Abstract : The report presents a brief description of the Coriolis Acceleration Platform, a new combined linear and angular motion-producing vestibular research device developed to study the biological effects of aerospace acceleration environments. The primary element of the device is a 20-ft diameter capsule equipped with various life-support equipments to study the long-term effects of continuous rotation. A low rpm, direct-coupled, DC torque motor operated in a closed-loop, velocity mode, power servomechanism configuration rotates the device in either direction at angular velocities extending to 200 deg/sec at accelerations ranging to 15 deg/sq sec. A second drive system can be programmed to produce time-varying rectilinear translations of a single subject along a track structure fixed to the capsule where this form of motion can occur singly, or in combination with rotation of the entire device. Peak ratings of the linear drive system include a radial displacement of plus or minus 20 ft, a linear velocity of plus or minus 16 ft/sec, and a linear acceleration of 96 ft/sq sec (3 g). (Author)
