Test were made on three circular-arc-fuselage and nine unswept-vertical-tail models in order to investigate interference effects between fuselages and vertical tails in sideslip. The mutual interference effects, and thus the effectiveness of the vertical tail in producing directional stability, appear to be mainly dependent upon the ratio of the vertical-tail span to the fuselage diameter at the position of the vertical-tail aspect ratio and to be relatively independent of the fuselage fineness ratio.
