thruster will interfere with the service object, the plume of the thruster will affect the service object, and the position of the assembly cannot be guaranteed. The existing satellite thruster is used The calculation method can no longer meet the requirements of multi-mission aircraft

Embodiment Construction

[0052] Below in conjunction with accompanying drawing, specific implementation method of the present invention is described in detail:

[0053] In order to distinguish it from orbit-changing engines, thrusters are defined as small-thrust thrusters used in groups on aircraft, mainly used for star attitude control during orbit change of aircraft, orbital position and attitude control during orbit, etc. The basic attributes of the thruster during layout include the thruster field distribution model, the thruster plume thermal influence model, the thruster plume force influence model, etc. The thrust of the thruster used by the aircraft is defined here as F=10N. In order to maintain the thrust and moment balance, the thrusters are generally designed to be used in pairs or groups in the design stage. Each pair of thrusters can complete a thrust in a displacement direction or a rotation. direction of moment.

[0054] Such as figure 1 As shown, a specific embodiment of the thruster...

Abstract

The invention relates to a thruster layout of an aircraft and an aircraft position protection method based on the layout and belongs to the field of high-orbit satellite design. The aircraft provides20 thrusters which divided into two branches, each branch comprises 10 thrusters, and each branch can independently complete six-degree-of-freedom attitude and orbit decoupling control of a service aircraft and south-north and east-west position keeping and attitude control of an assembly. Each position protection mode provided by the invention comprises backup, and for the selection of the backup, a formula related to the centroid height of the assembly and the thrust angle of the multi-task aircraft thruster is adopted to calculate the position protection efficiency, so that the highest efficiency of the selected position protection mode is ensured.

Description

technical field [0001] The invention belongs to the field of high-orbit satellite design, and in particular relates to a thruster layout of an aircraft and an aircraft position guarantee method based on the layout. Background technique [0002] After being in orbit, multi-mission aircraft can work independently or perform in-orbit combined operation. With the development of aerospace industry, multi-mission satellites with different configurations have emerged as the times require. The advantages of multi-mission satellites are mainly to reduce the risk of satellite mission failure, reduce mission costs, enhance mission system functions and improve mission flexibility, etc., which are of great significance in terms of economy, national defense and the promotion of space technology development. Functions such as auxiliary orbit change, fuel supply, and fault repair belong to the multi-mission aircraft of the on-orbit operation category. It can perform a series of operations s...
