滑板－土壤间充气层面积的试验研究

Test Study on the Area Membrane Introduced Between Slide and Soil

充气层面积直接影响到气幕减阻的效果。在试验的基础上，观测到了充气层的形状及形成过程，揭示了充气层面积与流量、接地比压、充气孔数、减阻率的关系，并作了进一步探讨，从而提出了提高减阻率的合理途径。

The area of air membrane has a direct influnce on the efficiency of resistance reduction by air curtain. Through the experiments conducted by the authors, the shape and the forming process of the air membrane have been observed. Based on the observation, the relationships of the air membrane area to the air flow, the ground contact pressure, the number of the inlet holes on the slide and the resistance reduction rate are revealed and further discussed. Some suitable approaches are proposed to increase the resistance reduction rate.
