title = "Laser ignition of a research 200N RCS LOx/GH2 and LOx/GCH4 engine",
abstract = "An extensive test campaign has been conducted to assess the feasibility of the implemen- tation of laser ignition in cryogenic RCS and OMS engines. The 200N research thruster used for this purpose is a single-coaxial injector element combustion chamber. A table-top laser with a system of mirrors and a lens was used as ignition system. This paper reports lo- cation of energy deposition, levels of energy deposited and associated ignition probabilities for the propellant combinations LOx/GH2 and LOx/GCH4. Gas-breakdown (plasma) ig- nition and ablation ignition were both tested. Minimum energies were lower for LOx/GH2 (72 mJ) than for LOx/GCH4 (92 mJ) and lower for ablation (14.5 mJ for LOx/GH2 and 61.7 mJ for LOx/GCH4) than plasma ignition. Regions for successful energy deposition for 100% ignition success were also identified. Finally it has been established that the dynamic of ame growth determines ignition overpressure in a laser ignited chamber. A separate paper has been dedicated to the discussion of the in uence of pre-ignition conditions and flow fields on altitude ignition.",
