【摘要】 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.更多还原

【Abstract】 A experimental system for six-tube air-breathing pulse detonation engine(PDE) with the single tube’s inner diameter of 68 mm was designed.Using gasoline as fuel and air as oxidizer,multi-cycle experimental study was successfully performed.The results show that all of the six tubes can obtain continuous detonation waves.The interaction among the tubes is not obvious and the engine can work synchronously and stably.The research results are very helpful to engineering applications of multi-tube PDE.更多还原
