Plasma generation device and method based on multi-stage magnetic field and multi-section spray pipe

Abstract

The invention relates to a plasma acceleration propulsion device, in particular to a plasma generation device and method based on a multi-stage magnetic field and a multi-section spray pipe. The technical problem that the specific impulse and thrust are not ideal due to the fact that a plasma generating device with a single-section spray pipe is not favorable for optimizing the configuration of a magnetic field and the trajectory of plasma jet is difficult to control is solved. The device comprises a working medium supply and distribution unit and a plasma generation acceleration unit, wherein the working medium supply and distribution unit comprises a working medium distributor, a second insulator, a transition electrode and a third insulator which are coaxially arranged from inside to outside; the plasma generation acceleration unit comprises n sections of spray pipes, n-1 sections of first insulators, accelerator electric field power supplies corresponding to the spray pipes, electromagnetic coils corresponding to the spray pipes and electromagnetic field power supplies corresponding to the electromagnetic coils; and the n sections of spray pipes and the n-1 sections of first insulators form a spray pipe assembly. The invention further provides a plasma generation method based on the multi-stage magnetic field and the multi-section spray pipe.
