摘要
简述了脉冲爆震火箭发动机(PDRE)的实验系统,在12Hz的频率下,以煤油为燃料,以氧气为氧化剂,进行了当量比在0.5—1.7下推力随当量比变化的实验,并计算出比冲值。结果表明:当量比在0.5—1.7之间时,此PDRE的推力和比冲随着当量比的增加而增加。
We present the experimental system of a pulse detonation rocket engine (PDRE) and perform an experiment on its thrust change with that of equivalence ratio using kerosene as fuel and oxygen as oxidizer at the equivalence ratio between 0.5 and 1.7 and at the frequency of 12 Hz. Then we calculate its specific impulse value. The experimental results indicate that its thrust and specific impulse inerease with the increase of its equivalence ratio.
