Description
Summary:We have studied the ignition of fuel sprays and solid rocket fuels by the photo-ignition of single wall carbon nanotube (SWCNT) with a camera flash. Our investigation includes the effects of O(2) concentration and the presence of solid oxidizers such as ammonium perchlorate (AP) on the minimum ignition energy (MIE) as well as the duration and temperature of the reaction. We have shown that by mixing CNT with other nanoparticles and powdered material, the ignition parameters such as ignition delay, burn temperature, and burn duration can be tailored to meet ignition requirements. This approach in photo-ignition of fuel spray and solid fuel provides a suitable method for ignition of liquid rocket engines and solid rocket motors that is scalable from very small to large rockets. Among the advantages of this photo-ignition approach are; very low weight, low power, robust system, with volumetric distributed ignition capability.
