Combustor models with a strut were tested at an airflow of Mach 2.4. A vitiation air heater supplied an airflow with stagnation temperature of 800 to 2,100 K and stagnation pressure of 1 MPa. A strut with a leading edge geometry that greatly disturbed the airflow brought higher mixing and combustion efficiencies. When the strut was located downstream in the combustor, it helped ignition and flame-holding of fuel injected from a step parallel to the airflow, and the pressure increase due to combustion was limited downstream of the step. Increasing the diameter of the parallel fuel injector on the strut did not affect combustion condition greatly. Increasing the diameter of the parallel fuel injector on the sidewall promoted combustion. Dual plasma torches succeeded in igniting the fuel simultaneously in each channel beside the strut. Ignition was attained more easily in a combustor with a strut than in a combustor with no strut. Ignition became difficult with an increased equivalence ratio and parallel fuel injection from the strut.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
