在制导炸弹技术现有水平的基础上,针对一种大反安定翼+固定弹翼+前掠折叠尾翼+后缘舵的气动布局方案进行了优化研究。在减小反安定翼的翼展和弦长基础上,去掉固定弹翼中后部,只保留尾部固定弹翼前部安装折叠弹翼,大大降低了全弹弹翼张开状态的静稳定度,同时减少了大部分尾部固定翼的质量。采用FLUENT6.3计算和仿真结果表明:展开状态时静稳定度在4%~8%之间,收缩状态最小静稳定度大于1%,具有很高的机动能力和过载能力,升阻比与宝石路ⅢGBU-24-A/B的升阻比接近,可以达到宝石路的滑翔能力。

An aerodynamic configuration of counter-balanced wing + fixed wing + forward foldable tail wing + back rudder was optimized based on actual technologies of guided bomb. On the base of reducing wingspan and chord length, mid-back part of fixed wing was removed, and stationary stable degree of spreading state was greatly declined, at the same time, great mass of fixed wing was lessened. The result calculated and simulated with FLUENT 6. 3 software shows that the stationary stable degrees of spreading and shrinking state are respectively 4%~8% and 1%, and has great motion and over-loading ability. Compared with GBU III-24-A/B, the lift-drag ratio of them is almost the same, and it achieves GBU gliding ability.
