EMP Protection for AFGSC Generators and HVAC Equipment

The proposed generator and shelter solution for AFGSC stakeholders will be a larger form factor and a significant adaptation of SLNT’s current commercial offerings with new technical components and manufacturing techniques that include a magnetic RF-tight door entry (adapted from SLNT’s current Silent Pocket patented seal), RF Bandpass, earth grounding, collapsibility, packability, wearability and deployability in rapid fashion. Under this Phase II effort, SLNT will develop multiple Faraday shelter variants based on AFGSC requirements whose use cases for EMP protection range from generators to HVAC to electrical components.  Using similar materials found in SLNT bags, backpacks, and pouches, the SLNT team will adapt the core technology into a prototype “cinch” model. Furthermore, SLNT will develop a more traditional EMP protection prototype utilizing a wire mesh cage approach that will allow for cost and effectiveness comparison between the two approaches.  Both of these prototype variants are described in more detail below. SLNT’s Intellectual Property (IP) and technical methodology through Computer Aided-Design (CAD) tools like Solidworks will allow us to build more complex and technical products like the proposed shelter solutions while maintaining full efficacy of the desired functionality. SLNT will use all advanced manufacturing capabilities at hand such as high-frequency dielectric welding, technical sewing, laser cutting, and 3D printing for prototype fabrication. Using SLNT’s partners Keystone Compliance, MIT Lincoln Labs (MITLL), Advanced Functional Fabrics of America (AFFOA) SLNT will be able to stress test the prototypes at every stage of development to make sure that the shelter maintains benchmark metrics of full or selective RF signal attenuation and physical integrity for designated materials and prototypes. SLNT will be field testing with industry partners who will simulate real world scenarios ensuring that the shelter performs above and beyond in all requirements. The RF testing systems at partner facilities specifically have Anechoic chambers with the ability to cover a Radar cross section (RCS) of 800MHz - 100GHz. SLNT will test the proposed Faraday shelter solution as well as stand alone materials in the most dynamic and comprehensive ways possible.
