Laser Ignition for Pulse Detonation Engines
The high pressures and resultant momentum flux out of the chamber generate thrust. The ignition system of PDE has always posed problems in commercial applications. Microwave and laser-induced detonation in the mixture ofhydrogen with flake aluminum particles is simulated based on Eulerian approach. Minimum pulse energy of detonation is calculated for different parameters of laser pulse, mass fractions of particles, and compositions of gas mixture. The threshold intensity of optical breakdown on individual metal particle, and its dependence on contributing factors (particle radius, location of particle, total energy and time of laser pulse, radius of laser spot) are studied.
