本文总结了后掠薄翼前缘附着流发生的现有实验数据。结果表明，从分离流到附着流的变化发生在垂直于前缘的马赫数为亚音速时，并且这种变化所需的马赫数随迎角的增加而增加。它还表明，马赫数和冲角的条件，保持在边界上划分两种类型的流动的机翼与直边也适用于局部点的“哥特式”机翼的前缘。本文简要讨论了这一结果对一般曲边机翼绕流的影响。
Existing experimental data on the occurrence of attached flow around the leading edges of swept plane thin wings is summarised. It is shown that the change from separated to attached flow occurs while the Mach number normal to the leading edge is subsonic and that the Mach number required for the change increases with incidence. It is also shown that the Mach number and incidence conditions which hold on the boundaries dividing the two types of flow on wings with straight edges also apply locally at points on the leading edges of “Gothic” wings. The implications of this result on the flow over general curved-edge wings is briefly discussed.
