摘要

针对变前掠翼(VFSW)无尾布局的横航向操纵,设计了开裂式方向舵(SR)操纵面,采用Navier-Stokes控制方程的有限体积离散方法以及剪切应力输运(SST)湍流模型,计算了变前掠翼中平直翼和典型的前掠翼布局开裂式方向舵的操纵性能,并对其操纵效率进行了比较,分析了其流场形态。计算结果表明:右侧开裂式方向舵打开后,平直翼时迎角对偏航力矩的影响较小,而舵偏量对偏航影响显著,利于偏航;前掠翼的偏航力矩随迎角的增加有所波动,但在小迎角时较为稳定,偏航作用随舵偏量增加而增强;右侧滑对滚转作用强于左侧滑,偏航作用低于左侧滑。经比较,平直翼的偏航作用明显强于前掠翼,平直翼和前掠翼的滚转和偏航作用均具有耦合性,但平直翼的耦合效应弱于前掠翼。

Abstract

For the lateral and directional control of variable forward swept wing (VFSW) tailless configuration, a split rudder (SR) is designed in this paper. The disperse method of Navier-Stokes control equations with finite volume and shear stress transport (SST) turbulence model are employed to calculate the SR control characteristics of the orthogonal wing and forward swept wing in VFSW the control efficiency of SR is compared, and the flow field of SR is numerically analyzed. The computational results show that the case when the right SR actuates the angle of attack in the orthogonal wing has less effect on the yawing moment, while the rotary angle of SR has a remarkable impact on the yawing moment, which is propitious to yaw. In the forward swept wing configuration, the yawing moment tends to fluctuate with the increase of the angle of attack, but it appears steady in small angles of attack. The yawing function strengthens with the increase of the rotary angle. The right sideslip is stronger than left sideslip, but the opposite is true in yawing function. Comparatively, in the aspect of yawing, the orthogonal wing is better than the forward swept wing. The rolling and yawing are all coupled in both the orthogonal wing and forward swept wing configurations, but the coupling effect of the orthogonal wing is less than the forward swept wing.

Key words： variable forward swept wing; split rudder; numerical simulation; control characteristic; flow field
