非制导炸弹投掷的攻击航迹规划研究

战斗机投掷非制导炸弹,需要预先对攻击航迹做出合理规划,以提高作战效能和生存能力。为此,提出一种战斗机的攻击航迹规划方法。首先建立战斗机运动模型,生成基本战术动作模型库,并将动作组合合成为基本航迹;然后,构建各阶段动作参数的开闭环控制模型,对战术动作进行微观控制,并依据飞行员经验确定参数变化的约束范围;最后,基于非制导炸弹的基本性能和战术运用方式,限定战机的投掷参数,进而完成航迹规划。对机动跃升加俯冲攻击战术进行仿真分析和演示验证。结果表明:所规划航迹满足攻击条件,运动参数符合飞行要求,验证方法可行有效。

Attack Path Planning for Throwing Unguided Bomb

In order to ensure that the trajectory parameters of fighter meet the throwing conditions of unguided bomb, an attack path planning method of fighter is proposed. In this method, a fighter movement model is first established, and a basic tactical action model library is generated, and the action combinations are combined into basic trajectories; then, an open-closed-loop control model of the action parameters in each stage is constructed to microscopically control the tactical actions, and in light of pilot"s experience the constraint range of the parameter change is determined. Finally, based on the basic performance of unguided bombs and the tactical application methods, the throwing parameters of fighter are limited, and the trajectory planning is completed. The simulation result for the mobile jump and dive attack tactics shows that the planned track satisfies the attack conditions and the movement parameters meet the flight requirements, thus verifying the feasibility and effectiveness of the method.
