摘要: A two-fluid model of the unmagnetized, collisionless far region expansion plasma plume for gridded ion thrusters and Hall effect is presented. The integrated into two semi-analytical solutions valid in hypersonic case. These are discussed compared against results from (exact) method characteristics; relative errors density velocity increase slowly axially radially order 10−2–10−3 cases studied. density, flux ambipolar electric field investigated. sensitivity analysis problem parameters initial conditions carried out to characterize divergence angle range interest space propulsion. qualitative discussion physics secondary also provided.
