国外利用斜翼方式增大弹药射程的方法

为了达到无需火箭辅助而增大射程，对国外采用弹体斜翼／尾翼的方式增加弹药射程的方案进行了介绍；该设计方案具有智能舵机控制，制导弹药从超音速、音速，到亚音速的整个滑行阶段，均将保持最大升阻比；为了分析超音速与音速滑行阶段内给定的马赫数与攻角时不同斜翼的最佳后掠角状态，利用重叠网格法进行了系统的纳维-斯托克斯方程计算，通过对斜翼的最优配置设计，无需火箭助推便可使弹药达到100n mile的目标射程。

Foreign Research on Extension of Projectile Range Using Oblique-Wing Concept

An innovative projectile design using body-conformal oblique wing/tails with smart-structure （actuator） control has been proposed to achieve an extended range without rocket assistance. This guided projectile would maintain the maximum lift-to-drag ratio throughout its gliding phase, from supersonic, through transonic, to subsonic gliding regimes. Intensive Navier-Stokes computations using the overset-grid approach have been performed to search for the optimal sweepback positions of the oblique wing for the giv-en pairs of Mach numbers and the angles of attack in the supersonic and transonic gliding phases. With such an optimal deployment of the oblique wing, it is feasible for the projectile to achieve the target 100 nm range without rocket assistance.
