在低速风洞中，以跑带为地平面，对地效飞行器模型“Marine Slider：μ sky”进行了六分量测量。“μ sky-1”是一种实验性的海洋飞行器，带有简单的冲压翼。它的翼段是一个高弯度的薄段，以提高其在地面效应的性能。试验模型的机翼是展弦比为0.625的方形机翼，翼尖板从两个翼尖向下延伸。计算结果表明，该机翼的地面效应是显著的。阻力减小得不够。其原因是在船体底部与地面之间的狭窄间隙中存在强烈的剪切流。剪切流增加了阻力。
Six-component measurements of a model of a wing-in-ground effect craft (WIG) “Marine Slider: μ sky” were conducted in a low speed wind tunnel using a running belt as the ground plane. The “μ sky-1” was an experimental marine craft with a simple ram wing. Its wing section was a high cambered thin section to improve its performance in the ground effect. The wing of the test model was a square wing of the aspect ratio 0.625 with tip plates extending downward from both tips. Results obtained show that the ground effect is remarkable for this wing. The drag was reduced not enough. The reason was that there was a strong shear flow in a narrow clearance between the hull bottom and the ground surface. The shear flow increased the drag.
