Thermo-mechanical Optimization for Optical Instruments: Multidisciplinary Design of 3D Printed Graded Metal Structures, Year 2 (GMS3D)

Completed TRL 4 (started at 3, targeting 4)

Description

Integrate fundamental knowledge of the relationships between the optimized geometries, gradient paths, gradation, mechanical properties and structural performance, i.e. simultaneously optimize structural, material, and thermal design for optical systems to reduce sensitivity to thermal distortions in space which affect precision pointing

Benefits

A new mount design approach using GMS3D for high performance optical instruments Current design approach for optical mounts uses kinematic mounts which only minimize over mechanical constraints in the system, but do not compensate for thermal gradients, which can cause significant distortions. The design approach currently n use involves disjoint, sequential discipline analysis which is labor intensive and inefficient.

How to get involved

This is early/mid-stage (TRL 4) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
