This paper reports the results of experiments with hydrogen-fuel-cooled flameholders. Fuel cooling of the flameholders is necessary because the temperature of the incoming air is extremely high during high Mach number flight. Two kinds of fuel injection were tested for the flameholder; crosswise and flow-directional fuel injection. Visual observation and gas analysis of the flame showed that the former type of fuel injection made the flame unstable and caused blow-off when the combustor inlet velocity was increased to 80 m/s, possibly causing damage to the other flameholders. Flow-directional fuel injection demonstrated satisfactory performance over the required range of operation, albeit with narrow flame area.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
