Abstract: Aiming at the problem of the exit speed of the electromagnetic launching device, based on the two-stage magnetoresistive transmitter, the combined use of TypeⅠ and TypeⅡpulse forming network (PFN) modules was used to optimize the overall design of the electromagnetic launch system. The mutual inductance between the transmitting coils is used to achieve the zero-crossing shutdown of the discharge circuit during the launch process, the deceleration effect during launch was weakened, and the feasibility of the design was verified through experiments. On the basis of this design, different timing triggers were optimized, which significantly improved the export speed of projectile.
