The Engineering and Technology Directorate (ETD) provides a comprehensive set of machining, composites, precision 
assembly, electroplating, additive manufacturing, logistics, and 
inspection services for aerospace applications.  From machining and composites to electroplating and additive manufacturing, ETD equips its customers with the tools necessary to push the boundaries of flight and exploration.

At the forefront of this effort is the Advanced Composite Materials Lab (ACML), a hub of collaboration where engineers and scientists come together to drive the development of cutting-edge aerospace components. This lab not only supports the agency’s flight and research activities but also serves as a creative space where ideas transform into tangible technologies.

Precision Modifications for the Roman Space Telescope: Optimizing SIIPs for Enhanced Performance

A key project highlighting ETD’s prowess was the modification of the Sensor Interface and Instrument Plates (SIIPs) for the Roman Space Telescope (RST). These plates are critical, as they align optical components within the spacecraft, demanding unmatched precision and reliability.

Each SIIP was meticulously characterized for its as-installed configuration, and assigned a unique serial number and drawing to ensure tailored modifications. The interface between the SIIPs and the instrument cluster is designed to be highly precise, and the project employs multiple processes to characterize the as-installed configuration. Consequently, each plate is assigned a unique serial number and drawing for modification. ETD’s Advanced Manufacturing Branch collaborated with the project team to understand the specific needs and modification requirements associated with these SIIPs.

Advancements in Composite Machining and Bonding for Next-Generation Gamma-Ray Observatory Development

The ACML was also pivotal in the development of the All-sky Medium Energy Gamma-ray Observatory-X, a proposed next-generation medium-energy gamma-ray MIDEX (Medium Explorer) telescope with a carbon-fiber composite structure. The carbon-fiber structure is designed and manufactured with materials for high stiffness, structural stability, and low weight and allows for gamma-ray pass-through for the detectors. The design process was iterative, with on-site composite manufacturing enabling rapid prototyping and adjustments based on real-time feedback. On-site composite manufacturing allows for quick response, low cost, and design input for these highly engineered structures.

Through projects like the Roman Space Telescope and the All-sky Medium Energy Gamma-ray Observatory-X, ETD demonstrates how advanced manufacturing techniques are integral to the aerospace industry’s quest for knowledge and discovery. By harnessing the power of collaboration and innovation, ETD is paving the way for future missions that will expand our understanding of the universe, one engineered component at a time. As the agency continues to reach for the stars, ETD stands ready, committed to pushing the boundaries of what is possible in aerospace engineering.
