Variable cross-section channel structure of low-power cusped magnetic field plasma thruster
InactiveCN105736272ALower heat transfer coefficientGuaranteed effective constraintsMachines/enginesUsing plasmaIonizationAtomic density
The invention relates to a variable cross-section channel structure of a low-power cusp magnetic field plasma thruster, which relates to the field of cusp magnetic field plasma thrusters. The present invention aims to solve the problem that under the low power working condition of the existing tangential magnetic field plasma thruster, the insufficient ionization leads to performance degradation when the current density is low, and the performance degradation is also caused by the intensified interaction between the plasma and the wall surface when the current density is high. The problem. The channel is constructed by a ceramic channel and a permanent magnet. The ceramic channel is a one-piece structure, which is divided into two sections: the upstream part of the channel and the downstream part of the channel. The channel structure gradually expands from the upstream part of the channel to the downstream part of the channel. The outer wall of the ceramic channel is used for To achieve clearance fit with the inner wall of the permanent magnet. This structure increases the atomic density and ionization rate in the upstream ionization area, and at the same time reduces the interaction with the channel wall during the accelerated ejection of ions generated by ionization, prolonging the life of the thruster. It is used in the low power working condition of the tangent magnetic field plasma thruster.
