【摘要】 为了研究30 000r/min时延期组合点火管的燃烧规律,进行了高转速条件下延期组合点火管的燃烧试验,以及静态及高转速条件下燃烧速度的测试,得到了高转速条件下延期组合点火管燃烧的临界速度,以及延期时间衰减的燃烧规律。同时,分析了出现断烧的原因,并提出了避免断烧的有效途径,验证试验表明断烧原因分析正确。更多还原

【Abstract】 Aimed at burning law of delay combination ignition tube under 30 000r/min rotation,the burning tests were carried out,and the burning rate under static state,as well as dynamic state was tested.The critical burning rate of delay combination ignition tube under high-speed rotation conditions was obtained,and burning law was gotten.Meanwhile,the reason of cut-off deflagrating was analyzed,which has been verified by verification test,and the improvement was also put forward.更多还原
