Abstract:

Radiative ignition of energetic materials such as solid propellants and blackpowder have been investigated using a variable pulse width, high-energy Ndglass laser. Quantitative measurement of the relationships between laser energy,laser pulse duration, and percent surface irradiation on ignition delay and ignition threshold have been made. The effect of molecular oxygen concentration on ignition threshold in solid propellant initiation has also been determined. A two-color laser ignition method for solid propellant ignition using infrared IR surface pyrolysis and gas phase ultraviolet UV photolysis and multiphoton is examined
