【摘要】：为缩短脉冲爆震室轴向长度以及爆燃向爆震转变距离,设计加工了螺旋脉冲爆震室,采用液态汽油为燃料,空气为氧化剂,进行了一系列实验.在实验过程中,对比研究了常规直管脉冲爆震室以及螺旋脉冲爆震室的爆燃向爆震转变性能;并分析研究了螺旋脉冲爆震室多循环工作特性.结果表明:与直管脉冲爆震室相比,螺旋脉冲爆震室爆燃向爆震转变距离至少缩短了约11.2%;螺旋脉冲爆震室可以在5~20Hz频率下稳定工作;螺旋脉冲爆震室设计方案可行.
[Abstract]:In order to shorten the axial length of pulse detonation chamber and the distance from deflagration to detonation, the spiral pulse detonation chamber was designed and manufactured. A series of experiments were carried out using liquid gasoline as fuel and air as oxidant. In this paper, the deflagration to detonation transition performance of conventional straight tube pulse detonation chamber and spiral pulse detonation chamber is compared, and the multi-cycle operation characteristics of spiral pulse detonation chamber are analyzed. The results show that: compared with the straight tube pulse detonation chamber, The distance from deflagration to detonation in spiral pulse detonation chamber is at least 11.20.Spiral pulse detonation chamber can work stably at 5~20Hz frequency, and the design scheme of spiral pulse detonation chamber is feasible.
