  • Patent number: 9359091
    Abstract: An artificial gravity system and method for a spacecraft including a least one pair of rotatable stages wherein each stage is capable of rotating about at least one structural support in the spacecraft and wherein the rotatable stages in each pair of rotatable stages counter-rotate one another wherein each stage is capable of accommodating a plurality of occupants. The stages may be circular and deployable. The system may also include dynamic balance equipment in each stage consisting of a fluid redistribution design utilizing fluid pumping systems, storage- and reserve-volume tank pairs to redistribute fluid throughout each stage for optimal mass balance, stage- and spacecraft-mounted laser-tracking equipment for redundant speed measurement, drive assembly and a brake motor and wheel assembly, foldable structural support arms capable of reducing the radial space of each stage during takeoff, and an inertial measurement unit capable of detecting overall vehicle rotational rates.
