▎ 摘　　要

NOVELTY - Pulsed E-field propulsion system comprises at least one capacitor stack comprising at least one capacitance elements having surface geometries of either flat parallel planes, right circular cylindrical sections, or spiroidal ribbons, at least one pulse coil, electromagnetic field, at least one energy supply comprising storage batteries, fuel cells, solar panels, fuel-oxidizer electric generators, radioisotopic thermal generators, and/or nuclear electric generator systems, at least one pulse control circuit, at least one charge control circuit, where a unique apparatus is constructed for producing net unidirectional Lorentz Force on the system, the Force results from directed high time-rate-of-change electric fields generated by pulse coils acting on electric charges stored in capacitor stacks, and further where electromagnetic reaction momentum is carried away by Poynting vector fields, thus producing thrust on the system without expelling propellant. USE - The pulsed E-field propulsion system is useful in spacecraft. ADVANTAGE - The pulsed E-field propulsion system: produces thrust levels without expelling propellant or requiring large electric power sources, thus eliminating need for tanks of propellant; has capability of reuse without refueling, as well as long duration continuous thrusting; is superior to existing high specific impulse fuel oxidizer engines and electric ion propellant thrusters; and utilizes lead magnesium niobate with strontium titanate and/or barium titanate which exhibits high dielectric constant, low dielectric loss, high breakdown strength, low field-induced strain, high electrical resistivity and exceptionally high energy storage capacity.
