Laser ignition of elastomer-modified cast double-base (EMCDB) propellant using a diode laser

Abstract

An experimental study was conducted to investigate laser ignition using a diode laser for elastomer-modified cast double-base (EMCDB) propellant in order to develop more liable and greener laser ignitors for direct initiation of the propellant. Samples of the propellant were ignited using a 974nm near-infrared diode laser. Laser beam parameters including laser power, beam width and pulse width were investigated to determine their effects on the ignition performance in terms of delay time, rise time and burn time of the propellant which was arranged in several different configurations. The results have shown that the smaller beam widths, longer pulse widths and higher laser powers resulted in shorter ignition delay times and overall burn times, however, there came a point at which increasing the amount of laser energy transferred to the material resulted in no significant reduction in either delay time or overall burn time. The propellant tested responded well to laser ignition, a discovery which supports continued research into the development of laser-based propellant ignitors.

“…De Narendra et al [12] studied ignition of high-nitrogen materials using a CO 2 laser, focusing on ignition delays and ignition energies. Herreros and Fang [13] used a laser diode to study the ignition of elastomer-modified cast double-base propellant. Their study focused on measurements of ignition delay times, rise times and burn times.…”

“…A self‐built experimental platform was used for laser ignition experiments, and the schematic diagram of the experiment system is shown in Figure 2A. [ 38 ] All samples were 15 × 3 × 1 mm 3 and ignited using an 800 nm diode laser at 25°C, and the laser power was 50 W. The laser spot diameter was ~3 mm. Laser ignition mode was mono‐pulse excitation mode.…”

Coulomb Explosion Dynamics of Multiply Charged para-Nitrotoluene Cations

“…Electronic excitation, ionization, and electron-ion coupling play crucial roles in shock initiation of energetic materials. − In particular, ionization of the parent energetic molecules lowers the barrier to molecular dissociation in explosives including TNT, RDX, and PETN, thereby facilitating the initiation of detonation. , Moreover, laser initiation of photoactive explosives produces electronic excited states and ions to selectively initiate detonation. − Hence, knowledge of the initial dissociation pathways of ionized energetic molecules is important for advancing the understanding of initiation mechanisms in energetic materials and designing safer photoactive explosives.…”
