本文报道了从圆锥到三角翼的各种圆锥体上出现非对称流动的理论和实验结果。发现流动中的对称性破缺可以很好地用理论预测圆锥体的对称性破缺，并且也支持对较薄物体的不对称性的较高阻力的预测，尽管没有达到理论所指示的程度。本文给出了锥形体上带有自由涡的非对称锥形流和非锥形流的发展数据，包括涡破裂的影响。
Theoretical and experimental results for the appearance of asymmetric flows on conical bodies varying from circular cones to delta wings are reported. Symmetry breaking in the flow is found to be well predicted by tbeory for circular cones, and the predicted higher resistance to asymmetry for thinner bodies is also supported, although not to the extent indicated by theory. Data are presented on the development of conical asymmetric, and nonconical flows with free vortices on conical bodies, including the effects of vortex breakdown.
