R&D of a Foldable Obstacle-Striding Electromagnetic Coilgun

Abstract:

Electromagnetic coilgun and obstacle-striding mechanism are creatively integrated into the foldable obstacle-striding electromagnetic coilgun. According to the theorem of kinetic energy, permanent magnet NdFeB is used as a collisional armature to accelerate the projectile through a central collision. Meanwhile, structures such as shaft in shaft mechanism are designed. Both of the late-model mechanisms make the physical overall structure simple, compacted, and better capable of obstacle striding and operating performance. The testing results and operating performance of this late-model foldable obstacle-striding electromagnetic coilgun appear to be excellent through observing and analysing the results of experiments. It can successfully cross stairs, steps and other usual obstacles. If the stage and the number of turns of induction coil are increased, with safety protecting device, this equipment will be able to put into practice further in particular fields, for instance, military, anti-terrorism, tall building fire fighting and so on.
