The invention provides a method of a large-scale thrustor on a simulation spacecraft and a device thereof. The invention uses an air flotation three-axle table to simulate the body of a spacecraft. A control moment is formed by the push power generated by a plurality of small scale thrustors installed in different directions of the air flotation three-axle table. When the three-axle table works, namely when the spacecraft operates in orbit, the push power generated by small scale nozzles in all directions of the table drives the spacecraft to a target position according to a control instruction. In virtue of the design principle of equivalent scaling, the simulation of the control function of a large scale thrustor on a real spacecraft can be realized. The method is applicable to all situations that the air flotation tables are used for simulating the operation of the spacecraft in orbit and can lower the cost of ground simulation verification of the thrustor technology on the spacecraft.
Description
(1) Technical field [0001] The invention relates to a simulation verification method, in particular to a technology for simulating all large thrusters on a spacecraft. (2) Background technology [0002] The full physical simulation of the satellite control system is a unique simulation method in the process of satellite development. It uses the air-floating three-axis turntable as a motion simulator, also known as air-floating table simulation. The full physical simulation of the satellite control system uses the air-floating three-axis turntable to simulate the satellite body as the control object, and the control system uses the satellite control system for simulation. When a space vehicle performs a full-physics simulation, it is necessary to simulate important space environments such as weightlessness or no resistance on the ground. [0003] The air-floating three-axis turntable uses compressed air to form an air film between the air-floating bearing and the bearing sea...
