摘要
在空气流量 1 2kg s左右的地面连管试验台上 ,研究了双凹槽结构的超燃室中多股高温富油燃气射流的超燃特性。试验结果表明 ,超燃点火可靠 ,火焰稳定 ,超燃效率可达 0 8以上。
The experiments were set on the ground connected pipe test station with air mass rate of 1.2kg/s. The characteristics and performances of supersonic combustion of fuel-rich hot gas as reacting jets injected into the combustor with dual-cavity configuration were investigated by means of pressure measurement and photo. 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. So, it can be said that the present new scheme of supersonic combustion is an attractive candidate for ramjet/scramjet.
