摘要
随着弹药威力的增加以及近距离作战的需求,迫切需要引信在弹药发射后由安全状态向待发状态快速转变,因此需要优化引信发火能量控制策略。针对引信热电池工作初期电能输出与带负载能力不足的问题,建立引信发火电能控制模型并展开分析,通过增加发火电容充电延时,并进行延时参数优化,从发火能量控制角度来满足弹药在不同作战条件下安全距离及最小作战距离的双重约束要求。发射前根据弹丸初速、热电池上电时间散布特性、引信电路参数等条件解算充电延时时间参数值,利用武器平台与弹丸的信息交联,实时调整引信充电延时以实现引信发火电路安全与起爆条件精准控制。仿真分析了充电延时与电路参数、安全距离以及最小作战距离的关系,并通过试验验证了该方法的有效性。
With the increase of the power of ammunition and the demand of close combat,it is urgent to change the fuze from the safety state to the arming state,and optimize the control strategy of fuze firing energy.Aiming at the problem of insufficient power output and load capacity of the fuze thermal battery at the initial stage of operation,a fuze ignition power control model was established and analyzed.By increasing the ignition capacitor charging delay and optimizing the delay parameters,the dual constraint requirements of the safe distance and the minimum combat distance of ammunition under different combat conditions were fulfilled.Before launching,the charging delay time parameter value was calculated according to the projectile initial velocity and the time distribution characteristics of the fuze thermal battery and the parameters of the fuze circuit.By using the information of the weapon platform and the projectile,the charging delay of the fuze was adjusted in real time to realize the safety of the fuze firing circuit and the accurate control of the detonation conditions.A mathematical model was established and the relationship between charging delay and circuit parameters,safety distance and minimum combat distance was simulated and analyzed.The effectiveness of the method was verified by the tank gun ammunition experiment.
