【 摘 要 】

This work studied and presented a high-power Hall-effect electric propulsion thruster. The working Xenon gas is heated and ionized by nuclear energy to generate plasma which is injected into the channel. The plasma in the channel is described by two-temperature model consists of ions, electrons and atoms with the electron density of plasma above 1020 m-3. The Lorentz force acting on the plasma makes the flow velocity increase obviously. The operating power of the thruster is about 20 kW. The mass flow rate of xenon is set at 1.56 g/s.
