A Counterrotator for Human Centrifuge Application

Abstract

A new man-rated vestibular research device, identified as the Counterrotator (CORO), was developed to investigate man's response to the dynamic linear acceleration environment afforded by counterrotation aboard a centrifuge. The device proper is a small Earth-vertical rotator which utilizes a DC torque motor operated as a closed-loop position servo to turn a seated subject about his z head axis. When installed aboard the radial arm of the Coriolis Acceleration Platform (CAP), a centrifuge-like rotator, the CORO drive system will track the angular motions of CAP over the 0- to 100-deg/sec velocity range at angular accelerations extending to 15 deg/sq sec. The device is rated to achieve this 1:1 counterrotation capability in low-level, variable magnitude, centripetal acceleration fields extending from 0 to 1.75 g nominal.
