As ignition method in supersonic air streams, direct injection of dc arc discharges has been proposed and empirically examined. Since the electrodes are buried parallel to the streams in the same level of one of the chamber walls and the discharged arc is pushed into the main air flows by carrier gases, chemically active species are effectively produced and exposed in the combustion chamber. The experiments conducted so far showed 1) this direct arc injection method (DAIM) can ignite methane fuel in the flow of M=2.3 and total temperature T0 as low as 300K and 2) methane air stoichiometric premixed gas is most effective for ignition as the carrier gas used to produce active species and pushed into the main flow.
