A Fuze Ignition Energy Accurate Control Method Considering Thermal Battery Activation Time Spread
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 op-eration,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 distri-bution 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 am-munition experiment.
