technical field [0001] The invention mainly relates to the technical field of satellite ground simulation equipment, in particular to an aerodynamic vector propulsion system of a satellite ground simulation device. Background technique [0002] The spacecraft simulation device is a spacecraft simulation system integrated with hardware and software components according to the composition and structure of a real spacecraft. The spacecraft simulation device can simulate the movement and working state of the spacecraft in space on the ground, such as three-axis translation and rotation. [0003] In order to realize the translation of the simulation device on the experimental plane, an external propulsion system is needed to provide the driving force. At present, jet propulsion is the most widely used ground simulation device for spacecraft. Its principle is to use the change of working medium pressure to generate reverse thrust.

AI Technical Summary

Problems solved by technology

Due to the limited capacity of the gas tanks currently storing high-pressure gas, the working time of the entire jet propulsion system is limited, thereby limiting the working time of the simulation device

In order to obtain a longer experiment time, the capacity of the gas tank must be increased, which increases the volume and weight of the entire simulation device

Moreover, the nozzle generally works in a pulse mode, and the thrust obtained through the nozzle is small, and continuous thrust cannot be obtained, and the long-distance movement of the simulation device cannot be realized
