Background
A ground effect test of an aircraft is carried out in a low-speed wind tunnel, a liftable floor is required to be erected at a wind tunnel test section, and the height change from the ground in the taking-off and landing process of the aircraft is simulated. Meanwhile, the airplane model needs to be supported and driven through a tail support (small in damage to the appearance of the airplane structure and small in pneumatic interference), and pitching motion in a large range is achieved. Because the rotating shaft of the pitching motion of the airplane model is usually positioned near the wing, the up-and-down swinging amplitude of the end, far away from the airplane model, of the tail boom support often exceeds the distance between the rotating center of the airplane model and the floor. Therefore, an opening is needed on the floor table top to reserve a movement space for the tail boom support rod. Particularly, under the working condition of a zero-height ground effect test, the height of the airplane model from the floor is very small (less than or equal to 10 mm), the geometrical interference stroke of the tail support supporting rod and the floor is large in the pitching and raising process of the airplane model, the moving speed of the interference point is high, and the interference point is strongly changed in a nonlinear mode. In order to meet all ground effect test working conditions, the floor opening is often large, and even most of the projection area below the machine body is occupied. The air flow moves up and down in the open area of the floor, which will seriously affect the reality of the ground effect simulation. Therefore, the floor notch must be sealed, the moving direction of the tail boom support rod in the notch can be freely and quickly moved, and the area of the vertically through notch is reduced as much as possible.
