设计了单管内径为68mm的六管吸气式脉冲爆震发动机试验系统,以汽油为燃料,空气为氧化剂,成功地进行了多循环爆震试验.结果表明:六管均能形成多次可重复的爆震波;各管之间的相互影响小;共同工作的同步性好;长时间工作起爆稳定.研究结果对多管脉冲爆震发动机的工程应用具有较大的参考价值. A six-tube aspirated pulse detonation engine test system with a single tube inner diameter of 68mm was designed and successfully tested by multi-cycle detonation with gasoline as the fuel and air as the oxidant.The results show that the six tubes can form multiple Repeated detonation wave, small mutual influence among all the tubes, good synchronism of common work, stable initiation for long time work.The research results have great reference value for engineering application of multi-tube pulse detonation engine.
