On Controlling the Rotating Speed of the Rotor in an Annular Generator for a Fuze

环形发电机作为引信电源不仅可提高引信的安全性和可靠性,而且还可为引信解除保险提供独立的第二环境激励源。通过对环形发电机工作原理及结构的分析,给出了一种转子转速控制机构的实现途径和仿真分析、试验结果。仿真分析和试验结果表明,该机构可以实现在弹丸低速飞行时可靠工作、在弹丸高速飞行时可调节与控制自身转速的功能。

By using an annular generator as the power supply for a fuze, not only the safety and reliability of the fuze is improved, but also an independent second signal for starting the arming is provided. In this paper, an achievable approach is given for controlling the rotating speed of the rotor in the annular generator. CFD simulations and field tests are performed for the controlling device. Results show that the device runs reliably at lower speed, and can adjust or control its rotating speed by itself at higher speed.
