    摘要: A Hall effect thruster for propelling spacecraft and satellites includes at least two acceleration channels, each of the channels has a closed end and an open end, and a plurality of flux guides adjacent each of the channels. The plurality of flux guides includes an innermost flux guide, an outermost flux guide, and at least one intermediate flux guide. Each intermediate flux guide helps provide a magnetic field to each of two adjacent acceleration channels.

    摘要: A solid divert and attitude control system for use on a kill vehicle or missile that includes a solid propellant gas generator, a control valve for modulating the effective exit area of the solid propellant gas generator, and a controller for calculating the integral of the burn rate of the solid propellant and for controlling operation of the control valve in response to the calculation of the integral of the burn rate of the solid propellant. The solid propellant gas generator has a solid propellant with a non-constant burn area and a grain profile which includes a first boost phase grain, an intermediate sustain phase grain, and a second boost phase. The controller controls operation of the control valve during a coast phase of the mission so that the second boost phase grain does not ignite until the beginning of the terminal phase of the mission.
