Abstract
This application relates to an adjustable support system for full-aircraft modal testing of a small general aviation aircraft, including a suspension wheel, suspension ropes, and lifting rings. One side of the suspension wheel is the suspension rope connection side, and the other side is the lifting ring connection side. The suspension wheel has multiple suspension rope connection joints on the suspension rope connection side and a lifting ring connection joint on the lifting ring connection side, with the lifting ring connection joint located at the center of the suspension wheel. There are thirteen suspension rope connection joints on the suspension wheel, including one central connection joint, six inner layer connection joints, and six outer layer connection joints. There are two suspension wheels: an upper suspension wheel and a lower suspension wheel, with their suspension rope connection sides facing each other, and some or all of the suspension rope connection joints connected by suspension ropes. There are two lifting rings: one ring is connected to the lifting ring connection joint on the upper suspension wheel for connecting an electric hoist; the other ring is connected to the lifting ring connection joint on the lower suspension wheel for connecting the aircraft.
