Adding nanoparticles as a catalyst to solid propellant fuel to increase and enhance burn rates of the fuel by up to 10 times or more and/or modifying the pressure index. A preferred embodiment uses TiO2 nanoparticles mixed with a solid propellant fuel, where the nanoparticles are approximately 2% or less of total propellant mixture. The high surface to volume ratio of the nanoparticles improve the performance of the solid propellant fuel.
We claim: 1. A composite solid propellant having a catalyst, consisting essentially of:a composite solid propellant fuel; anduncoated nanoparticles of TiO2 additive consisting of nano-sized arrays of particles are mixed with the solid propellant fuel to produce a final propellant mixture having 0.4% of nanoparticles of TiO2 consisting of nano-sized arrays of particles with a diameter of 10 nanometers or less, wherein the uncoated nanoparticles of TiO2 act as the catalyst to increase the burn rate of the composite solid propellant for enhancing solid prop...
