Abstract

The invention relates to a mechanism for adjusting thrust direction of an electric thruster in a spacecraft, in particular to an orthogonal double-joint electric thruster pointing mechanism. The mechanism includes a rotary actuator Ⅰ, a universal joint ring, an electric thruster, an upper rotating frame, a lower fixed frame and a rotary actuator Ⅱ, wherein the universal joint ring is installed on the lower fixed frame so that the Y axis rotates, and the rotary actuator Ⅱ Set on the lower fixed frame, and the output end of the rotary actuator II is connected with the universal joint ring, and the rotary actuator II is used to drive the universal joint ring to rotate around the Y axis; the upper rotary frame rotates around the X axis and connects with the universal joint The rotary actuator I is set on the upper rotary frame, and the output end of the rotary actuator I is connected with the universal joint ring, and the rotary actuator I is used to drive the upper rotary frame to rotate around the X axis; the electric thruster is set on the upper on the swivel stand. The present invention achieves the purpose of adjusting the rotation of the upper bracket by using a universal joint ring, and can realize the orientation of the upper rotating frame of the mechanism in any direction within the travel range.

Description

technical field [0001] The invention relates to a mechanism for adjusting thrust direction of an electric thruster in a spacecraft, in particular to an orthogonal double-joint type electric thruster pointing mechanism. Background technique [0002] At present, both at home and abroad, whether it is maintaining the position of the spacecraft in orbit or changing the orbit of the spacecraft, the thrust of the propeller is required. Compared with chemical propulsion, electric propulsion has the advantages of high specific impulse, small disturbance, and small mass. Therefore, at this stage, it is a good method to use electric propulsion technology to control the operation of satellites in orbit. How to effectively and accurately control the direction of the propulsion force is an important issue to be studied, which requires an electric propulsion pointing mechanism to control the direction of the propulsion force. Most of the electric thrusters used today are large in size an...
