Deployment Repeatability of a Truss Structure Utilizing Integral Composite Hinges

摘要

An overview of a deployable truss structure utilizing doubly slit cylindrical shells as integral composite hinges is presented along with a measurement system and results of deployment repeatability. The measurement system was developed and built as part of a project in the Space Scholars Program at the Air Force Research Laboratory at Kirtland AFB. Previous deployment repeatability tests of integral hinges at the University of Colorado focused on single members and not an entire truss structure. The largest translation accumulated over the course of the deployments was 363um and the largest rotation was 0.1 degrees. The largest increment between deployments was 207um and 0.07 degrees.
