【摘要】：為縮短脈沖爆震室軸向長度以及爆燃向爆震轉變距離,設計加工了螺旋脈沖爆震室,采用液態(tài)汽油為燃料,空氣為氧化劑,進行了一系列實驗.在實驗過程中,對比研究了常規(guī)直管脈沖爆震室以及螺旋脈沖爆震室的爆燃向爆震轉變性能;并分析研究了螺旋脈沖爆震室多循環(huán)工作特性.結果表明:與直管脈沖爆震室相比,螺旋脈沖爆震室爆燃向爆震轉變距離至少縮短了約11.2%;螺旋脈沖爆震室可以在5~20Hz頻率下穩(wěn)定工作;螺旋脈沖爆震室設計方案可行.
[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.
