| 摘 要： | 为解决小口径电子引信设计空间小的难题,结合引信可编程感应装定技术,提出在弹丸发射前进行信息装定的过程中存储感应能量为引信供能。该方法节省了安装电源所需的空间,为小口径弹药的电子引信电源设计提供了一种新的思路。为此建立小口径膛内电磁感应数学模型,并分析非铁磁性金属炮管内电磁场穿透特性。分析得出,外激电源谐振频率只有小于5 kHz,才能保证穿透后的磁场强度为信源磁场强度的80%;随着信源磁场频率的增加,穿透后的磁场强度呈指数规律衰减。实验表明,利用上述理论设计的某小口径感应储能引信原理样机,性能满足引信的技术要求。该结论能够用来指导膛内小口径引信感应装定及感应储能的设计。

| Abstract: | A method of which the stored inductive energy is provided for fuze in the process of information setting before a projectile lauch was proposed in order to solve the problem of small room for designing a small-calibre electronic fuze.This method,which can save the space of extra fuze power,provides a new way to design fuze power.Therefore,a mathematical model of electromagnetic induction in the bore was set up.The characteristics of magnetic field penetrating through the metal gun barrel made of nonferromag... |
