While the experimental side force distribution over a slender body with a blunt ogive nose is basically consistent with the curve of the analogy predicted, and the characteristic points and half cycle of the experimental curve are basically constant with the roll angle changing 360°. But the local maximums in the curve are not the results as the analogy predicted, which is an important flow feature of 3-D slender body than that of 2-D cylinder.

而钝头拱形细长体在大迎角下的截面侧向力分布与脉冲起动横流比拟方法预测的侧向力曲线的形状是基本相同的，而且随着滚转角旋转360°，截面侧向力分布曲线的特征点和半周期基本保持不变，即它们都基本上不受滚转角变化的影响；但是截面侧向力分布曲线极值点形成的原因却是不同的，这是细长体绕流区别于二维圆柱绕流的一个重要特性。
