针对目前滑翔弹射程短的缺点,提出一种改进的“钻石背”弹翼。通过增大后掠翼的后掠角、前掠翼的前掠角和展弦比来改进钻石背弹翼,分析计算在飞行攻角为0°~8℃的使用条件下不同飞行马赫数时的气动特性。在逆风飞行条件下计算飞行弹道,结果表明在12000m高度,270m/s水平速度投弹的条件下,射程达到110km以上。通过对翼张机构的设计,在原理上说明了菱形弹翼张开机构的可行性。

Aiming at the defect of short flight distance of glide bomb, an improved diamond wing was proposed. The improved method is to enlarge large aspect ratio and sweep forward wing angle of the sweep forward wing. And aerodynamic characters were analyzed at different Ma and 0°~8° of attack angle. The ballistic trajectory was calculated under the windless and dead wind. The result show flight distance exceeds 113km at height 12000m and level velocity 270m/s. With the improvement of the wing spread mechanism, the feasibility of the improved wing is theoretically explained.
