Rotary multi-pole moment field electromagnetic propeller

Abstract

The invention discloses a rotary multi-pole moment field electromagnetic propeller. The propeller mainly comprises a magnetic field coil, a projectile armature, a power supply circuit, a projectile location detection sensor and a synchronous accurate control chip, wherein the magnetic field coil adopts a multi-pole moment coil assembly, and the hierarchically arranged multi-pole moment coil assembly extends along the moving direction of the projectile armature; a flight duct is arranged between the multi-pole moment coil assembly and the projectile armature; and each coil in the multi-pole moment coil assembly is connected with the power supply circuit so as to acquire discharge pulse current. The rotary multi-pole moment field electromagnetic propeller can generate stronger axial electromagnetic accelerated thrust on the projectile armature, has the advantages of large electromagnetic accelerated force, large transmitted projectile mass, high outlet speed, balanced rotary motion, stable suspension and high efficiency and environmental friendliness, can be widely applied in the fields of locomotive thrust, rocket assist, electromagnetic forming, rotary excavation machinery and the like, and particularly in the technology of vacuum pipeline transporation.

Description

technical field [0001] The invention belongs to the technical field of electromagnetic emission, and in particular relates to an electromagnetic propulsion device based on a rotating multipole moment magnetic field configuration. Background technique [0002] Electromagnetic launch includes electromagnetic propulsion and electromagnetic ejection. It refers to a device that uses electromagnetic force to push a projectile to a certain speed. Since it was originally used as a military weapon, it is also called an electromagnetic gun. Conventional electromagnetic propulsion can be divided into two categories: one is rail type (rail gun), and the other is coil type (coil gun, reconnection gun). [0003] At present, conventional electromagnetic thrusters have some principle defects or face certain technical difficulties. The rail-type electromagnetic thruster has a simple structure. It uses the strong magnetic field generated by two parallel high-current rails to accelerate the c...
