The slow rotation room facility is 22 feet in diameter, fully enclosed, with a ceiling height of between 7 feet 10 inches at the center of rotation and 7 feet 3 inches at the periphery. It has a net weight in excess of 7 tons. The room has two separate drive systems. The linear induction motor system was designed specifically for our rotation application. It has the capability of developing a constant torque of 2350 foot pounds which can produce a gravitoinertial force in excess of 4g within the room for a 6000 pound payload.
Feedback control ensures a constant room speed while people or objects are moving within the room.
The room can also be sinusoidally oscillated over a wide range of frequencies. The slow rotation room can accommodate a wide variety of test devices with on board power for those requiring either 110 VAC, single phase current or 220 VAC, single or three phase current. The floor of the room is laid out with a 20 inch grid for securing apparatus. NASA's KC-135, 0g test aircraft so that consoles can be interchanged between the test facilities. The floor layout of the room is illustrated in Figures 1 and 2.
