Ignition tests of methane fuel under supersonic air streams were conducted with the methane/oxygen combustion jets as an ignition source. The ignition capability of the combustion jets differed with their equivalence ratio φ; ignition at Mach 2 was successful at 2.4kW calorific input power with φ=0.3 jets while 6.5kW power was needed at stoichiometry (φ=1.0). Numerical calculations revealed the relative effectiveness on shortening the ignition delay times for methane/air mixture between active radicals such as H, O, and OH and ordinary oxygen gas O2 abundantly contained in the lean combustion jets. These results overall suggest that ignition by the methane/oxygen combustion jets has an advantage in simplicity from the practical viewpoint over the plasma jet method which needs a heavy electrical power source.
