为了研究具有良好隐身特性的V形尾翼的气动设计准则，通过风洞实验，探讨了机翼不同上反角和副翼位置对V形尾翼的飞机全机气动特性的影响.比较了两种V形尾翼与常规尾翼的纵、横向气动特性.研究结果表明，机翼上反引起全机偏航力矩曲线呈非线性；靠近翼根的副翼偏转引起副翼偏航效率与其滚转效率同样量级.因此，设法使尾翼避开不对称的下洗流场的影响是V形尾翼设计的一项重要准则.

Experimental investigation of the aerodynamic design of the vee tail featuring low RCS has been carried out. The effects of the wing dihedral angles, and aileron positions on the aerodynamic characteristics of the complete aircraft with vee tail are studied. Aircraft models with two types of vee tail and two conventional tails have been tested and the longitudinal/lateral performances compared. The results show that off-shipping moment curves are caused nonlinear by the wing with dihedral, and that the same order of off-shipping efficiency of aileron as that of its rolling efficiency is caused by the deflection of inboard aileron. Therefore, it is an important criterion that vee tail should avoid the effect of the asymmetric downwash in aerodynamic design.
