US Patent 7931763 - TiO2 nanoadditive for solid propellant fuel

http://www.freepatentsonline.com/7931763.html

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.
