| Abstract | Staged fuel injection plays an important role in designing of a scramjet combustor with balanced performance of combustion efficiency, flame stability, engine unstart, heat release distribution and subsonic/supersonic combustion mode transition. In this paper, a Mach 2.5 model combustor with two-staged fuel injections has been tested in airflow of total temperatures of 1500 K and total pressures of 1.3 MP. Supercritical kerosene with temperature of about 760 K was injected through two integrated fuel injection/flame-holder cavity modules. The effects of fuel injection distribution (injector spacing and fuel ratio) on the combustion pressure rise, thrust increment, lean blowout limit, wall temperature distribution and engine "unstart have been examined. |
