Problems solved by technology
However, compared with hovercraft, air-cushion wing-in-ground effect vehicles have high speed, obvious aerodynamic effect, and more complex action principles. The design method of using hovercraft often cannot accurately simulate the working conditions of air-cushion wing-in-ground effect vehicles sliding on the water surface
[0003] At present, there is no practical test method for the model tank of the air-cushion wing-in-ground effect vehicle

Embodiment Construction
[0018] Below in conjunction with accompanying drawing, the present invention is further described:
[0019] Such as figure 1 , figure 2 Shown, test procedure of the present invention is as follows:
[0020] a) Installation of WIG model test:
[0021] The wing-in-ground effect ship model 1 is connected to the sliding device composed of the center of gravity strut 7, the trolley 5 and the heave rod 6, and is installed on the airworthiness instrument 8 below the hydrodynamic high-speed test trailer system 12, the sliding The device ensures that the wing-in-ground effect ship model can move freely up and down within a certain range and along the airworthiness instrument 8, and the active connection point between the center of gravity strut 7 and the wing-in-ground effect ship model 1 should take the position of the center of gravity of the wing-in-ground effect ship model 1 point, and connected by hinges, the WIG model 1 can freely pitch and rotate around the center of gravity...

The invention belongs to the technical field of ground-effect wing boats, and relates to an air-cushion type ground-effect wing ship model water pool dragging test method. According to the invention,the research of the air cushion type ground-effect wing ship model water pool dragging test method is carried out, and the data related to the rapidity and the stability of an air cushion type ground-effect wing ship are accurately tested, and the rapidity and the stability of the air cushion type ground-effect wing ship real-time ship can be accurately forecasted, and the design of the air cushion type ground effect wing ship can be better verified. The method is practical and feasible, and is simple to operate, reliable in test result and wide in application range.
Description
technical field [0001] The invention belongs to the technical field of WIG boats and relates to an air cushion type WIG boat model pool dragging test method. Background technique [0002] The air-cushion wing-in-ground effect ship usually takes off and lands on the water surface, and its rapidity and stability when gliding on the water surface directly affect the safety, comfort and range of use of the wing-in-ground effect ship in use. The rapidity and stability of WIG craft mainly refer to the design method of hovercraft at present. However, compared with hovercraft, air-cushion wing-in-ground effect has high speed, obvious aerodynamic effect, and more complex action principle. The design method using hovercraft often cannot accurately simulate the working conditions of air-cushion wing-in-ground effect sliding on the water surface. [0003] At present, there is no practical test method for the model water tank of the air-cushion type wing-in-ground effect vehicle. There...
