US Patent 7931763 - TiO2 nanoadditive for solid propellant fuel


This patent is based on research from the University of Central Florida and teaches how titania nanoparticles can improve the burn rates of solid propellants. Claim 1 reads:

1. A method for enhancing solid propellant burn rates, comprising the steps of:

providing a solid propellant fuel;

providing nanoparticles of TiO2 additive, where the titania additive is 10 nm or less; and

mixing the nanoparticles of TiO2 additive with the solid propellant fuel,

wherein the nanoparticle additive function as a catalyst to modify burn rate of the fuel.
