摘要

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: For the purpose of reducing the axial length of pulse detonation chamber and the DDT(deflagration to detonation transition) distance by the spiral pulse detonation chamber, the results of experimental investigation on spiral pulse detonation chamber using liquid gasoline and air mixture were presented. Results show that, compared with straight pulse detonation chamber, the DDT distance has reduced 11.2% at least by the spiral pulse detonation chamber; the spiral pulse detonation chamber can work stably under the frequency of 5~20Hz; the spiral pulse detonation chamber design is a successful one.
