摘　　要：通过在细长体顶点处设置扰动块的方式使细长体的绕流具有确定性,在此基础上研究了机翼对细长体头部侧向力特性的影响。通过实验发现,测压截面越靠近机翼顶点,受机翼的影响越大。在50°迎角以下,后掠翼对细长体头部侧向力特性的影响很小。在60°迎角时,后掠翼对细长体头部的侧向力特性影响较大,此时单独细长体的侧向力特性实验结果已不能直接应用于后掠翼身组合体了。In the experimental study of this paper, crossflow around a slender became confirmable with manual perturbation on tip of slender. And the study on influence of aerodynamic configurations on side force of slender has been carried out on this base. It＇ s been found that the measurement section was nearer to the wing, the effect of wing was greater. At angles of attack less than 50°, the effect of sweep wing on side force of forebody was little . At angle of attack a = 60°, the sweep wing had significant effect on the side force of forebody, thus the experimental results of a single slender can not be used in the sweep-wing-body combination.
