System and method for support and rotation of volume

摘要

There is disclosed a system and method for rotationally controlling a circular structure, such as a dome, from the outer circumference of the dome. The system uses an air driven motor having a circular fixed section and a movable section. The movable section is attached to the rim of the dome and is supported by pressurized air over the fixed section. Air, or other fluid, is used to drive the movable section, and hence the dome, around the circle. The dome speed is controlled by air pressure and the position of the dome is monitored.
