Nostromo, LLC (Nostromo) proposes to: (1) optimizes propellant combustion spectrum to produce radiation in a wavelength that optimally charges phosphors; (2) develop and refine a translucent epoxy matrix that can be incorporated into 40mm training and operational cartridges; (3) design, optimize and test phosphors that are configurable in a thin translucent epoxy and can be readily charged (radiated) by light emissions form combustion gases produced by combustion of propellants (in the cartridge and barrel); and (4) incorporate a modified propellant mix into a 40mm cartridge, where the aft end of the projectile will encase phosphors in a protective translucent epoxy. ???????
