The thermal protection and passive thermal system Technical Discipline Leads (TDL) at the Johnson Space Center are in need of a visual aide and short concept demonstration animation that shows a new automated manufacturing process, using robotic additive manufacturing methods, being pursued for development as part of the effort to address the existing technical gaps for future human exploration missions.
The 3D rendering of the envisioned concept, with short animations showing the printing process of a spacecraft thermal protection heat shield and pressure vessel (see guidance below), will help the TDL’s convey the ideas to NASA management, universities and private companies for funding and partnership opportunities in this development endeavor.
1. The graphics and animation should depict a modern automated manufacturing site in which large space structures, note dimensions in above sketches, are being fabricated and covered with thermal protection materials. The materials would be deposited on the structures using additive manufacturing deposition techniques.
2. The artistic concept should be original and not copying the robots shown in the Partner Space. Orion structural images found in the internet can be used as guidance and included in the project. Other vehicle concept could be used but should be submitted for approval by the TDLs before they are included in the work.
3. The rendering must have a realistic appearance with the proper scaling and the space structures depicted are not limited to those in the Partner Space.
The process should show two robotic arms performing the printing and final machining of the thermal protection system material.
A feed-bay where multiple printing heads reside should be considered as part of the CAD.
The CAD must show some form of material storage (mixing tank) or filament feed system for the printing process.
The process should show the deposition on a composite material structure for the thermal protection system printing.
There must be a separate CAD showing the 3D printing of a metal spacecraft pressure vessel structure.
