GFTS® Design Gallery
Previous Designs & Spaceflight Models
Over the last decade, Technology Applications, Inc. has designed and assembled hundreds of graphite thermal straps for use in aerospace, laboratory and defense applications for customers like NASA, JAXA, ESA, Airbus, LMCO, and many others who cannot be named due to NDA's and cybersecurity policies. These straps are not only a testament to our expertise, but our ability to accommodate a vast array of customer demands. All of these assemblies were designed for the optimization of heat transfer from power dissipation components such as cryocooler compressors, radiators, antenna arrays, DAQ's systems, electronics boxes, radar electronics, or optics that dissipate anywhere from forty watts to several hundreds of watts and require an efficient, lightweight thermal conductor for transferring heat to the heat rejection interface.
The following are just a few examples of some of our GFTS® designs and flight units.

Low-Mass Optimized End Fittings: NASA's SPICE on SORA
Straps used by NASA with very little interface area to attach to, and with extremely limited mass requirement. By moving bolt holes out to the sides, and removing the traditional "step" in the fitting, our engineers were able to remove an additional 40% from the end fitting mass.
