Coaxial coil electromagnetism propulsion system

Abstract

The invention discloses a coaxial coil electromagnetism propulsion system which comprises a driving coil, a projectile armature, a power supply device, a controllable switch, a projectile armature position detecting sensor and a synchronization accuracy control chip. A diode D2 is connected in series to a winding type coil 10 of the projectile armature. Negative force influence caused by armature capturing effect can be completely removed through the armature. For both of a solid armature and a coil type armature, vortexes sensed on the armatures during an electromagnetism propulsion process can flow in double directions, and the armatures can move in acceleration mode under electromagnetism repelling force and move in a deceleration mode under electromagnetism attracting force. Deceleration influence caused by the armature capturing effect is avoided. According to the propulsion feature, the coil type armature is improved, the diode is connected in series to the coil, vortex reverse flow is inhibited, so that only forward-direction acceleration force is exerted on the armature, backward-direction deceleration force is removed, and propulsion performance is improved.

[0003] Electromagnetic propulsion technology is a new propulsion method that has emerged in recent decades and has broad application prospects. However, due to some theoretical defects and limitations of some technical problems, this technology is still in the experimental research stage

The electromagnetic railgun is a relatively mature propulsion technology at present. It uses a large current to flow through two parallel guide rails to generate a strong magnetic field to push the armature in contact with the two guide rails. The guide rail and the armature have to bear a huge heat flow impact during the launch process, which is easy to cause serious ablation and surface peeling, and the outlet of the guide rail is prone to arc phenomenon, which seriously affects the service life of the electromagnetic railgun, the exit speed of the projectile and the launch efficiency. improve

Coaxial coil guns and reconnection guns are collectively referred to as coil guns, which have the advantages of large propulsion mass, non-contact ablation, and high emission efficiency. However, due to the limitations of pulse power supply technology, synchronous control technology and switching devices, it is difficult to pass the armature Multiple stages of precisely controlled firing to very high velocities, limiting the usefulness of coilguns
