The research of fuze-ranging for the turns count projectile

According to the property of geomagnetic field and the basic principle of electromagnetic induction, the mathematical model is established in this paper. Instead of using magnetic core, a new method of wrap the induction winding is brought out so as to resolve some technique problem. With the help of storage testing, via experimentation of lathe circumrotate, hand rotating centrifuge circumrotating and firing retracting, curve of inducting electromotive force produced by shell rotation and the geomagnetic flux in different rotating speed, different zone and different direction through the winding are obtained, and the feasibility of technique of realizing fuze-ranging during projectile flight revolution is validated.
