摘要
为了强化煤油超燃性能 ,提出了一种采用双凹槽和预燃室结构 ,利用从预燃室喷出的高温燃气去引燃从凹槽内喷出的煤油 ,实现煤油超燃过程的具有广泛应用前景的超燃新方案。试验是在空气流量 1 .2kg/s左右的地面连管试验台上进行的。试验结果显示 ,超燃点火可靠 ,火焰稳定 ,超燃效率可达 0 .8以上。
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.
