We have studied the ignition of fuel sprays and solid rocket fuels by the photo-ignition of single wall carbon nanotube SWCNT with an ordinary camera flash. Our investigation includes the effects of O2 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 adjusted. We believe 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. Among the advantages of this approach are a very low weight and a robust ignition method, and it enables volumetric distributed ignition of fuel sprays and solid fuels. The proposed method is scalable for applications in very small as well as large liquid rocket engines and solid rocket motors.
