Abstract

The article describes an analytical model for the laser ignition of rocket engines and the application to a hydrocarbon gas generator. The model assesses the laser power density required for plasma breakthrough and the amount of energy required and available for ignition. As combustion devices in rocket engines operate in a non-premixed way and under high propellant velocities, CFD is used to examine the local parameters present in the domain and to find a suitable spot for the laser focus.
