Captive cable coil and its application to a regulator for deploying a lengthening piece of a space instrument

摘要

So as to adjust the deployment of a lengthening piece of a space instrument, a captive cable coil (34) coupled to a centrifugal brake by a speed multiplier is used. The cable (40) is wound onto the coil (34) in the form of a single strand imprisoned in a roughly helical- shaped throat (38) formed, for example by machining, on the outer surface of the coil. One outer portion (42a) of the partition separating two adjacent spires of the throat is folded down onto the cable so as to prevent its volume from swelling.
