Method and application analysis of remote magnetic controlling for space target
Compared with the traditional spacecraft control methods,inter-satellite electromagnetic force/torque has the advantages of no propellant consumption,no plume pollution,and strong controllability.Therefore,it has received extensive attention in the research of rendezvous and docking,spacecraft formation and cluster,as well as the de-spin of failed satellites.However,the magnitude of electromagnetic force/torque is inversely proportional to the power 3-4 of the distance,as a result,the effective space of electromagnetic force/torque is limited.The plasma ring with the spheromak configuration produced by the magnetized coaxial gun has high transmit speed(about 1 000 km/s),high electron density(about 1016 cm-3),high energy density(about 1 MJ/m2),and the frozen strong toroid and polar magnetic fields are generated by the discharge current of plasma ring as well.Inaddition,the generation and delivery environment of the plasma rings conforms with the vacuum environment of space.Based on the new magnetic control method in which the magnetic coaxial gun produced the plasma ring with spheromark configuration,and then delivers the magnetic field carried by the plasma ring to a distance,this paper studies the magnetic controllability and the application potential of the plasma rings in de-spinning/reclaiming of the space target by controlling the coaxial gun to create the desired plasma rings,and verifies the exactness of the conclusion by simulation examples.
