During the launch and flight process, the aircraft is in a horizontal posture, a vertical posture, or a transition between various postures when flipping in the air. It is necessary to test the working conditions of various instruments inside the aircraft on the ground. In order to ensure that the data is closer to the actual value, the aircraft should be adjusted to different postures for testing. When testing and testing in different postures, due to the change of the position of the bearing interface, different testing platforms should be made to meet various tests and tests. However, the spacecraft has large dimensions and heavy weight. When testing and testing in different postures, the aircraft needs to be hoisted back and forth between various testing platforms.
