Abstract
This invention provides a mechanism to create an artificial gravitational environment in a toroidal space station in which gravity may vary from zero, of advantage during repairs, manufacturing and research activities, and docking maneuvers, to values greater than one g for preparing astronauts for missions to other planets, or for other purposes. The mechanism couples the rotation of a high density cylinder in the center of the hub to that of the torus through gears such that the total angular momentum of the station is zero, allowing maneuvering of the station to be less complicated since gyroscopic effects are eliminated, and the level of gravity in the torus to be varied without the use of external thrusters. Gears are driven by motors attached to the hubs, providing redundancy for maintenance and emergency operations, with power provided by solar cells, a nuclear power plant, or other means.
