A Light Armored Active Protection System Rocket Fuze Program

Vehicles play an important part in modern wars. Many countries put emphasis on improving defense ability of vehicles. Active protection system is one kind of vehicle protect system that is reliable. It can launch intercept ammunition to damage incoming projectile. Fuze played a very important role in this course. So the performance of the fuze will directly affect protect results.This article dissertated a kind of rocket fuze that is designed for active protection system. To meet the performance requirements, the fuze can achieve accurate timing, multi-point detonation and directional detonation. Under The direction of the projectile axis, there are four detonation trains in the circle. Use level rotator as detonation interrupter. It can interrupt or align four detonation trains. Use zigzag slot arming device and shear arming device. The fuze got power and data through inductive setting. With the help of single chip processor, the fuze can time accurately. According to the inductive setting data, when time is up single chip processor give signal to detonate one or two detonation trains. In this way, the fuze can detonate in eight directions.Rationality of the design was validated in theory by using the design and calculation of the fuze structure. Dynamic characteristic of the structure was acquired from the dynamic simulation conducted based on ADAMS. Then two arming devices experimentations are followed to validate that they can guarantee the logistic handling safety. Through doing detonator safety test to validate that it can work reliably. In the end, doing detonation experimentation on detonation circuit to prove that it can detonate reliably.It is a kind of electronic time fuze that can achieve four points eight directions detonation control. The fuze can be used in rocket of active protection system for combat car.
