An advanced space rotary power transfer device
Abstract
A new electrical signal and rotary power transfer device has recently evolved from ball-bearing and electrical-transfer technologies. This hybrid device, known as a roll ring, has been tested extensively since the late 1970s and has demonstrated important operational advantages in a wide variety of signal and power transfer configurations. A high power version has been developed and evaluated. This paper describes this latter roll ring configuration. The paper also summarizes test results.
