固定翼二维弹道修正引信升力翼面位置的影响

The Influence of Fixed-wing Two-dimensional Trajectory Correction Fuze Lift Airfoil Mounting Position

固定翼二维弹道修正引信研究需要了解翼面之间的气动干扰。鉴于查不到相关文献,采用流场计算中广泛使用的数值模拟方法,计算引信及翼面的气动参数和修正弹的流场分布。计算结果表明,在固定翼二维弹道修正引信翼面尺寸和安装角度不变的前提下,随着升力翼面安装位置的前移,固定翼二维弹道修正引信的导转力矩、导转翼面的阻力和导转力矩以及升力翼面的阻力和升力均有所增加,而对导转翼面升力的影响较小;在跨音速时,引信及翼面的气动参数均变化较大。

The studies of two-dimensional trajectory correction fuze with fixed-wing were needed to understand the relation between the aerodynamic interference of airfoil.In view of the lack of relevant literatures,the aerodynamic parameters of the fuze and airfoil and the flow field distribution of correction shell were calculated by using the simulation method of the effective value in the flow field calculation.The calculation results showed that under the condition of same size and installation Angle in two-dimensional trajectory correction fuze airfoil,with the installation position of lift airfoil forward,it was increased to the angular moment of two-dimensional trajectory correction fuze with fixed-wing,the resistance and angular moment of roll airfoil and the resistance and lift of lift airfoil.But it had little influence on the lift of roll airfoil.In transonic,fuze and airfoil aerodynamic parameters changed greatly.
