A new scheme for investigation of supersonic combustion of kerosene fuel

To strengthen the performances of supersonic combustion of kerosene fuel, a new scheme is suggested, which is an attractive candidate for the extensive application. The supersonic combustor with dual-cavity and preburner is adopted in the present scheme. The hot gas as a kind of piloted energy was produced by the preburner to ignite the supersonic combustion of kerosene, which was injected into the supersonic combustor from the bottom of the dual-cavity. The experiments were set on the ground connected pipe test station with air mass rate of 1.2kg/s. The results show that the ignition of supersonic combustion is reliable and the combustion flame is stable. Also, the efficiency of supersonic combustion is more than 0.80.
