Abstract
A vehicle propulsion system comprises a propellant source, a microwave energy source; an ionizer, a heater, and a propellant accelerator. The ionizer is configured for receiving propellant and for also receiving microwave energy from the microwave energy source so as to produce ionized propellant. The heater comprises a heater shell that defines a plasma heating cavity and is configured for receiving the ionized propellant from the ionizer. The heater shell is configured to transmit microwave energy received from the microwave energy source to the ionized propellant in the plasma heating cavity and to thereby facilitate absorption of microwave energy by the ionized propellant to produce heated ionized propellant. The propellant accelerator is configured for receiving the heated ionized propellant from the heater, accelerating the heated ionized propellant to produce accelerated propellant, and expelling the accelerated propellant in a desired direction to impose a reaction force (i.e., thrust) upon the vehicle.
