The NASA Glenn Research Center supports and promotes research in advanced propulsion and propellants. This research encompasses both air-breathing fuels and space flight rocket propulsion and propellants. The air-breathing fuel research is addressed with pulsed detonation engine fuels and the majority of the content below addresses our work in metallized gelled fuels, gelled hydrogen, atomic propellants, and very advanced rocket propulsion, including nuclear electric and nuclear thermal propulsion.
Small Business Innovation Research (SBIR) Summary
Fuels and Space Propellants
This focused SBIR topic is designed to foster the development of higher density, higher Isp, and more operable propellants. In the development of aeronautics and space technology, there have been limits to vehicle performance imposed by traditionally used propellants and fuels. Increases in performance are possible with either increased propellant specific impulse, increased density, or both. Safety of flight systems will also be increased by using denser, more viscous propellants and fuels.
Many challenges have been overcome recently in the discovery and synthesis of propellants which can have higher performance than traditional O2/H2, O2/RP-1, and aircraft fuels. This focused SBIR topic provides a substantial infusion of resources that can enable the commercialization of these fuels and propellants for aeronautics and space applications.
The space flight applications of the higher performing propellants include high density monopropellants for upper stages and the on-board propulsion for small spacecraft.
Higher energy fuels, such as N4, N6, BH4 or others would be more applicable to launch vehicles. Aeronautical uses are directed toward improving the storage density over typical JP type fuels and related research in endothermic fuels. These fuels and their commercialization will be the major products of the SBIR topic.
This SBIR topic will promote development and demonstration of propellants with NTO/MMH performance, which are self pressurizing, and less toxic. Examples include mixtures of nitromethane, nitrous oxide (N2O), hydroxyl ammonium nitrate (HAN), ammonium nitrate (NH4NO3), aluminum, water, and/or other species (this list is not all inclusive). Gelled monopropellants are also of interest for safety enhancements.
It will also promote development of high energy density species, whether monopropellant or bipropellant, which offer the performance of O2/H2 while offering significantly higher system density. Possible examples include cubane, strained-ring compounds, polymeric oxygen (O4, O6, O8 … ), polymeric nitrogen (N4, N6, N8 … ), and and B-N analogs of prismane (B3N3H6), among others.
