为研究双管脉冲爆震火箭发动机共同工作的协同性,以航空煤油和氧气作为燃料和氧化剂,基于双管脉冲爆震火箭发动机系统进行了单管单独工作与双管同时工作的实验,工作频率范围为5～25Hz,对压力和推力的测量结果表明,双管同时工作对单管稳定工作几乎不会产生影响;推力测量数据显示,相同工况下,双管同时工作产生的推力与两单管单独工作产生的推力之和基本相等,无论单管还是双管,在5～15Hz频率范围内,平均推力基本上线性增加,在15～25Hz频率范围内,平均推力增加逐渐趋缓。
In order to study the synergetic work of two-tube pulse detonation rocket engine, the experiments of single-tube single-tube and double-tube simultaneous operation based on two-tube pulse detonation rocket engine system were carried out using aviation kerosene and oxygen as fuel and oxidant. The range of 5 ~ 25Hz, the pressure and thrust measurements show that the double pipe work at the same time on the stability of the single-tube work almost no impact; thrust measurement data show that the same conditions, double-pipe work simultaneously thrust and two single The sum of the thrust produced by the separate work of the pipe is basically the same. Whether the single pipe or the double pipe, the average thrust basically increases linearly in the frequency range of 5-15 Hz, and the average thrust increase gradually slows down in the frequency range of 15-25 Hz.
