NASA Langley Research Center is developing key structures and mechanisms technologies for micron-accuracy, in-space deployment of future science instruments. Achieving micron-accuracy deployment requires significant advancements in deployment mechanism design such as the revolute joint presented herein. The joint presented herein exhibits a load-cycling response that is essentially linear with less than two percent hysteresis, and the joint rotates with less than 7 Nmm of resistance. A prototype reflector metering truss incorporating the joint exhibits only a few microns of kinematic error under repeated deployment and impulse loading. No other mechanically deployable structure found in the literature has been demonstrated to be this kinematically accurate.
