基于动态耦合分析的武装直升机火/飞协同机制研究

Research on Fire/Flight Coordination Mechanism of Armed Helicopters Based on Dynamic Coupling Analysis

针对武装直升机使用航炮、火箭弹等非控武器对地面目标瞄准攻击的问题,提出一种基于动态耦合分析方法的火/飞协同机制。根据武装直升机连续计算命中点(continuously computed impact point,CCIP)攻击原理,通过攻击误差分析建立瞄准误差矢量方程组。运用动态耦合分析机理建立火/飞变量间的动态耦合矩阵,并对其进行标准化、归一化处理,得到其耦合关系,以此为依据采用构造罚函数方法和共轭梯度法对瞄准矢量方程组进行解算,给出基于动态耦合分析的火/飞协同机制。仿真结果验证了该机制的可行性及有效性,为解决武装直升机空对地瞄准攻击问题提供有价值的参考。

Aiming at the problem that armed helicopters use uncontrolled weapons such as cannons and rockets to aim and attack ground targets,a fire/flight coordination mechanism based on dynamic coupling analysis method is proposed.According to the CCIP(continuously computed impact point)air-to-ground attack principle of armed helicopters,the attack error analysis is used to establish the aiming error vector equations.The dynamic coupling analysis mechanism is used to establish the dynamic coupling matrixes between the fire and flight signals and to standardize and normalize them to obtain the coupling relationship,based on this,aiming vector equations are solved by the construction of penalty function method and the conjugate gradient method,and the fire/flight coordination mechanism based on the dynamic coupling analysis is proposed.The feasibility and effectiveness of the mechanism are verified by simulation examples,which provides a valuable reference in solving the problem of armed helicopters to make air-to-ground aiming and attacking of targets.
