| Abstract Scope |
Over the past decade, additive manufacturing (AM) has matured and been infused into numerous spaceflight missions. Simultaneously, deployable structures have become more common on spacecraft. These structures seek to maximize packing efficiency using complex systems that challenge traditional manufacturing methods.
An example is the spring mechanisms developed for the NISAR satellite antenna. The mechanism required high torque and was severely volume constrained. This resulted in the use of high aspect ratio rectangular cross-section torsion springs. These springs represented the state of the art for manufacturing. Significant testing, development, and rework was needed for the traditional springs to meet requirements.
These issues can now be avoided using AM. By additively manufacturing torsion springs embedded in the mechanism structure, novel geometries are possible. Thus, increasing performance while decreasing complexity and part count. JPL will present on the latest research to monolithically print compliant mechanisms for spaceflight applications. |
