[0111] First, the rudder surface movement assembly 4 drives the rudder surface 4-1 to the desired attitude angle and keeps it fixed through the servo body 4-9 and the connecting rod assembly.

By adjusting the screw nut 1-3-3 in the adjusting component 1-3, as the screw nut 1-3-3 rotates, the spiral pair in the adjusting component 1-3 works, thereby driving the rudder base 3 connected by the screw 1-3-4 to rotate with the rotating pair composed of the ear hinge mounting ear 1-5 in the fixed platform 1. By adjusting the length of the adjusting component 1-3, the rotation of the rudder base 3 relative to the fixed platform 1 can be achieved.
[0113] Finally, by measuring the rotation angle θ of the rudder surface 4-1 relative to the rudder surface base 3, and then reversely adjusting the rotation angle -θ of the rudder surface base 3 relative to the fixed platform 1, the rudder surface 4-1 can always be kept in a horizontal position, which is convenient for later tests under different angle conditions.
[0114] The embodiments of the present invention have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
